    Notes: A multi-stage pilot fermentor was designed which consists of nine stainless steel cylindrical compartments 2 ft. in length and 8 in. in diameter, joined end to end, giving a tube with a total length of 18 ft. The whole apparatus was mounted with its axis in a horizontal plane. Each compartment was sealed off from its neighboring compartment by a separatory plate having a 1-in. overflow hole in the upper half. Shafts 9½ feet long extended from each end of the fermentor through the compartments to the center. Agitation was provided by a multitude of stainless steel blades mounted at right angles to the shafts and spaced at regular intervals along the shafts. Stationary, stainless steel comb-shaped baffle plates were installed vertically at the bottom of each compartment to increase mixing efficiency. Constant leaving and re-entering of the fermentation liquor by the blades upon rotation imparts a shattering of the liquid surface thus preventing the accumulation of mycelial aggregates on the walls above the fermentation liquor. The mechanical performance of the described fermentor has proved excellent and several trial fermentations (antibiotic formation and steroid bioconversion) are described.

    Notes: Ferrocyanide-treated cane molasses was fermented in 2.5-l. Pyrex tower fermenters using pellets of Aspergillus niger, grown in beet molasses, as an inoculum. The success of the process depended on accurate control of the ferrocyanide concentration in the fermentation mash. Highest yields (up to 80% conversion of available sugar in 8 days) were obtained when the ferrocyanide concentration was 20 p.p.m. at the start of fermentation and then increased to 80-150 p.p.m. at the 24-hr. period. Addition of phosphate, nitrate, or methanol to fermentation mash did not increase rate of acid production or final yield.

    Notes: The ability of a number of Ustilago species, especially Ustilago maydis (DC.) Cda., to produce lysine and threonine was investigated. The organisms were grown in shake flasks or in 10-l. fermentors. Lysine and threonine were found to be excreted into the medium both in the free and bound form. The bound amino acids could be released by acid hydrolysis or by enzymes from autolyzed cells. The optimal conditions for the release by autolysis were, in the case of Ustilago maydis (DC.) Cda., pH 4.3 and 45°C. An enzyme that could liberate lysine from the bound form(s) occurring in the broth was extracted from cells of Ustilago maydis (DC.) Cda. It exhibited an apparent pH optimum near 4.0. The effect of pH and temperature during the growth phase on the yield of lysine and threonine was studied in 10-l. fermentations.

    Notes: The ability of Ustilago maydis (DC.) Cda. to grow and to produce lysine and threonine was investigated in shake flask cultures. Growth and production of lysine and threonine increased markedly when aeration was increased. The optimal ratio of glucose to diammonium phosphate in the medium seemed to be approximately 10:1. Ammonium phosphate, ammonium sulfate, ammonium chloride, ammonium nitrate, sodium nitrate, urea, aspartic acid, glutamic acid, and glycine were readily used as nitrogen sources. Growth and amino acid production was poor on ammonium carbonate, ammonium acetate, ammonium citrate, trimethylamine, and betaine.U. maydis (DC.) Cda. was found to grow on a number of different carbohydrates. Besides D-glucose the organism could utilize D-mannose, D-galactose, D-fructose, L-arabinose, D-xylose, D-ribose, sucrose, maltose, and the polyalcoholes D-sorbitol, D-mannitol, and i-inositol. Pectin, dextrin, and corn starch treated with α-amylase could also be used but not untreated corn starch or lactose, cellobiose, D-sedoheptulose, glycerol, or D-glucosamine. The formation of lysine and threonine was better with disaccharides and hexoses than with pentoses.No specific effects on the formation of lysine and threonine could be observed from changes in the concentration of calcium, sodium, potassium, magnesium, zinc, iron, copper, manganese, cobalt, or molybdenum. The requirement of metal ions for growth is discussed.

