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 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.

主权项

1. A method for producing methionine, comprising:
1) preparing a reaction solution that includes a methionine precursor which is an O-acetyl homoserine or an O-succinyl homoserine, an enzyme which has the activity of converting the methionine precursor into methionine, and a mixture of methyl mercaptan and dimethyl sulfide; and 2) performing an enzymatic conversion reaction while stirring the reaction solution.
