Abstract
The present invention is related to a recombinant microorganism optimized for the fermentative production of methionine and/or its derivatives, wherein in said recombinant strain, the methionine efflux is enhanced by overexpressing the homologous logous genes of ygaZ and ygaH genes from. It is also related to a method for optimizing the fermentative production of methionine or its derivatives comprising the steps of: a. culturing a recombinant microorganism wherein in said microorganism, the methionine efflux is enhanced by overexpressing the ygaZH homologous genes of ygaZ and ygaH genes from, in an appropriate culture medium comprising a fermentable source of carbon and a source of sulphur, and b. recovering methionine and/or its derivatives from the culture medium.
