Abstract
The production of lysine by Bacillus megaterium SP‐14 and Bacillus circulans Tx‐22 using agricultural by‐products as carbon and nitrogen sources was assessed. Among the carbon substrates used were potato, sorghum, plantain, millet, yam, cassava, and corn starches, while the nitrogen sources include cowpea, bambara‐nut, cotton seed, groundnut, soybean, and blood meals. The effect of natural nitrogen sources (1.0% w/v) and synthetic nitrogen source (4.0% w/v (NH~4~)~2~SO~4~) on lysine production by the Bacillus strains showed that natural nitrogen sources gave better lysine yields.
