Abstract: The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., fructose-1,6-bisphosphatase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of increasing the expression of fructose-1,6-bisphosphatase activity. The invention also provides a novel process for the production of lysine by way of regulating carbon flux towards oxaloacetate (OAA). In a preferred embodiment, the invention provides methods for the production of lysine by way of utilizing fructose or sucrose as a carbon source.

Abstract: Method for fermentative production of at least one sulfur-containing fine chemical (I) by fermenting a (I)-producing coryneform bacterium (A); concentrating (I) in medium or cells, then isolating it. (A) expresses at least one heterologous nucleotide sequence (II) that encodes a protein (III) with O-acetylhomoserine-sulfhydrolase (metY) activity. An Independent claim is also included for preparation of a feed additive (B) that contains L-methionine by culturing/fermenting an L-Met producing microorganisms; removing water from the fermentation broth and optionally also up to 100% of the biomass, then drying the treated broth to recover (B) in powdered or granular form.