    Notes: An apparatus is described for the aeration of a series of tissue cultures at rates which may be varied independently for each vessel. The composition of the aerating gas can be adjusted to any desired percentages of CO2 and O2. While designed particularly for study of the aeration requirements of submerged tissue growth, the equipment is equally adaptable for study of submerged growth of bacterial and other systems. The apparatus has been designed for future scale-up and is adaptable to both the overlay and bubble-through types of aeration. Flow rates necessary for producing mixtures of 5.0% CO2 and 95.0% air or 5.6% CO2, 14.0% O2, and 80.4% nitrogen are given. The described system has been operated satisfactorily and has proved to be an inexpensive and useful research tool.

    Notes: Aeration in shaken flasks appears to take place primarily by absorption of oxygen in the thin film of fluid deposited on the flask walls. Marked improvement in aeration efficiency can be had by breaking up these films with an independent baffling surface. This improvement can be combined with an improved closure to give uniform and efficient shaken flask aeration.

    Carbon balance in high rate dissimilation of acetic acid in semicontinuous methane fermentation (1962)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The nature of anaerobic methane fermentation has been studied extensively over a period of about three years by means of 10-l. semicontinuous fermenters, with ethyl alcohol and calcium acetate as carbon and energy sources. The inoculum for the two systems was isolated by enrichment techniques from primary sewage sludge and used to initiate the processes. No subsequent seeding was necessary. The fermentation was started with a substrate carbon concentration of 50 mmole/l. which was gradually increased to 400 mmole/l.; this means that an increase of substrate level from 3000 ppm to 24,000 ppm of acetate and from 2300 to 18400 ppm of alcohol medium were effected during the study. Such high acetate tolerance of the methane organism does not appear to have been reported before; it was the results of adaptation by the organisms in a semicontinuous culture for a period of 30 months. Effect of supplementary available nitrogen on the rate of gas production at different carbon levels (acetate) was also studied. It was found from the gas analyses that CH4: CO2 ratios were always more than 2 to 3 times the theoretical values, when acetate was used as substrate carbon. At some stages of acetate breakdown the concentration of hydrogen in the gaseous products was found to be as high as 8-9%, a very significant feature of this fermentation. Although sulphate ions were carefully excluded from the constitutents of the media (Analytical reagent chemicals and double-distilled water used throughout) during the period of study (30 months), contaminants later identified as Desulphovibrio desulphuricans were found throughout the study. Morphological study of the organisms reveal that they are short rods appearing in individual or chain form, highly motile, gram-positive and nonflagellated, similar to Methanobacterium söhngenii Barker.

    Notes: Studies were made of oxygen transfer and power in 20-1. novobiocin fermentations with five sizes (23-60% of the tank diameter) of geometrically similar flatblade turbine impellers. The influence of changes in apparent viscosity on oxygen transfer and power was found to be related to impeller diameter. At constant agitator speed the oxygen availability rate (OAR) decreased with increase in apparent viscosity, but the magnitude of the reduction was less with a small impeller than with a large one. At constant power input the small-diameter impeller (23% of tank diameter) gave an OAR about 8 times that of the large one (60% of tank diameter) when tested in viscous beer, whereas with sulfite or yeast all impeller diameters gave the same OAR. Impeller tip velocity correlated with OAR independently of diameter for the five turbine sizes examined. The power required for optimal novobiocin yields increased with increase in turbine diameter, but the yields were independent of diameter at equal OAR.

    Notes: The adsorption of methylene blue from different aqueous solutions by dead yeast cells follows Freundlich's law when the percentage of dead cells varies from 0 to 100. When the Fink and Kühles methylene blue was used, there was observed a linear relation between the percentage of dead cells and the dye concentration at the equilibrium. The experimental errors were measured. A simpler and more precise colorimetric method for determining the percentage of dead yeast cells is deseribed.

