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 APPROPRIATERATIOTO 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.
