Citrobacter koseri capable of degrading wastewater pollutants and application thereof

Abstract

The application provides a citrobacter koseri capable of degrading wastewater pollutants, which is a citrobacter koseri (C. Citrobacter koseri ) HG-01 isolated from paint spraying wastewater, and has a preservation number of CGMCC No. 34363. The application also provides application of the citrobacter koseri in treating wastewater containing toluene and / or xylene. The citrobacter koseri (C. Citrobacter koseri ) HG-01 obtained by screening and optimizing the culture conditions of the citrobacter koseri can significantly improve the degradation efficiency of xylene, and broaden the application range. The strain can grow in a culture environment with xylene as the only carbon source under the stress of organic solvents, can tolerate high-concentration xylene and has a degradation effect on xylene. Therefore, the strain can realize efficient, clean and secondary-pollution-free biological environmental remediation treatment effect, has the characteristics of low cost, simple operation, mild reaction conditions, energy saving, and provides a new strain resource for environmental pollution remediation.