    Notes: The rate of oxygen absorption by aqueous sodium sulphite solutions in tower-type fermentors up to 6 in. in diameter was related both to tower diameter and to the number of sintered Pyrex disks used for dispersing air entering the towers. Maximal rates of absorption were obtained in towers 2.5 in. in diameter. Under comparable conditions, rates of oxygen transfer in towers containing one aeration disk were approximately 30% higher than those in similar towers containing two or more disks. In towers greater than 6 in. in diameter, the absorption rate was independent of vessel diameter and number of aeration disks when more than one disk was used. Bubble coalescence was the main cause of the difference in the rate of oxygen absorption.

    Notes: The sandwich paper electrophoresis technique, such as that of Foster (1952b), was modified to permit routine examination of as many as 15 samples of materials such as bacterial cultures, simultaneously, and with greater rapidity than with paper chromatography techniques. By the use of borate buffer at pH 9.6 with aniline hydrogen oxalate for development, materials such as glucose, fructose, 2-ketogluconic acid, and 5-ketogluconic acid could be separated in three hours.

Closed Lucite rocking-box units containing 5 liters of culture media can produce 1 to 2 g. (dry weight) per day of fully deuteriated algae or of fully deuteriated, fully 15N-substituted algae. Racks for six such culture units are readily constructed from commerically available parts. Operation has been routine and essentially trouble-free. The algae produced have proved to be an excellent source of completely isotopically substituted metabolites.

    Notes: A strain of Torulopsis magnoliae, an osmophilic yeast isolated from flowers, produced an extracellular hydroxy fatty acid glycoside of sophorose which was easily recoverable as a heavier-than-water “oil”. The yield of this product was greatly increased and the nature of the hydroxy fatty acid portion of the molecule was modified, within limits, by the addition of fatty acid esters, hydrocarbons, or glycerides. Yields of hydroxy fatty acids of up to 90% of the substrate added were achieved. Commercially available substrates such as tall oil fatty acids, molasses, and corn steep liquor could be used. Good aeration was necessary, and control of the concentration of nitrogenous substrates and of temperature improved the yields.

    Notes: The linearity between weight and volume increases, which takes place when kernels of corn and sorghum are immersed in water, was established experimentally. The rate of volume increase was correlated according to an equation analogous to the diffusion equation. The coefficients of volume increase obeyed the Arrehenius equation. The results would be of practical value in designing steeping vessels, as well as of theoretical interest in elucidating the mechanism of water diffusion in cereal grains.

    Notes: A laboratory bench set-up for the continuous chemical sterilization of microbiological media using β-propiolactone was developed. The apparatus permits the sterilization of up to 4 liters/hr. of liquid media. The parameters of hydrolyzing time and temperature necessary to reduce the β-propiolactone to nontoxic levels were determined using a E. coli-nutrient broth system. The sterilization technique was applied successfully to a variety of media, and its potential usefulness on an industrial scale is discussed.

    Notes: Manufacturing of plastic (PVC) single-dose ampoules for liquid smallpox vaccine is described. The green stained vaccine is injected in polyvinyl chloride tubes which are then sealed by high frequency welding to make ampoules of 16 mm. length. The tendency for desiccation of the filled vaccine at elevated temperature is considered as an advantage, since it provides a visible indication of previous improper storage. The ampoule is opened by cutting with scissors and vaccine is squeezed out directly on the skin.

    Notes: Dissolved oxygen levels in fermentation systems are affected by (a) gas flow rate, (b) degree of agitation, and (c) oxygen partial pressure in the gas. Since the first two variables cannot easily be separated, a method for dissolved oxygen control has been devised based on the variation of oxygen partial pressure in the gas. Oxygen and nitrogen are fed to a special mixing valve capable of varying the proportions of the two gases while keeping the total flow rate constant. A dissolved oxygen electrode and control system adjust the valve setting to automatically maintain a preset oxygen level. Oxygen analyzers, monitoring the inlet and outlet gas streams, provide additional information from which oxygen absorption and uptake rates may be determined. The system provides a means for the quantitative and independent study of aeration and agitation effects. In addition, it offers a basis for routine control of oxygen levels in plant fermentation equipment.

