The invention discloses bacillus megaterium and application thereof in degrading pyrethroid insecticides. The degrading strain is Bacillus megatherium (Bacillus megatherium) strain HLJ7, which is preserved in Guangdong province microorganism strain preservation center in 2019, 9, 4 days, and the preservation number is GDMCC No. 60760. The invention discloses the degradation effect of bacillus megaterium on pyrethroid insecticides such as allethrin for the first time, and the high-efficiency and rapid degradation strain HLJ7 is obtained by screening. Based on the invention, the bacillus megaterium has obvious biodegradation effect on pyrethroid insecticides such as allethrin, has high degradation efficiency and stable degradation performance, can tolerate higher-concentration pesticides, and can be used for bioremediation of polluted environments such as water and soil polluted by pyrethroid insecticides such as allethrin. The invention provides a new development approach for breaking the bottleneck of controlling pesticide residue pollution, enriches the germplasm resource library of pesticide degrading bacteria, and has wide application prospect. |
