| Abstract: | A study is made on the method for breeding mutant strain of metabolic regulation. Corynebacterium beijinese Q-72 is taken as starting bacterial strain. After mutagenizing by UV, the authors have screened the mutant strain UH62 which grows well on the medium with succinate as unique carbon source and shows strong carboxylation. The mutant strain UH62 shows respectively a glutamate productivity of 1.45% higher and a glutamate/glucose conversion rate of 9.1% higher than those of starting strain Q-72. |
