4361586 Vacuum enzymatic digestion of protein material
PATENT ABSTRACTS
Ist fermentation tank is recharged with a mash and the fermentation of the fermenting broth in the 2nd tank is continued under aeration while lowering the temperature of the fermenting broth in such manner that the final fermentation temperature does not fall below 18 degrees C. and the lowering temperature does not fall below 18 degrees C. and the lowering temperature does not become higher than the temperature once lowered.

4363875 PROCESS FOR PRODUCING L-TRYPTOPHAN, AND A PURE CULTURE OF A MICROORGANISM STRAIN USED IN SAID PROCESS Takeo Akashiba, Akira Nakayama, Atsuhiko Murata, Musashino, Japan, assigned to Showa Denko KK In a process for producing L-tryptophan which comprises cultivating an L-tryptophanproducing mutant of Bacillus subtilis under aerobic conditions in a nutrient culture medium containing anthranilic acid, a carbon source, a nitrogen source and a mineral source, and recovering the resultant Ltryptophan from the culture broth, the improvement wherein the mutant is a strain resistant to 5-fluorotryptophan and 8azaguanine; and a pure culture of a microorganism strain used in said process.
4362750 PRODUCTION OF FERMENTED TYPE SAUSAGE William E. Swartz, assigned to Stauffer Chemical Company
Disclosed is a dry or wet milling process for making fermentable sugars and high-protein products from starch bearing material, characterized by saccharification of the starch followed by recovery of fiber and other nonprotein materials and of destarched protein as separate products, leaving a sugar solution that is essentially free of insoluble materials. The sugars are fermented to ethanol and carbon dioxide by the action of added yeast. After fermentation, the yeast is recovered for use in fermenting additional quantities of sugars supplied either for batch or continuous processing. The alcohol is then removed leaving a dilute solution of unfermentable soluble materials, and this liquid, in whole or in part, is recycled to preceding steps in the process.

4359532 M E T H O D FOR GLUCOSE EXTRACTION FROM GREEN CROPS Melvin Brown, assigned to Aluminum Company of America An improved method suitable for extracting glucose from green crops, such as leaves, grasses, legumes, stems of green plants and tree leaves. 1he method comprises the steps of subjecting the green crops to a pulping action in an organic acid solution recirculated from a subsequent fermentation separation step to produce a pulp comprising a
protein-rich liquid and fibrous material, separating protein-rich liquid in the pulp from the fibrous material and separating protein from the protein-rich liquid by initiating anaerobic fermentation in an acidic solution thereby providing a concentrated protein fraction suitable for preservation and an acidic solution. At least a portion of the acidic solution is recycled to the separation step, the recycling of the solution being provided for purposes of washing the fibrous material to remove residual protein therefrom. The fibrous material is then subjected to hydrolysis with at least one material selected from the group consisting of mineral acids and enzymes to permit increased recovery of glucose.
4359530 PROTEIN EXTRACTION FROM GREEN CROPS Melvin H. Brown, assigned to Aluminum Company of America A method of extracting protein from green crops such as leaves, grasses, legumes, stems of green plants and tree leaves is disclosed. The method comprises the steps of subjecting the green crops to a pulping action in an acid solution recirculated from a subsequent anaerobic fermentation step to produce a pulp comprising a protein-rich liquid and fibrous material. The protein-rich liquid in the pulp is separated from the fibrous material. The protein is separated from the protein-rich liquid by anaerobic fermentation in an acidic solution thereby providing a concentrated protein fraction suitable for preservation and an acidic solution at least a portion of which is recycled to insure further removal of protein from the fibrous material.
