One of the mutant strain B. flavum AJ/SA-315 showing maximum lysine activity was selected after screening. Yeast sludge was fermented by this mutant strain of B. flavum to increase the lysine content. Maximum lysine concentration of about 57.2 mg/100 mL was achieved with 2 % corn steep liquor. The amino acid profile of final microbial biomass protein showed that it was enriched with all essential amino acids. Fermentation of yeast sludge with mutated B. flavum AJ/SA-315 enhanced the lysine content from 1.59 % to 3.71 %. The fermented samples can be a good source of lysine and other essential amino acids for use in synthetic feed.
