Embodiment Construction
[0010] The strains were extracted from river mud and cultured, and the continuous acclimatization method with high concentration of polycyclic aromatic hydrocarbon phenanthrene as the only carbon source lasted for one month; with six different organophosphorus pesticides OP-DDT, PP-DDE, PP-DDD , PP-DDT, methyl parathion and parathion were re-screened, and strains with high tolerance to organophosphorus pesticides were selected. The number is CGMCC 6900.

The invention discloses bacillus megatherium capable of degrading polycyclic aromatic hydrocarbon and application thereof. The bacillus megatherium has the collection number of CGMCC 6900 and is preserved in China General Microbiological Culture Collection Center. The bacillus megatherium has high long-term tolerance and degradation capacity in high-concentration polycyclic aromatic hydrocarbon, and the defects of low environmental tolerance in actual lab strain application at present can be solved.
Description
technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a Bacillus megaterium that can be used for environmental protection and an application thereof. Background technique [0002] Polycyclic aromatic hydrocarbons (PAHs) organic compounds account for more than one-third of more than 1,000 environmental carcinogens. PAHs in the environment mainly come from coal combustion, petroleum cracking, and wastewater from industrial production. Due to the extremely slow natural degradation rate, the accumulation of polycyclic aromatic hydrocarbons in the environment continues to increase with industrial development, which poses a great threat to national health. In recent years, cases of carcinogenicity and teratogenicity caused by polycyclic aromatic hydrocarbons are common, and the degradation and treatment of polycyclic aromatic hydrocarbons have become an important issue in today's environmental strategy. Due to its high...
