Abstract
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 a appropriate ratio to O-acetyl homoserine or O-succinyl homoserine and to an enzyme having an activity of converting methionine precursor into L-methionine, so as to perform an enzyme reaction, to thereby improve the conversion rate of L-methionine and organic acid from the L-methionine precursor, and thus increasing L-methionine yield as compared to conventional method.
