摘要： A method is provided for culturing a microorganism in a culture medium containing a carbon source and an electrolyzed water containing not more than 0.4 ppm chlorine produced during electrolyzing water containing an electrolyte in an electrolytic cell. The culture medium may also contain a carbon source and an acidic water having a pH value of 1-4 and a redox potential from 800 mV to 1500 mV. The acidic water is obtained by electrolysis of water in an electrolytic cell. Further, the culture medium may contain a carbon source and an alkaline water having a pH value of 10-13 and a redox potential from −1000 mV to 800 mV. The alkaline water is obtained by electrolysis of water in an electrolytic cell. The redox potential for the alkaline water is determined by the use of a platinum electrode as a working electrode and a silver-silver chloride electrode as a reference electrode. The microorganism may be selected from Escherichia coli, strain J1, strain JM2N, or an artificial recombinant. The microorganism can decompose a pollutant, such as phenol, toluene, cresol, trichlorethylene and dichloroethylene.
