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- l,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:
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.
