The present invention relates to use of inducible promoters in the production of methionine by fermentation.The present invention concerns amethod for the production ofmethionine, its precursors or derivatives in a fermentative process comprising the following steps: -culturing a modified microorganism in an appropriate culture medium comprising a source of carbon, a source of sulphur and a source of nitrogen, and -recovering methionine and/or its derivatives from the culture medium, wherein in said modified microorganism, the expression of at least one gene involved in methionine production is under the control, direct or indirect,ofaheterologous inducible promoter. The invention also concerned the modified microorganism used in the method. |
