Method for quickly screening extractable petroleum hydrocarbon degradation bacteria, and application of method

The invention discloses a method for quickly screening extractable petroleum hydrocarbon degradation bacteria, and application of the method, is used for processing petroleum hydrocarbon pollutants inoil extraction wastewater, and belongs to the technical field of petroleum water environment pollution repairing. Three typical extractable petroleum hydrocarbons (tetradecane, hexadecane and hexacosane) in a water body are selected as target pollutants, and a control group takes glucose as a carbon source and an energy substance, which can be easily utilized. By use of 2, 6-DCPIP (dichlorophenolindophenol sodium) color development reaction and a culture growth curve, the tolerance and the degradability of a culture for the petroleum hydrocarbon pollutants can be judged. Bacteria screening time required by the method disclosed by the invention is short, a quantity of medicaments used in an experiment is small, and an operation is simple. The petroleum hydrocarbon degradation bacteria canbe quickly screened, and a
