Abstract

The invention discloses Pseudomonas nitroreducens and application thereof, belonging to the field of environmental microorganism. The Pseudomonas nitroreducens CQ1 of the invention is derived from the sewage of oxidation ponds in the sewage treatment system of Beijing Yanshan Petrochemical Co., Ltd., and obtained by enriching, separating and purifying. The Pseudomonas nitroreducens CQ1 is cultured and collected in the China General Microbiological Culture Collection Center (hereinafter referred to as CGMCC) with the collection number being CGMCC No.3159. The invention further discloses the application of Pseudomonas nitroreducens in the biodegradation of quinoline or derivatives thereof. Quinoline or derivatives thereof with the concentration reaching 700mg / L can be degraded by Pseudomonas nitroreducens of the invention, and the degradability can reach 100% after treating for 72h. Moreover, the Pseudomonas nitroreducens CQ1 of the invention is sensitive to kanamycin sulfate, tetracycline and gentamicin and does not carry plasmids.

Description

technical field

[0001] The invention belongs to the field of environmental microorganisms, and in particular relates to a strain of pseudomonas nitroreductor and its application in biodegrading quinoline or its derivatives. Background technique

[0002] Quinoline (also known as azanaphthalene) is a typical representative of nitrogen-containing heterocyclic compounds, and it is also the basic structural unit of a large number of complex nitrogen-containing heterocyclic compounds. Quinoline and its derivatives are widely found in natural products such as coal tar, mineral oil, creosote, fossil fuels and plant alkaloids, and are also important refractory organic compounds in various industrial wastewaters such as coking wastewater, rubber wastewater, and pharmaceutical wastewater polluting ingredients. Because of their high water solubility, these compounds have become common pollutants in soil and groundwater, especially near solid waste landfills, steel mills and fossil fuel...