    Notes: Fungi and bacteria taken from fuel systems were allowed to grow in jet fuel (or hydrocarbon)-salt solution mixtures and the layers were analyzed for surfactant properties. The fuels included both JP-4 and JP-5 types and an alkylate bottom fraction. Controlled surface activity was imparted to some samples by adding minute quantities of either petroleum sulfonates or petroleum naphthenates. Analyses after growth periods of 2 to 14 weeks failed to show any significant increases in the surface active properties of any fuel or hydrocarbon sample. In all cases, there was either little change or else the surfactant effect was reduced slightly. Opposed to these findings, examination of the aqueous bottoms revealed that microbial growths did effect increases in their surface active properties.

    Notes: It would appear from these data that indeed asphalt degradation by bacteria does occur and can be rather rapid under laboratory conditions. The types of bacteria capable of degrading asphalt are diverse. The effects of temperature, pH, and oxygen tension on asphalt degradation are important but not always critical. The optimum conditions vary for different organisms. There are differences in the mechanisms of asphalt assimilation and degradation. There is a specificity of action by different bacteria which most likely involves the chemical components of the asphalts and the enzymatic action of the microorganism.

    Notes: The distribution of various cell constituents of Bacillus megaterium has been studied in an aqueous two-phase system containing the two polymers dextran and polythylene glycol. The difference in behaviour between cell walls, lipid granules and soluble cell material are such that a considerable fractionation of a suspension of disrupted cells may be obtained after a few counter-current distributions. A mixture of whole cells and protoplasts can also be fractionated in this phase system. If sodium chloride is added to the phase system, vegetative cells and spores can be separated from each other.

    Determination of oxygen and carbon dioxide using a paramagnetic oxygen analyzerIssued as N.R.C. No. 7385. (1963)

    Notes: A method by which a paramagnetic oxygen analyzer is used to determine oxygen consumption and carbon dioxide production during aerobic fermentation of Torulopsis utilis is described. The volume of carbon dioxide produced is not necessarily related to the volume of oxygen consumed by the microorganisms. For this reason, all carbon dioxide is removed from the effluent gas before it enters the analyzer when determining oxygen consumption. A method for calibrating the analyzer to correct for this removal is outlined. When determining carbon dioxide, effluent gas bypasses the carbon dioxide absorption tower before entering the analyzer. The carbon dioxide which it contains dilutes the oxygen remaining in the gas. The magnitude of this dilution can be used to calculate the percentage of carbon dioxide produced in terms of the air flow to the fermentor. Equipment required to alternately measure and record oxygen consumption and carbon dioxide production is described.

    Notes: Cobamide production by Butyribacterium rettgeri Barker and Haas (ATCC 10825) was studied on a laboratory scale. Yields of the order of 5 μg./ml. were obtained when this anaerobe was grown for 6 days at 37°C. in a medium containing glucose, cornsteep liquor, cobalt nitrate, calcium carbonate, and sufficient ammonium hydroxide to keep the pH between 6.0 and 7.2. All of the vitamin was found associated with the bacterial cells, and examination of extracts of these cells showed the presence of 5,6-dimethylbenzimidazolylcobamide coenzyme in large quantities. Supplementation of the fermentation medium with a number of benzimidazoles resulted in formation of traces of “new” cobamides with these bases in the nucleotide protion of the cobamide. Supplementation with a number of purines did not result in incorporation of these moieties in the cobamide portion of the molecule.

    Notes: Removal of the pungent factor, allyl isothiocyanate, will partly determine whether mustard seed can become a commerical source for oil and meal in the United States. In processing studies at the Northern Laboratory, the mustard glucoside was converted enzymatically and the pungent oil was removed. This process has now been extended to pilot-plant scale by using filtration-extraction equipment at the Southern Laboratory. After desolventization and further steam stripping, the extracted meal had a residual content of 2.9% crude fat and 0.004% allyl isothiocyanate.

