Description

technical field

[0001] The invention belongs to the technical field of biodegradation treatment of polluted soil and water, in particular to a plant degrading bacteria. Background technique

[0002] Polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons, PAHs) are a class of condensed ring compounds containing two or more benzene rings arranged in linear, angular or clustered shapes, with hydrophobicity, low solubility, low vapor pressure, High melting point and boiling point, high octanol-water partition coefficient and other characteristics. Polycyclic aromatic hydrocarbons have strong carcinogenic, teratogenic and mutagenic effects. Generally speaking, low-molecular-weight PAHs with 2-3 rings have significant acute toxicity, while some high-molecular-weight PAHs have potential carcinogenicity. Due to the presence of conjugated large π-bond electron systems in PAHs molecules, they have high stability, their photolysis and biodegradation are slow, and they ca...
