核黄素产生菌的原生质体诱变选育

Protoplasts Mutagenesis of Strains Producing Riboflavin

用紫外线对核黄素产生菌的原生质体进行诱变选育获得一株核黄素的高产突变株其核黄素发酵单位较出发菌株提高66%

The experiment discussed in this paper shows that a lot of mutants were screened from protoplasts by using ultra violet mutagenesising and Riboflavin produced by the mutant E.a 3.increased by 66% .
