Abstract

Solid-state fermentation of spent grains into fungal single-cell protein (SCP) using Chaetomium cellulolyticum gave a final product of 25.12%, 23.74%, and 23.39% crude protein for substrate subjected to 1% (w/v) NabI pretreatment, steam pretreatment at atmospheric pressure for one hour, and no treatment, respectively. Addition of nutrient1s did not give significant effects on the production of protein rich biomass. The maximum protein production of the SCP products was on the fifth day and decreased rapidly after the eighth day despite the increased level of reducing sugar. Crude fiber content increased in the final SCP products of five-day fermentation owing to the presence of undegraded cellulose plus lignin. The amino acid composition of SCP shows higher than those of the FAO standards except for methionine, cystine and tryptophan.