    Notes: Bacillus subtilis NRRL B-2612, isolated at this laboratory, was used to produce polyglutamic acid from devitalized wheat gluten. Conditions for production of the polypeptide were investigated. When NRRL B-2612 was grown on wheat gluten in shaken flasks with phsophate buffer and salts at pH 6.5, yields of polymer reflected a 25-40% incorporation of glutamic acid into polyglutamic acid. Repeated alcoholic precipitation yielded peptides containing between 45 and 90% D-glutamic acid. Physical and chemical properties of a typical purified polyglutamic acid indicated that the product was a gamma-linked polypeptide composed of 75% D-glutamic acid and 25% L-glutamic acid with a molecular weight of approximately 200,000.

    Notes: The distribution of dissolved oxygen in agitated, sparger-aerated aqueous solutions has been investigated by polarographic techniques. The results of the investigations are discussed in relation to earlier studies in bubble distribution in such systems. Liquid-phase mixing is good at agitation intensities well below that necessary to disperse bubbles throughout the liquid.Suspended solids interfere with the transfer of oxygen unless they are freely suspended. Discrete fibers (paper-pulp) are much easier to suspend than molds in either filamentous or pellet forms. Mass-transfer at the cell-liquid interface appears to be unaffected, in both bacterial and mold suspensions, by the intensity of agitation, provided that the organisms are freely suspended.

    Notes: Microbial polysaccharides which have many potential industrial applications are receiving more and more attention. One of the economic obstacles to the commercialization of these polysaccharides has been the cost of isolating them from fermented broth. To reduce this cost a recycling process was developed. The polyanionic polysaccharide synthesized from glucose by the activity of the bacterium Xanthomonas campestris NRRL B-1459 is precipitated from the fermented broth with a quaternary ammonium compound (QAC).QAC is removed from the precipitate with methanol leaving the water-soluble polysaccharide. Evaporation of the methanol wash removed the methanol and substantially all the QAC was recovered in the concentrate. This was recycled for subsequent precipitations. Chemical assay and the viscosity of water solutions of the isolated polysaccharide indicate no adverse effects on it from recycled QAC. The cost to make this polysaccharide by the described procedure is estimated to be $1.14/lb. This cost estimate includes land, buildings, raw materials, equipment, labor and supervision, utilities, factory supplies, working capital, and plant overhead.

    Notes: A method of inoculating nutrient surfaces uniformly with bacterial cells has been developed. The method is based on controlled exposure of samples in a humidified chamber to a spray produced from a bacterial suspension. Factors affecting uniformity of inoculation (ionic strength of suspension, force of spray, distance between spray nozzle and sample, and exposure time) were studied in detail. Under optimum condition using agar medium in Petri plates, differences between total counts for six plates inoculated simultaneously, or between counts for individual 2 cm.2 areas taken at any location on any of the plates, were not statistically significant at the 5% level. The coefficient of variability for counts on 2 cm.2 areas renged from 8 to 12% between tests of 216 counts each.

    Notes: A number of factors was found to affect the cup plate assay for lysine with Streptococcus faecalis ATCC 6057. Hydroxylysine, aspartic acid, and Tween 80 were found to be among the essential components of the assay medium. Removal of any of these three components produced diffuse growth zones or otherwise unsatisfactory plates. The inclusion of asparagine and additional dipotassium phosphate to the medium was found to be advantageous but not an absolute requirement. It was important not to autoclave the hydroxylysine and the additional dipotassium phosphate together with the rest of the assay medium, but to add these components to the sterilized medium immediately before pouring the plates. With certain concentrations of hydroxylysine in the medium, the addition of L-glutamine was found to potentiate the effect of hydroxylysine and thereby improve the lysine plates. The effect of graded amounts of the above mentioned medium components and of the pH of the assay medium was also studied. Increasing the sterilization time of the medium from 5 to 10 min. at 120°C. improved the readability of the lysine plates and led to more easily reproducible results. Factors influencing the preparation of the inoculum for the lysine plates were also studied: the age of the stab culture, the amount of inoculum used per plate, and the influence of the nature of the suspension medium used for washing the inoculum.

