The invention discloses a Methylophaga strain for online monitoring of heavy metals and application thereof, wherein the Methylophaga strain is selected from the estuary of Guangdang river in Yantai, Shandong, and is an obligate aerobic bacterium, aerobic respiration and oxygen consumption of which having good response sensibility to the two heavy metal ions, Pb2+ and Hg2+; Pb2+ and Hg2+ can inhibit strongly the respiratory action of the Methylophaga strain. The Methylophaga strain is collected under CGMCC No. 13058. The Methylophaga strain and the application thereof have the advantages thatquick response and early warning can be achieved for the heavy metal ions, Pb2+ and Hg2+, in drinking water, surface freshwater and sea water by monitoring changes in oxygen consumption rate, responding speed is high, and operating is simple; the Methylophaga strain can be cultured automatically with no need for the supply of mass bacteria lyophilized powder, and the cost is lower; the Methylophaga strain has an excellent application prospect in real-time online monitoring of heavy metals, research and development of warning technical instruments and other aspects.
