使用NTG为主要诱变剂,对出发菌株E.coliW31101进行多次连续的诱变和筛选,使其酶法合成色氨酸的产量由45g/l上升至695g/l。
Taking NTG as main mutagenic agent,A good strain with the productivity of L tryptophen reachint to 69.5 g/l was abstained from the original strain Escherichia coli W3110 1,by continuous induced mutation and selection in the enzymetic synthesis test.
