| Abstract: | Summary The strainCorunebacterium glutamicum ATCC 21513 grown in a medium containing 17.5% glucose, 5.5% ammonium sulphate and 2% yeast extract was found to produce (under laboratory conditions) high amounts of L-Lysine in this optimized medium. Lysine production, residual sugar and dry cell mass were measured as a function of fermentation time. It was observed that l g of cell mass produced 2.96 g of Lysine. The conversion efficiency was found to be 44%. |
