| Abstract: | After chemical mutagenizing , the Lysine production bacterial metabolic pass was changed. The mutant strain B10, which grows on the medium with glycerol, Homoserine and Alanine, is selected as carbon source. The glutamate productivity and the glutamate conversion rate of mutant strain B10 are 18.097% and 15.56% respectively, higher than those of the starting strain B1. |
