METHODS FOR THE PREPARATION OF A FINE CHEMICAL BY FERMENTATION

摘要

The present invention features methods of increasing the production of a fin e chemical, e.g., lysine from a microorganism, e.g., Corynebacterium by way of deregulating an enzyme encoding gene, i.e., lactate dehydrogenase. In a preferred embodiment, the invention provides methods of increasing the production of lysine in Corynebacterium glutamicum by way of the expression of lactate dehydrogenase 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 method s for the production of lysine by way of utilizing fructose or sucrose as a carbon source.
