Guangzhou pallor bacillus with high-efficiency degradation ability for pyridine

Abstract

The invention provides Ochrobactrum guangzhouense P2 with high capacity in degrading pyridine. The strain as a novel species of Ochrobactrum genus is obtained by separating and purifying sludge of oil and gas factories, and is preserved in China Center for Type Culture Collection with the preservation number of CCTCC M 207191. The strain has higher capacity in degrading pyridine, and can effectively degrade pyridine in sludge, thus lowering the sludge processing cost.

Description

technical field

[0001] The invention relates to the field of bacteria, in particular to a new strain of Cantonensis pallidum with high-efficiency degradation of pyridine. Background technique

[0002] As a typical refractory organic pollutant, the environmental problems caused by heterocyclic aromatic compounds have attracted more and more attention. Because most of them have "three effects", they are harmful to human health and ecological balance. At present, the diffusion of heterocyclic aromatic compounds in the environment has caused serious pollution of soil and groundwater. An effective method to solve such problems in bioremediation, the use of degrading microorganisms screened from the environment can effectively remove pollutants such as heterocycles and benzene rings in sludge and other environments.

[0003] Pyridine, as the most basic and typical heterocyclic aromatic hydrocarbon substance, has become the focus of research, especially focusing on the biodegradat...
