The Nutritive Value of Yeast Protein.*
The idea of the use of yeast as a source of food protein for man and the higher.animals is not a new one; it has, however, been given renewed emphasis by the exigencies of the food situation during the war. Yeast is a highly nitrogenous by-product of the fermentation industries which heretofore has been largely wasted. It also presents the possibility of a synthetic production of protein from e...
متن کاملComposition and nutritive value of yeast biomass and yeast protein concentrates.
Yeast biomass (Saccharomyces sp.) produced in local breweries as a by-product was utilized in this study. Percent proximate composition, amino acid composition, and protein nutritive value were determined for the yeast cell biomass (YC), a sodium perchlorate extracted and isoelectrically precipitated protein concentrate (P-PC), and a sodium trimetaphosphate treated extract followed by isoelectr...
متن کاملPURIFICATION AND PROPERTIES OF AN EXTRACELLULAR PROTEASE PRODUCED BY PENICIUIUM EXPANSUM
Penicilliurn expamum grown in a medium with rice husk as a carbon source produced an extracellular protease. The protease enzyme was isolated from culture broth by fractionation with acetone and column chromatography on Sephadex G- 100 and DEAE A-50. The protease enzyme was purified about 17.47 fold, with a recovery of 14%. The purified protease was homogenous on SDS polyacrylarnide disc ge...
متن کاملSome Properties of Extracellular Acetylxylan Esterase Produced by the Yeast Rhodotorula mucilaginosa.
The red yeast Rhodotorula mucilaginosa produced an esterase that accumulated in the culture supernatant on induction with triacetin. The enzyme was specific for substrates bearing an O-acetyl group, but was relatively nonspecific for the rest of the molecule, which could consist of a phenol, a monosaccharide, a polysaccharide, or an aliphatic alcohol. The esterase was more active against acetyl...
متن کاملExtracellular enzymes produced by marine eukaryotes, thraustochytrids.
Extracellular enzymes produced by six strains of thraustochytrids, Thraustochytrium, Schizochytrium, and Aurantiochytrium, were investigated. These strains produced 5 to 8 kinds of the extracellular enzymes, depending on the species. Only the genus Thraustochytrium produced amylase. When insoluble cellulose was used as substrate, cellulase was not detected in the six strains of thraustochytrids...
