Method of producing L-phenylalanine by fermentation, and bacteria therefor.

摘要

L-Tryptophan and L-phenylalanine auxotrophic mutant strains of the genus Bacillus which are capable of vigorous growth on culture medium containing enough of m-fluorophenylalanine and/or cinnamic acid to suppress growth of the parent strain produce more L-phenylalanine by aerobic fermentation of generally conventional aqueous media than the best L-phenylalanine producing related microorganisms available heretofore.
