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.
L-Tryptophan and L-phenylalanine auxotrophic mutant strains of the genus Bacillus(芽孢杆菌属 L-色氨酸和 L-苯丙氨酸辅助突变菌株)能够在含有足以抑制母菌株生长的间氟苯丙氨酸和/或肉桂酸的培养基上旺盛生长,通过一般常规水培养基的有氧发酵产生的 L-苯丙氨酸比迄今为止最好的 L-苯丙氨酸生产相关微生物产生的 L-苯丙氨酸更多。
