20120123158 | Method for Increasing Methionine Productivity Using a Mixture of Methyl Mercaptan and Dimethyl Sulfide - 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. | 05-17-2012 |
20120136058 | Method For Increasing The Solubility Of Methionine By Mineral Addition And Acid Treatment - The present invention relates to a method for enhancing the solubility of methionine. More particularly, the present invention relates to a method for increasing the solubility of methionine, in which mineral and sulfuric acid are added at an appropriate ratio to enhance the methionine solubility, thereby overcoming the problem of low solubility of methionine in water. | 05-31-2012 |
20130273614 | NOVEL O-ACETYLHOMOSERINE SULFHYDRYLASE OR MUTANT PROTEIN THEREOF, AND METHOD FOR CONVERTING TO METHIONINE USING THE SAME - The present invention relates to a novel protein having O-acetylhomoserine sulfhydrylase activity, a mutant protein thereof, a polynucleotide encoding the same, a recombinant vector comprising the polynucleotide, a microorganism transformed with the recombinant vector, and a method for producing methionine or acetic acid using the protein. The production method of the present invention has the advantage of producing L-methionine and acetic acid cost-effectively through having higher conversion rate and reduced reaction time compared to the existing methods, and it can minimize the amount of enzyme homogenate added when using the mutant protein, thereby easily producing L-methionine and acetic acid at high yield. | 10-17-2013 |
