Stenotrophomonas pavankii and application of stenotrophomonas pavankii in dye wastewater treatment

The invention discloses stenotrophomonas pavankii and application thereof in dye wastewater treatment, and belongs to the technical field of dye wastewater treatment. According to the invention, a strain of stenotrophomonas pavanii GXUN74707 is obtained through separation, and the preservation number of the strain is CGMCC (China General Microbiological Culture Collection Center) No. 27475. Tests show that the highest flocculation rate can reach 99.0% when a kaolin solution is treated by fermentation liquor of the strain; the strain fermentation liquor is used for treating dye wastewater containing Congo red, and the dye decolorization rate is 95.6%. The stenotrophomonas pavankii provided by the invention has a good application prospect in the aspect of dye wastewater treatment, not only has an excellent flocculation effect, but also can effectively remove dyes in the dye wastewater, and is green and environment-friendly. 本发明公开了一株帕万氏寡养单胞菌及其在处理染料废水中的应用，属于染料废水处理技术领域。本发明分离得到了一株帕万氏寡养单胞菌(Stenotrophomonas pavanii)G