    Notes: A sensitive cup plate assay method for lysine on large plates using S. faecalis ATCC 6057 as the test organism is described in detail. Well-defined zones of dense growth were obtained in a rectilinear dose - response range from 5 to 3000 μg. of L-lysine/ml. Comparative assays on twelve different samples were carried out using the turbidimetric tube assay method with Leuc. mesenteroides ATCC 8042 and the cup plate method with S. faecalis ATCC 6057. Good agreement between the two assay methods was obtained for five samples. For the remaining seven samples the tube assay values were appreciably higher than those obtained by the plate method. This discrepancy is discussed. Pure lysine added to various sample extracts could be quantitatively recovered. The specificity of the lysine requirement of S. faecalis ATCC 6057 in the plate assay was also investigated. Under certain experimental conditions, a weak and variable response was obtained with D-lysine and the polyamines cadaverine, spermine, and spermidine. There was generally no difficulty in distinguishing the D-lysine and polyamine growth zones from the L-lysine growth zones. This growth effect of D-lysine and polyamines could be diminished and even completely abolished by increasing the DL-hydroxylysine hydrochloride level in the plate medium. The lysine peptides glycyl-L-lysine and L-lysylglycine gave excellent growth zones of the same appearance as those produced by L-lysine.

    Notes: By growing Aspergillus parasiticus (C.M.I. 15957) under controlled conditions on sterilized peanuts an average of 265 mg. of aflatoxin per kilogram of peanuts has been produced and subsequently isolated. Other strains from the A. flavus-oryzae group gave lower yields of aflatoxin and one such strain gave aflatoxin from which certain normal components were absent. The aflatoxin produced on sterilized peanuts by any particular strain of A. flavus-oryzae was shown by thin-layer chromatography to contain the same major components as were produced by that strain on unsterilized whole peanuts.

    Notes: Shock pressure waves with a frequency of 50/sec. and a maximal pressure of 60-70 kg./cm.2 greatly reduced the viability of E. coli. A similar effect was obtained also on staphylococci, enterococci, Salmonella Zanzibar, and coliphages T2. On the contrary no effect on spores of B. subtilis was found. The effect was practically independent of the maximal pressure within the range from 30-80 kg./cm.2, the highest pressure tested. The effect decreased with increasing cell density of the bacterial suspension. Bacteria surviving shock treatment died considerably more rapidly when stored at 4°C. than bacteria treated in the same way except for exposure to pressure waves. Morphological examinations with the aid of ordinary light microscopy as well as electron microscopy suggest that the effect was due to mechanical action on the bacterial cell walls.

    Notes: It is a well-known fact that choosing a sequence of optimal control variables in each reactor tank of a multistage reactor system can result in a considerable increase of the desired product for a consecutive reaction system. The discrete maximum principle is applied to a generalized optimization problem of first order consecutive biochemical reaction system. A detailed numerical solution as an example is also presented for illustration.

    Notes: Ferrocyanide-treated beet molasses was fermented in fully baffled mechanically agitated, 2.5-liter, tank-type fermenters using pellets of Aspergillus niger grown in shake flasks as an inoculum. The object of the study was to adapt the fermentation method previously developed in an unstirred tower-type fermenter to a conventional tank-type fermenter. Under selected conditions of stirring (agitator speed 400-700 rpm) and sparging (medium porosity sintered disk), high yields of citric acid (8.6% citric acid, 70% conversion of available sugar) were obtained in 140 hr. of fermentation. There was little relation between citric acid yield and aeration conditions in the fermenter as judged by mash viscosity measurements and sulfite oxidation studies.

