    Notes: A newly developed method for washing membranes and the adhesive strength of mandarin orange juice fouling on reverse osmosis membranes were studied. When the permeation rate decreased, it was restored to more than 90% of its original value by a lateral surface flushing of highly accelerated mandarin orange juice driven by the expansion force of compressed gas. For runs of 4–5 hr duration with 10° Brix feed, the normal operating cycle was 45 min of reverse osmosis concentration followed by a 10-sec wash. Membranes treated at higher temperature have a more condensed surface from which deposits are easily removed. However, high axial flow rates, which are useful for preventing the fouling on the membrane, actually promote permanent fouling.

    NATURE OF THE DEPOSIT ON REVERSE OSMOSIS MEMBRANES DURING CONCENTRATION OF PECTIN/CELLULOSE SOLUTIONS (1979)

    Notes: Model solutions consisting of varying concentration of the major fouling components of mandarin orange juice, pectin and cellulose, were studied. The deposits were scraped from the membranes and analyzed for weights and concentrations of pectin and cellulose. Suspensions of cellulose with no pectin caused no decrease in permeation flux, but large declines in permeation flux occurred during concentration of solutions of pectin and cellulose. Weights and concentrations of both components in the deposits changed with altering operating conditions and decreased with increasing mean flow velocity. Resistance of the deposit to water permeability (Rg) was related to the concentration of solute at the membrane surface (Cg) by the empirical equation, Rg =α Cg1.7 (α= constant). Accumulation of deposit on the membrane was in two forms: viscous layer and film layer. The former was a common form of deposit accumulated during the concentration of model solution under all conditions, but the latter was formed only under conditions at higher permeation flux with modelately high mean flow velocity. The film layer was insoluble in water but soluble in 0.0N HCl solution.

    Studies on the pathogenesis of streptococcal infection in cultured yellowtails Seriola spp.: effect of the cell free culture on experimental streptococcal infection (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish diseases 2 (1979), S. 0

    Notes: Abstract. A previous paper has revealed that experimental streptococcal infection was associated with a rapid growth of the intestinal bacteria, suggesting association of the condition with an exotoxin. The present study was undertaken to see the effect of the exotoxin on the streptococcal infection by administering cell free culture before the bacterial challenge. Cell free culture of Streptococcus sp. strain YT-3 was inoculated intramuscularly at a dosage of 0–5 ml per 100 g body weight 1 h prior to bacterial challenge. Three fish were killed at intervals after challenge for viable counting of bacteria in the viscera and blood. Intramuscular inoculation with either low virulent or virulent bacteria alone at dosages of 106 to 107 cells did not produce the disease in the fish, with almost complete clearance of the bacteria from the viscera and blood within 120 h. When the exotoxin was inoculated intramuscularly prior to the bacterial challenge, however, either low virulent or virulent bacteria at 106 to 107 cells could produce fatal infection with prominent streptococcal clinical signs.

    Studies on the pathogenesis of streptococcal infection in cultured yellowtails Seriola spp.: the fate of Streptococcus sp. bacteria after inoculation (1978)

    Notes: Abstract. The causative agent of streptococcal infection of yellowtails has been isolated but no information is presently available with respect to the mechanism of infection. The present study deals with the growth of the bacteria in the fish body at various periods after either per-oral or per-cutaneous challenge with Streptococcus sp. YT-3 strain at different passage levels. After percutaneous challenge with bacteria of high virulence, the kidneys retained the bacteria with the relatively high count of 107 cells per gram of tissue while in other organs, although high concentrations of 105-106 cells were detected in 10 min, this was followed by a progressive decrease up to 24 h post-inoculation with a subsequent rapid increase during the later stages of the disease process. The highest rate of growth was obtained in the intestine, where 107 cells were detected at 72 h after inoculation. After oral challenge, the bacteria were detected at high levels from organs and blood within 10 min but they were completely removed from all organs except the intestine within 24 h.

    Notes: SUMMARY— The water-extractable soybean proteins (WESP) were fractionated into five fractions by gel filtration with Sephadex G-200 column. Four of the five fractions were protein fractions, while the fifth fraction was nonprotein fraction. The first two fractions were heterogeneous by sedimentation analysis, while the third and fourth fractions give homogeneous fractions with 7s and 2s respectively. The trypsin inhibitor activity was found only in the fourth fraction.

    Notes: Polysaccharide 13140, a curdlan-type polysaccharide produced from a culture filtrate of Alcaligenes faecalis var. myxogenes strain NTK-u, has the unique property of forming a gel on heating. This polysaccharide is composed of β-1,3 linked glucose residues. When heated, aqueous suspension of the polysaccharide forms an elastic gel which is thermally irreversible, heat stable and acid stable. The texture properties of the polysaccharide gel lie in between agar-agar gel and gelatin gel. Potential applications of the polysaccharide in food processing are quite diverse and promising because it can improve such properties as viscoelasticity, palatability, binding quality, water holding capacity, heat stability and compatibility

    Notes: For the rapid identification of additives such as antioxidant, ultraviolet absorber, and slipping agent, polypropylene containing such additives was heated in a tube connected directly to the inlet system of a mass spectrometer. The vapor of the additives evaporating out of the polypropylene was led to the reservoir and then submitted to mass spectrometry to give spectra for identification.

    Notes: Nuclear magnetic resonance absorption spectra of linter cellulose containing various amounts of water were studied to clarify the relation between the amount of absorbed water in cellulose fiber and the molecular motion in such a cellulose-water system. An amorphous cellulose sample was used for the sake of comparison. The changes in line width and second moment of the spectra were measured at various temperatures. From the variation with temperature of the first-derivative curves and the second moments, it has been inferred that the proton movement of absorbed water changes markedly over the approximate range 180°-200°K and that the absorbed water lowers the glass transition temperature of cellulose to room temperature.
