PROCESS FOR THE CONVERSION OF STARCH AND PROTEIN-CONTAINING CELLULOSIC SUBSTANCES INTO NUTRIMENTS RICHER IN PROTEINS

摘要

ABSTRACT OF THE DISCLOSUREProcesses for the conversion of starch and protein containingcellulosic substances such as cereals, bran from cereal and flourmills and broken pieces and crumbs of essentially fat-free bakedgoods from bakeries into nutriments richer in proteins by dispers-ing in water the cellulosic substances containing starches and pro-teins in comminuted form, subjecting the resulting slurry of thecellulosic substance in water to hydrolysis to convert the starchestherein to glucose or other fermentable sugars, separating theglucose-containing liquid from the remaining solids by ultrafiltra-tion, aerobically cultivating in the said glucose-containing liquida yeast such as Candida utilis or a bacterium that ferments andutilizes glucose for growth and subsequently recovering from thefermented liquid the protein-containing yeast or bacterium that wasgrown therein for use as a protein concentrate in human nutritionor as a supplement for animal feeds.-1-
