Abstract

To improve the yield of lysine by the isolate, auxotrophic mutants were isolated. Among the mutants, only one auxotrophic mutant required vitamin B12. This mutant producedα-alanine. About 200 mutants resistant to the lysine analog S-(2-aminoethyl)-l-cysteine were isolated and some of them produced well above the wild type.
