bactéria capaz de produzir ácido lático, e método para produção de ácido lático

摘要

The present invention provides: a lactic acid-producing Escherichia coli including an enzymatic activity of at least one NAD-dependent lactate dehydrogenase and an enzymatic activity of at least one NAD-independent lactate oxidoreductase, both of which are enhanced so as to decompose one of D-lactic acid or L-lactic acid and to produce the other one of D-lactic acid or L-lactic acid; and a lactic acid production method using the lactic acid-producing Escherichia coli.
