Abstract

The invention discloses a Sphingobium yanoikuyae and an application thereof in degrading polycyclic aromatic hydrocarbon. The Sphingobium yanoikuyae provided by the invention is named as LD29 with the strain collection number of CGMCC No.4400. The Sphingobium yanoikuyae LD 29 can grow and breed by respectively taking phenanthrene, anthracene, fluoranthene and pyrene as the only carbon source and energy source under the aerobic condition. In addition, the Sphingobium yanoikuyae LD 29 has a degrading effect on mixed polycyclic aromatic hydrocarbon, especially on pentacyclic benzopyrene [alpha] in the mixed polycyclic aromatic hydrocarbon. The Sphingobium yanoikuyae can be used for repairing soil and the water body polluted by the polycyclic aromatic hydrocarbon, and is quick, convenient and environmentally-friendly, and can be used for reducing the content of the polycyclic aromatic hydrocarbon in the environment, thereby providing new microorganism resources for bioremediation for polycyclic aromatic hydrocarbon pollution, and having an important value for environmental governance as well as considerable economic benefit and good social benefit.

Description

technical field

[0001] The invention belongs to the technical field of biological treatment of environmental pollutants, and relates to a strain of Sphingobacterium yanoguchi and its application in degrading polycyclic aromatic hydrocarbons. Background technique

[0002] Polycyclic Aromatic Hydrocarbons (PAHs for short) are aromatic hydrocarbons containing two or more benzene rings. At room temperature, pure polycyclic aromatic hydrocarbons are solid, and their overall characteristics are high melting point, high boiling point, and low water solubility. The water solubility of polycyclic aromatic hydrocarbons decreases with the increase in the number of benzene rings, and their bioavailability and degradability It also decreases and stays in the environment for a long time.

[0003] PAHs come from nature and human activities. Polycyclic aromatic hydrocarbons are a type of organic matter that exists in nature. They can be synthesized by some algae, plants, and degrading bac...