    Notes: A process has been developed giving over-all yields of about 50%: which could be increased to about 80% with higher material costs and processing time. The preferred method of recovering nucleotides from the cytoplasm has been thermal extraction by means of a heat exchanger followed by filtration, protein precipitation, and carbon adsorption. The concentrated eluate from the carbon is absorbed onto Dowex 1 ion-exchange resin, and groups of nucleotides are removed by pH-defined eluents and recovered by a second carbon adsorption. Finally, standard ion-exchange resolutions have been used to recover individual nucleotides. Other biochemicals in the extract have been investigated, and preliminary work has been done on the combination of nucleotide extraction with the recovery of nucleic acids from the residual cells.

    Notes: The metabolic pathway of degradation of naphthalene to salicylic acid has been studied by several investigators. The rates of conversion and of cell growth are the basis for the present study. In the early phase of the fermentation, the salicylic acid accumulation followed an exponential curve, as did the bacterial cell accumulation. In the second phase, most of the salicylic acid was produced according to a linear or zero reaction, at rates of 0.3 to 0.5 g./l./hr. A linear accumulation of microbial cell weight accompanied the linear salicylic acid formation. Despite the correlation of growth and salicylic acid production, the type or amount of nitrogen supplied for growth had only a small effect on yield over broad limits. The optimum pH for salicylic acid accumulation was approximately 6.5. Below this value a slower rate of production and lower final yield was seen. Above pH 6.5, a rapid degradation of salicylic acid was observed. A temperature range from 25 to 30°C. was optimum. At 35°C., no growth occurred, while at 20°C. very slow salicylic acid accumulation resulted.

    Notes: Sphaerotilus is usually present in biological waste treatment processes and is considered to be a nuisance organism because it may cause bulking of activated sludge. However, it may play an important role in the decomposition of putrescible organic matter in properly operated biological waste treatment processes. The research described herein is a study of the variety of types of organic compounds which may be decomposed by Sphaerotilus and the effect of some environmental factors upon the rate of decomposition. Although there are some types of compounds which cannot be decomposed by Sphaerotilus, it is shown that this organism is able to assimilate and oxidize a large variety of organic compounds and that it is tolerant of an extremely wide range of environmental conditions. The role of Sphaerotilus in biological waste treatment is discussed in the light of the data presented.

    Notes: Stabilization ponds have been widely accepted in recent years, following studies that established deeper understanding of the phenomena associated with the stabilization process. A compilation of information on the use of both sewage and industrial ponds is presented showing types and geographical location in the United States. A total of 1,304 stabilization ponds currently are used as the principal method of sewage treatment serving a population of 2,138,085. Ponds are used for tertiary treatment serving a population of 2,146,951, in 343 instances. Use of 827 industrial ponds by 31 industries in 44 States is also indicated. Indiana ranks first in usage with 159 ponds and Callfornia second with 140. Ponds were classed as effective by 66 percent of the 455 users who reported on this item. Of 149 reports on odors, 73% indicated nuisances. Insect problems were reported in only a small number of instances. Data are presented on design considerations and the mechanism of waste stabilization ponds. Aerobic ponds are given greatest emphasis. Photosynthesis and its dependence upon the algal mass, suitable temperature, incident light penetration, nutrient supply, and induced vertical mixing by wind are of prime importance in the stabilization mechanism. Odors are associated with prolonged anaerobic conditions, and these may persist up to 4 weeks following extended ice cover in cold climates, if BOD loadings are 25 lbs. per acre per day or greater. Nitrogen and carbon may be limiting factors in the development of an algal mass. Coliform, BOD, and nutrient removals are presented for various physical, chemical, and climatic conditions. Although fecal streptococci removal averaged 97% in a study pond, they were still discharged in the effluent at a rate of 700,000 per second in winter and 70,000 per second in summer. A striking similarity exists generally among the algal speciation in stabilization ponds, regardless of geographic location. The algal mass is, however, dependent upon unique pond conditions and location, and may vary upwards to nearly 5 million algal cells per milliliter, 34,000 p.p.m. by volume, or 30-35 tons per acre per year. The problem of blue-green algal mats and resultant pigpen odors in extremely localized areas is duscussed. Midges and midge larvae may have an impact on the nutrient cycle in a stabilization pond, and may pose a potential localized nuisance in some areas. Mosquito problems have usually been associated with growth of aquatic vegetation. Suggestions for minimizing the potential problem are discussed.

