    摘要: The present invention relates to a method 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 sulphur. The microorganism and/or the culture medium and/or the process parameters were modified in a way that the accumulation of the by-product N-acyl-methionine (NAM) is reduced. The isolation of methionine or its derivatives from the fermentation medium is also claimed.

    摘要: The present invention concerns a new method for the biological preparation of a diol comprising culturing a microorganism genetically modified for the bioproduction of an aliphatic diol, wherein the microorganism comprises a metabolic pathway for the decarboxylation of a hydroxy-2-keto-aliphatic acid metabolite with an enzyme having a 2-keto acid decarboxylase activity, the product obtained from said decarboxylation step being further reduced into the corresponding aliphatic diol, and wherein the microorganism is genetically modified for the improved production of said hydroxy-2-keto-aliphatic acid metabolite.The invention also concerns a modified microorganism for the production of an aliphatic diol.
