METHOD FOR INCREASING METHIONINE PRODUCTIVITY USING A MIXTURE OF METHYL MERCAPTAN AND DIMETHYL SULFIDE

摘要

The present invention relates to a method for increasing L-methionine productivity and organic acid productivity. More particularly, the present invention relates to a method which involves adding a mixture containing methyl mercaptan and dimethyl sulfide at an appropriate ratio to O-acetylhomoserine or O-succinylhomoserine, and to an enzyme having an activity of transforming methionine to conduct an enzyme reaction, to thereby enhance the transformation rate from an L-methionine precursor into L-methionine and organic acid, and thus increasing L-methionine yield rate as compared to conventional methods.
