摘要： The present invention relates to a method for producing L-methionine using a bio-synthesis process and a specific enzymatic process. More particularly, the present invention relates to a method for producing L-methionine with high yield by enzyme conversion reaction from L-methionine precursor in the presence of methyl mercaptan (CH3SH). The process of the present invention enables selective production of L-methionine which may be used in various fields of industry, such as feed- and food-additives, as raw material for medical supplies, pharmaceutical drugs, and the like.

摘要： The present invention relates to a method for preparing methyl mercaptan, in batches or continuously, preferably continuously, said method including at least the following steps: a) reacting at least one hydrocarbon feedstock in the presence of hydrogen sulphide (H
2 S) and optionally sulphur (S) such as to form carbon disulphide (CS
2 ) and hydrogen (H
2 ); b) reacting said carbon disulphide (CS
2 ) by hydrogenation in the presence of said hydrogen (H2) obtained in step a) such as to form methyl mercaptan (CH
3 SH), hydrogen sulphide (H
2 S) and possibly hydrogen (H
2 ); c) optionally recirculating said hydrogen sulphide (H
2 S) formed during step b) to step a); and d) recovering the methyl mercaptan.
