    摘要: The invention relates to a bacterial process for producing L-tryptophan, L-tyrosine or L-phenylalanine. The process utilizes a coryneform glutamic acid-producing bacterium being capable of producing L-tryptophan, L-tyrosine or L-phenylalanine and also decreased or lacked in phosphoenolpyruvate carboxylase activity. The mutant strain is then cultured in order to accumulate the amino acid in a medium and the amino acid is recovered therefrom.
