Microorganism Producing L-Methionine Precursor and Method of Producing L-Methionine and Organic Acid from the L-Methionine Precursor

摘要

The present invention relates to a method for producing L-methionine, comprising: i) culturing an L-methionine precursor-producing microorganism strain in a fermentation solution, so that the L-methionine precursor accumulates in the solution; and ii) mixing a converting enzyme and methylmercaptan or its salts with at least a portion of the solution to convert the accumulated L-methionine precursor into L-methionine, as well as to microorganism strains used in each step.
