| Abstract: | After chemical mutagenizing , the glulamate -producing bacterial metabolic passway was changed The mutant strain B4 grew on the mediunl with glycerol, amber acid and aldehyde acid as carbon source was selected. The mutant strain B4 showed a glutamate productivity of 11.1% higher and a glutamate/glucose conversion rate of 8.7% higher than those of starting strain BI. |
