Abstract

Process for the production of l-valine by fermentation, characterized in that a mutant layer of corynebacterium glutamicun is cultivated, the growth of which is subject to a concerted inhibition by the mixture of cysteic acid l-valine or the mixture of cysteic acid l-threonine in a fermentation medium containing at least one assimilable source of carbon and at least one assimilable source of nitrogen, and the nutritive organic and mineral constituents necessary for the development of the microorganism.
