Production of microbial protein from forest products

Evaluation of single cell proteins produced by Chrysonilia sitophila (TFB-27441 strain) with tannin, phlobaphene, bark and lignocellulosic material from Pinus radiata D. Don was made. The amino acids content and its quality were measured by their ratios of individual amino acids to total essential amino acids (A/E ratio) and total essential amino acids to total amino acids (E/T ratio). The values obtained were similar to those of egg and casein proteins. The same trends in the chemical scores were observed. The results of this study indicate that amino acids profiles obtained using bark components as substrates underwent some modification, but in general the obtained proteins could be considered as of excellent quality.
