Growth of Candida tropicalis 2838 cells on straw hydrolyzates.
Improved strain of Candida tropicalis 2838 grows on nonseparated straw hydrolyzates with no addition of vitamins and trace elements at a specific growth rate mu = 0.34 and 44% yield coefficient (referred to reducing substances). The reducing substances in hydrolyzates contain predominantly monosaccharides (xylose, glucose, arabinose, mannose). Cells grown in this way are rich in proteins (62%) and essential amino acids (lysine, phenylalanine, leucine, threonine and valine). The product obtained under industrial conditions by fermentation of the nonseparated hydrolyzates contains 8--9% of proteins and it is a suitable supplement of fodder mixtures for monogastric domestic animals. Nutrition tests on rats and pigs indicated that this product can substitute the hay-flour, and, partially, blood-flour barley, and that the strain used is nonpathogenic.
