Abstract: The invention is directed to an unsintered spherical adsorbent particle composition having high mechanical strength and controlled pore size distribution, comprising finely divided silica hydrogel particles bonded together with a silica or metal oxide sol.

Abstract: Natamycin biomass comprising 5-60% natamycin, most preferably 25-60% natamycin, and methods for forming the biomass, are disclosed. The natamycin biomass can be mixed with compatible carrier to form a premix comprising 0.2-5% natamycin. The premlix may be mixed with animal feed to form an animal feed mixture comprising cracked grain and 1.1-110 ppm of natamycin.

Abstract: The present invention is directed to methods for the production of ascorbic acid by culturing organisms of the genus Prototheca and recovering ascorbic acid from the fermentation medium.

Abstract: A non-biocidal method for inhibiting microbially influenced corrosion of susceptible metal surfaces having an anaerobic biofilm containing active sulfate-reducing bacteria comprising contacting the biofilm with a liquid dispersion of anthraquinone compound.

Abstract: Anthraquinone compounds inhibit methane production by methanogenic bacteria in the rumen of ruminant animals, increasing production of volatile fatty acids and feed utilization efficiency. Preferred anthraquinones are unsubstituted anthraquinone, 1-aminoanthraquinone, 1-chloroanthraquinone, 2-chloroanthraquinone, 2-chloro-3-carboxyanthraquinone, 1-hydroxyanthraquinone, and 9,10-dihydroanthraquinone.

Abstract: Microalgal biomass that comprises cells of Chlorella pyrenoidosa which contain greater than 2.0% by dry weight of L-ascorbic acid (Vitamin C), microorganisms and processes that form the biomass, and L-ascorbic acid enhanced animal feed compositions that contain the biomass are disclosed.

Abstract: A method of inhibit sulfide production in a media containing sulfate-reducing bacteria is disclosed. The method comprises adding particles of a finely divided sulfide production-inhibiting anthraquinone to the medium. The particles have a particle size of 0.1 to 2.5 microns, preferably 2 to 0.1 microns.

Abstract: Cis-dihydrodiol compounds of the formula ##STR1## where n is 0 or 1 (preferably 0) are produced by the microbial oxidation of a diphenylaceylene compound of the formula ##STR2## using a mutant of a Pseudomonas bacteria at 25.degree. to 35.degree. C. and pH 6-8. The cis-dihydrodiol compound is in turn treated with an aqueous solution of a base to produce a corresponding 3-hydroxydiphenylacetylene compound or with an aqueous solution of an acid to produce a corresponding 2-hydroxyacetylene compound. The mutant strain is preferably Pseudomonas ATCC 55272.

Abstract: Lactobacillus delbrueckii sub-species bulgaricus ATCC-55163, a strain of Lactobacillus delbrueckii sub-species bulgaricus that can produce essentially stereoisometrically pure L-(+)-lactic acid, and a process for producing essentially stereoisometrically pure L-(+)-lactic acid using the strain are disclosed. A method for producing a mutant strain of Lactobacillus that produces essentially stereoisometrically pure lactic acid is also disclosed.

Abstract: A process for producing a product with an intensified beer flavor is disclosed. The process comprises: steeping barley with water to produce steeped-out barley; treating the steeped-out barley with an enzyme promoter; preferably gibberellic acid; germinating the steeped-out barley to produce a green malt; heating the green malt to 70-89 C. for 0.5 to 3 hours while maintaining the moisture content of the green malt at 30-55 weight percent; drying the heated green malt to produce dried malt, the dried malt having a moisture content of 3.5-5.5 weight percent; making a mash from the dried malt by grinding and adding brewing water, thus producing a wort and a residue; separating the wort from the residue; boiling the wort to produce boiled wort; cooling and pitching the boiled wort with yeast to produce pitched wort; and fermenting the pitched wort to produce the product with an intensified beer flavor.

Abstract: The protection of food products from contamination by food pathogens, particularly Listeria monocytogenes, by incorporation of 6 to 50 ppm and preferably 6 to 15 ppm of beta-acids, as extracted from hops, into such food products.

Abstract: A natamycin producing Streptomyces species ferments to produce natamycin. A spore suspension of the Streptomyces species is propagated in a predetermined medium to obtain a quantity of Streptomyces cells. The Streptomyces cells ferment in a predetermined production medium having a controlled pH to produce a recoverable amount of natamycin.
