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: 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 authors describe continuous cultivations of Escherichia coli possessing high penicillin-acylase activity in corn-steep liquor, peptone, and ammonium phenylacetate containing nutrient medium. If the cultivation is performed in the absence of ammonium phenylacetate the enzymic activities of cells from the batch as well as the continuous cultures are very low. The enzymic activity of cells in the batch process was considerably increased by the addition of 0.015% ammonium phenylacetate to the nutrient medium. Further increase of ammonium phenylacetate concentration did not result in any further increase of acylase activity. Continuous cultivation of the bacteria at the above ammonium phenyl-acetate concentration was unsuccessful, as the enzymic activity of the bacteria constantly decreased during the process. On increasing the concentration of ammonium phenylacetate in the medium to 0.15% the authors succeeded in maintaining the enzymic activity of the bacteria at the same level as in the batch process performed at 0.015% concentration, throughout the whole continuous cultivation. At the dilution rate D = 0.5 hr.-1 the concentration of cells in the culture effluent from the fermentor at the steady state was equal to cell concentration at the end of batch cultivation. In relation to the cultivation time the output of cells in continuous cultivation is almost seven times higher as compared with the batch process.

Notes: Steam-sterilizable membrane probes for monitoring the dissolved oxygen level in fermentors, or the oxygen content of gas streams, are described. The probes have a silver cathode, a lead anode, and an acetate buffer as an electrolyte. The membrane is Teflon. The current output of the probes in the absence of oxygen is negligible.
