Metabolic Engineering for L-Lysine Production by Corynebacterium glutamicum
Corynebacterium glutamicum has been used since several decades for the large-scale production of amino acids, esp. L-glutamate and L-lysine. After initial successes of random mutagenesis and screeening approaches, further strain improvements now require a much more rational design, i.e. metabolic engineering. Not only recombinant DNA technology but also mathematical modelling of metabolism as well as metabolic flux analysis represent important metabolic engineering tools. This review covers as state-of-the-art examples of these techniques the genetic engineering of the L-lysine biosynthetic pathway resulting in a vectorless strain with significantly..
