METHOD FOR PRODUCING LACTIC ACID FROM PLANT-DERIVED RAW MATERIAL, AND LACTIC-ACID-PRODUCING BACTERIUM

摘要

The present invention provides: a lactic acid-producing Escherichia coli comprising at least one gene of a sucrose non-PTS gene group, including at least a sucrose hydrolase gene, provided that a combination of a repressor protein (cscR), a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) and a combination of a sucrose hydrolase (cscA), a fructokinase (cscK) and a sucrose permease (cscB) are excluded, wherein the lactic acid-producing Escherichia coli comprises a lactic acid production enhancing system provided by genetic recombination; and a lactic acid production method including producing lactic acid from a plant-derived sucrose-containing raw material by using the lactic acid-producing Escherichia coli.
