Abstract: A broth medium for the identification of Escherichia coli. The medium employs coumaric acid, preferably para-coumaric acid, to inhibit growth and metabolic activity of other gram negative microorganisms and thus eliminate false positive test results in a medium designed for E. coli organisms.

Abstract: A process for the production of crab analogue meats from wheat gluten is disclosed. Meat material of finely fibriform structure typical of crab meats is produced by blending reducing agent and foaming agent with wheat gluten, and thereafter subjecting the resulting blended material to gelation with heat and stirring.

Abstract: L-Aspartic acid is produced by culturing an L-aspartic acid producing mutant strain which is resistant to 6-(dimethylamino)-purine and which is derived from a parent strain belonging to the genus Brevibacterium or Corynebacterium in an aqueous culture medium and then recovering the L-aspartic acid which accumulates in the aqueous culture medium.

Abstract: A shaped protein food product comprising edible textured protein particles bound together by heat-set soybean protein isolate.

Abstract: Disclosed herein is a diagnostic agent for determining the .alpha.-amylase content of a sample comprising a first compound selected from the group consisting of maltotetraose, maltopentaose, and maltohexaose; and a second component comprising an appropriate glucose detecting reagent, such as glucose oxidase or glucose dehydrogenase.

Abstract: A feed supplement for ruminant animals is provided comprising a lower alkyl ester of a biologically -- useful amino acid other than methionine or a salt thereof, or a lower alkyl ester of a biologically -- useful ester of a hydroxy analogue of a biologically -- useful amino acid other than methionine or a salt thereof.

Abstract: High protein, low calorie dairy spread water-in-oil emulsions having a 20-65% aqueous phase are produced employing as the aqueous phase a protein concentrate having a 13-20% protein content and obtained as a by-product in the manufacture of butter from sour buttermilk, buffered at 6-7 with citrate and phosphate buffering salts, and as the fat phase butter oil optionally mixed with a polyunsaturated vegetable oil, emulsifying the aqueous phase into the fat phase at 38.degree.-50.degree. C., flash pasteurizing the emulsion, optionally adding flavoring agents before or after emulsifying and pasteurization, and then cooling the emulsion, first to 20.degree.-14.degree. while working the emulsion as it solidifies, and then to storage temperature, e.g., 12.degree.-8.degree. C.

Abstract: Antibiotic U-51,640 produced by the controlled fermentation of the microorganism Streptomyces ficellus Dietz, sp. n., NRRL 8067. This antibiotic and its acid addition salts are active against Gram-positive and Gram-negative bacteria. Accordingly, they can be used in various environments to eradicate or control such bacteria.

Abstract: A method for producing a substance highly containing high content of maltose therein, by saccharifying a liquefied starch with amylase produced by streptomyces at the same time with or after treatment with .beta.-amylase.

Abstract: New antibiotic substances are obtained by culturing a strain belonging to the genus Streptomyces and by recovering said substances from the culture material. The new antibiotic substances possess insecticidal and acaricidal properties.

Abstract: 2-Keto-L-gulonic acid is prepared directly from D-glucose by microbial conversion utilizing mixed culturing on or mixed contacting with a medium containing D-glucose, employing at least two kind of microorganisms; 2,5-diketo-D-gluconic acid producing strains which belong to the genera of Acetobacter, Acetomonas and Gluconobacter and strains capable of converting the 2,5-diketo-D-gluconic acid into 2-keto-L-gulonic acid which belong to the general of Brevibacterium and Corynebacterium. Both the incubation of the microorganisms in a medium containing D-glucose and the direct contact of any products obtained from the cells of the microorganisms with the substrate may be used in the disclosed process.

Abstract: A method for characterization of biological activity comprising providing a plurality of gas-tight cells each having a light-permeable wall section, each cell containing a different .sup.14 C-labeled fermentable substrate, a carbon dioxide absorber and a scintillation compound in intimate proximity to each other remote from said substrate, and an axenic sample of a biologically active material; subjecting said cells to conditions conducive to biological activity and thereafter measuring the light emitted by the scintillation compound as a result of the decay of .sup.14 CO.sub.2 generated by the metabolic action of the biologically active agent in said sample on said substrate and captured by the carbon dioxide absorber. Apparatus is provided comprising a plurality of sterile chambers containing different .sup.

Abstract: The invention relates to a process for the production of citric and osocitric acids by a culture of a diploid Candida Lipolytica yeast in a nutrient medium containing substances which are sources of carbon, nitrogen, and mineral compounds, the medium containing thiamin in a concentration in excess of 200 micrograms per liter.

Abstract: Method for preventing moulding or other microbial surface deterioration of foods and feeds due to micro-organisms by using a preservative substance, either a chemically defined food additive or a vegetable extract having microbicidal or microbe-inhibiting effect. The preservative is applied in the form of an aerosol in which a substantial part of the particles or droplets in the aerosol have a diameter less than 5 microns, preferably within the limits 0.2-2 microns. The aim of the present invention is to reduce the economic losses and health risks caused by mould formation and other microbial surface growth on food materials and articles and feeds.
