Aumento del rendimiento de la metionina

摘要

The invention is related to a process for the production of methionine or its derivatives by culturing a microorganism in an appropriate culture medium comprising a source of carbon and a source of sulfur. The microorganism is modified in such way that the methionine/ carbon source yield is increased, in particular the modified microorganism presents a decreased deformylation of formyl-THF. The isolation of methionine or its derivates from the fermentation medium is also described.
