Abstract: Comprende métodos para aumentar la produccion de un compuesto químico fino, por ejemplo, lisina a partir de un microorganismo, por ejemplo, Corynebacterium mediante la desregulacion de un gen codificador de una enzima, es decir, glicerol quinasa. Se proveen métodos para incrementar la produccion de lisina en Corynebacterium glutamicum a través del incremento de la expresion de la actividad de glicerol quinasa. También se provee un proceso para la produccion de lisina a través de la regulacion del flujo de carbono oxalacetato (OAA).Se proveen métodos para la produccion de lisina a través de la utilizacion de fructosa o sacarosa como fuente de carbono. Reivindicacion 1: Un método para aumentar el flujo metabolico a través de la vía de pentosafosfatos en un microorganismo que comprenda el cultivo de dicho microorganismo que contenga un gen que se desregula bajo condiciones tales que se aumenta el flujo metabolico a través de la vía de pentosafosfatos. Reivindicacion 49: Un microorganismo recombinante que comprende un gen de biosíntesis de pentosafosfato desregulado.

Abstract: 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 methionine synthase (metF) 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.
