The present invention is related to a recombinant() strain optimised for the fermentative production of methionine and/or its derivatives, wherein in said recombinant strain, the methionine import is attenuated and the methionine efflux is enhanced. It is also related to a method for optimising the fermentative production of methionine or its derivatives comprising the steps of: a. culturing a recombinant microorganism wherein in said microorganism, the methionine import is attenuated and the methionine efflux is enhanced, 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.
