Effect of vitamins and bivalent metals on lysine yield in Bacillus megaterium

IA Ekwealor, JAN Obeta

Abstract


The effects of vitamins and bivalent metals on lysine accumulation in Bacillus strains were investigated. Biotin enhanced lysine production in all the Bacillus strains, while folic acid and riboflavin stimulated lysine yields in Bacillus megaterium SP 86 only. All bivalent metals stimulated lysine
accumulation in B. megaterium SP 86 and B. megaterium SP 14, while Co2+ and Zn2+ improved lysine levels in all the strains.
