1. A method of degrading a chlorinated hydrocarbon pollutant with Stenotrophomonas maltophilia GYH, comprising: adding cells obtained by large-scale cultivation of Stenotrophomonas maltophilia GYH to an inorganic salt medium with a pH of 5-8; adding the chlorinated hydrocarbon pollutant; and culturing the cells at 20-35° C. while shaking at 140-180 rpm to degrade the chlorinated hydrocarbon pollutant, wherein the Stenotrophomonas maltophilia GYH is preserved in China Center for Type Culture Collection with the preservation number CCTCC NO: M 20191025.
