Abstract:
1. 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 the fructose metabolism ability improvement system is enhancement of phosphorylation ability derived from fructose-1-phosphate kinase activity or the fructose metabolism ability improvement system is enhancement of fructose uptake ability in a fructose metabolism pathway derived from inactivation or attenuation of innate FruR activity of the
