SINGLE-CELL PROTEIN-QUALITY PRODUCED FROM LIGNOCELLULOSIC MATERIALS BY THE ASCOMYCETE CHRYSONILIA-SITOPHILA (TFB-27441 STRAIN)

Data are presented for amino acid contents of fifteen carbohydrates, l ignocellulosic materials, including olive milling waste water. The sel ected substrate were: glucose, cellobiose, saccharose, microcrystallin e cellulose, tannin, phlobaphene, bark, lignocellulose residue, sugar residue from organosolv process, rice hull, irradiated rice hull, oran ge bagasse, alpechin (5%), alpechin (10%) and irradiated alpechin (10% ). Ratios of some amino acids of nutritional significance in conventio nal protein sources and those induced by different lignocellulosic sub strate are presented. Also, a comparison of the ratios of individual a mino acids to total essential amino acids (A/E ratio) and total essent ial amino acids to total amino acids recovered as nitrogen (E/T ratio) , together with essential amino acid chemical scores, led us to compar e the quality of each carbon source used. These analyses showed that o range bagasse, alpechin (10%) and bark were the most inexpensive mater ials and produced the highest protein qualities.
