ABSTRACT:
The present invention features methods of increasing the production of a fine chemical, e.g., lysine from a microorganism, e.g.,Corynebacteriumby 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 inCorynebacterium glutamicumby 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.