    Notes: Biological purification of water pollutants depends upon a complex balance of organisms and environment conducive to effective metabolism. The bench scale test is useful to determine effects of a given waste water on that balance and to suggest controls promoting optimum purification. Applicability of laboratory results depends, in part, upon an experimental design similating anticipated operating conditions. This paper discusses advantages and limitations of historical bench-tests as a guide for design of tests giving data that are more useful during full-scale operation.

    Notes: With the emphasis being given to the development of biologically soft detergents, it is necessary to establish eriteria defining biodegradability of these materials. It is the authors' opinion that a biologically soft detergent should have the following characteristics: (1) Under normal operations the material should be 85% removable by activated sludge. (2) Normally high discharges of the detergent should not influence biological activity. (3) The detergent should ultimately degrade to carbon dioxide and water.

    Notes: These experiments show that ABS can be adsorbed and desorbed from microbial cell surfaces. The adsorption equilibria between the free and adsorbed phases are primarily influenced by the pH of the system. The effects of ABS upon the biochemical activities of bacteria depended upon the amount of ABS adsorbed and the type of bacteria present. The behaviour of ABS is essentially the same whether in the presence of pure or mixed bacterial cultures. Two desorption experiments with soil from a reclaimed water spreading basin which has received sewage over a six month period showed that at least 82% of the ABS “loss” was recoverable from the soil. In all the experiments carried out in this study no evidence was obtained for the biochemical degradation of ABS.

    Notes: It has been found that a bacterium (isolant C12B) grew poorly on 6 and 8 carbon alcohols, well on 10 and 12 carbon alcohols, and slowly but well on the 14 to 18 carbon compounds. Unexpectedly, resting cells oxidized the 6 and 8 carbon compounds most readily and cell-free extracts oxidized 6, 8, and 10 carbon alcohols. Extracts from cells adapted to sodium lauryl sulfate oxidized the 12 carbon alcohol as well, if small concentrations of substrate were used. The bacterium grew on benzene sulfonate and adapted resting cells oxidized that compound. Pure culture degradation studies revealed that isolant C12B used only 11% of tetrapropylene ABS supplied as a sole carbon source, whereas 66% of sodium lauryl sulfate was degraded. Intermediate quantities of kerosene-based alkyl benzene sulfonate and a tallow-derived detergent were utilized. Extracts of another bacterium, TEG-5, grown on tetraethylene glycol, contained enzymes which oxidized polyethylene glycols up to an average molecular weight of 600, but not any larger polymers. This oxidation was visualized by coupling to reduction of ferricyanide.

    Notes: Because branched-chain alkyl benzene sulfonate (ABS) is well known to create water pollution problems in surface water and ground water, a study was made on the biodegradation of this surfactant along with other anionic and nonionic surfactants in detergents by water bacteria. Biodegradation was evaluated by the conventional river die-away test employing the methylene-blue method or surface-tension techniques as analytical tools. Under anaerobic conditions, sugar detergents (sucrose esters) seem to be an ultimate solution to water problems created by branched-chain ABS; in aerated water, straight-chain ABS, sulfo tallow methyl esters, and nonionic surfactants are preferable to branched-chain ABS to improve water problems.
