ABSTRACT
In order to obtain higher L-lactic acid yield industrial strain, the original strain Rhizopus oryzae PW352 was mutated by means of N+ ions implantation and a mutant strain Rhizopus oryzae RE3303 was obtained. Its lactic acid yield was increased by 75% than that of the original one. The acid producing condition was optimized by orthogonal design. The concentration of L-lactic acid reached to 131~136g/L and the conversion rate of glucose was as high as 86%~90% under the optimum condition.
