    摘要： Substances producing an undesired odor and taste can be removed from microbial protein materials if these materials are treated with aqueous solutions which contain a phosphate and/or a hydrophilic low molecular weight aliphatic compound which contains at least two functional groups from the series comprising hydroxy, formyl, keto and carboxy. Preferred aliphatic extraction auxiliaries are flavoring acids, sugars and polyols, and phosphates are orthophosphates and diphosphates. The extraction can also be carried out in association with reducing the nucleic acid content of defatted cell aggregates.

    摘要： A cofactor having an aromatic or benzylic amino group is converted into an isothiocyanate by reaction with a compound such as thiophosgene and the isothiocyanate of the cofactor is attached to a polymer which is preferably water-soluble. When the polymer has amino groups, a thiourea bridge is formed between the polymer and cofactor and a polymer having hydroxyl groups results in a thiocarbamate bridge. The polymer may be a copolymer of vinylamine or vinylmethylamine and vinylmethylacetamide, partially alkylamine-substituted .alpha., .beta.-poly-(2-hydroxyethyl)-D,L-aspartamide, polyethyleneimine or carbohydrate. The cofactor bound to a polymer and an enzyme are contained in microcapsules or in a membrane to form an enzyme reactor.

    摘要： In the process for the preparation of 4-benzyl aspartate starting from dibenzyl aspartate and/or its salts only one benzyl group is selectively removed by catalytic hydrogenation. By setting up appropriate reaction conditions elimination takes place mainly of the benzyl group on the C.sub.1 atom of the compound. The desired product can be isolated from the reaction mixture by precipitation.
