PROBLEM TO BE SOLVED: To provide a lactic acid bacterium of which growth at low temperature is improved by transformation.SOLUTION: Provided is a method for improving growth ability of lactic acid bacterium under a low temperature culture condition, i.e., 10°C or lower, by transforming a lactic acid bacterium with a plasmid enabling high expression of peroxiredoxin so that the bacterium can proliferate and produce peroxiredoxin at low temperature, where the plasmid is constructed by introducing a highly expressible peroxiredoxin gene of a specified base sequence. Also provided is a low temperature proliferating lactic acid bacterium that amply expresses peroxiredoxin as a result of the transformation. |
