The invention provides a Rhodococcus ruber capable of degrading phthalates and an application thereof. The bacterium is YC-YT1, and the preservation number is CGMCC No.13959, which can degrade 85% of 100 mg / L bis(2-ethylhexyl) phthalate contained in inorganic salts within 12 hours, and within 5 days Can degrade 100mg / L bis(2-ethylhexyl) phthalate, dipropyl phthalate, butyl benzyl phthalate contained in inorganic salt culture medium 100%; Phthalates are also highly degradative. The Rhodococcus rubrum YC-YT1 of the present invention has a wide tolerance range for salt ion concentration, pH and temperature, can be applied to bioremediation and industrial wastewater treatment of environmental pollution caused by phthalates, and has good economic value and application prospects.

The invention discloses a strain of Rhodococcus rhodochrin capable of efficiently degrading fenvalerate and application thereof. The present invention takes microbial resources in the traditional fermentation process as the research object, screens and obtains the degrading bacteria for fenvalerate that is used more in the planting process of tobacco and other crops, has a large residual amount, and has a long degradation cycle. Microbacterium esteraromaticum E20 strain, derived from Fenjiu Daqu, has high safety and can efficiently degrade 5mg / kg of fenvalerate. It has a certain application prospect in the degradation of low-concentration fenvalerate pesticide residues in crops such as tobacco leaves. In order to improve the quality and safety of tobacco products and solve the problem of pesticide residues in tobacco leaves and other crops, it provides a safe and effective biodegradation pathway.

The invention relates to a multi-strain composition for high-efficiency degradation of organic phosphorus pesticides in the environment, which consists of a strain A, a strain B and a strain C, wherein the strain A is rhodococcus rhodochrous R-D3 strain; the B strain is stenotrophomonas acidaminiphila G1; and the C strain is cupriavidus taiwanensis X1 strain. The strain A, strain B and strain C are inoculated onto and cultured in a Luria Broth (LB) liquid culture medium respectively to form bacterial solution A, bacterial solution B and bacterial solution C; the bacterial solution A, bacterial solution B and bacterial solution C are uniformly mixed according to a volume mixing ratio of (1-2):(1-2):(1-2); and thus, the multi-strain composition for high-efficiency degradation of organic phosphorus pesticides in the environment is obtained. The multi-strain composition can quickly degrade organic phosphorus pesticide residue to different degrees within 1 to 7 days, the degradation rate of the multi-strain composition reaches over 95 percent, and the pollution of organic phosphorus pesticides is eliminated effectively.
