Bacterium for fermenting L-tryptophan from mixed saccharum and fermentation method thereof
The invention relates to the field of microorganisms, and in particular relates to a bacterium for fermenting L-tryptophan from mixed saccharum and a fermentation method thereof. The Enterobacteriaceae bacterium for producing L-tryptophan can have the capability of simultaneously utilizing hexose and pentose to produce the L-tryptophan because of containing the coding gene of a cAMP receptor protein mutant. The cAMP receptor protein mutant is obtained through mutating one or a plurality of amino acid loci of the cAMP receptor protein. The bacterium provided by the invention consumes glucose and xylose in a culture medium containing the glucose and the xylose at the same time, and the yield and conversion rate of the L-tryptophan are increased.
