Abstract

The present invention disclosed a neighboring germinated bacteria and its application.The neighboring vitamin degradation OX5 provided by the present invention belongs to Pseudomonas SP. It is located in a typical cultivation center in China. The storage date is June 29, 2015, and the preservation number is CCTCC NO: M2015415.The bacteria is the Gram -negative bacteria. The colonies are round and slightly convex. The colonies are milky white, yellow in the middle, and the surface is moist and smooth.The bacteria can use neighbors as the only carbon source for growth and reproduction. When pure cultivation, the degradation rate of 48H to 1500mg / L neighboring t atr is as high as 98%, and the tolerance concentration of neighboring toluene reaches 2500mg / L.This bacteria can not only degrade the neighboring dysfamer and other benzene in the coking wastewater, but also reduce the COD in the coking biochemical water, which is used for biological reinforcement treatment of coking wastewater and has a wide application prospect.

Description

technical field

[0001] The invention belongs to the technical field of environmental pollutant bioaugmentation, and in particular relates to an o-xylene degrading bacterium and its application. Background technique

[0002] Ortho-xylene is an important organic chemical raw material, mainly used in the production of phthalic anhydride, dyes, pesticides, paint solvents and drugs, etc., of which about 90% is used to produce phthalic anhydride, 2% is used to produce solvents, and only 1% Used to produce dye intermediates. O-xylene is highly toxic, and can irritate the skin and mucous membranes at low concentrations, and can penetrate into the body through the skin; at high concentrations, it can anesthetize the central nervous system and make people unconscious. Long-term exposure can affect liver and kidney function and cause neurasthenia syndrome. Using physical and chemical methods to treat o-xylene can achieve good results, but the cost is high and it is easy to cause seco...
