Abstract

The invention discloses an endosulfan degradation stain and application thereof in soil remediation. The endosulfan degradation stain is a strain LD-6 of Stenotrophomonas rhizophila, is preserved in China general microbiological strain preservation administration center On March 2, 2012, and the preservation number is CGMCC No.5839. The endosulfan degradation stain can realize the complete degradation of 100 mg / L of endosulfan within 10 days under an aerobic condition and has low-toxic or non-toxic degradation products and fast environmental degradation; the strain LD-6 is sensitive to common antibiotics, such as tetracycline and kanamycin and tolerant to 13 tested heavy metals and can inhibit the growth of a plurality of phytopathogens; and the endosulfan degradation stain has capability of efficiently degrading the endosulfan in an actual soil environment, can outstandingly shorten the degrading time of the endosulfan and has practical application significance and value.

Description

technical field

[0001] The invention belongs to the technical field of biological treatment of environmental pollutants, and in particular relates to a bacterium for efficiently degrading endosulfan and its application in soil environmental pollution restoration. Background technique

[0002] As an important means of agricultural production, pesticides play an extremely important role in protecting agricultural production, improving comprehensive agricultural production capacity, promoting stable grain production and increasing farmers' income. China is not only a big producer of pesticides, but also a big user of pesticides. The annual usage and average usage are about 1.2 million tons and 2.34 kg / ha respectively, ranking first in the world. However, the utilization rate of pesticides is only 10-20%, and the rest all enter the soil, water and atmosphere, causing serious pollution. According to statistics, there are about 13-16 million hectares of farmland polluted by pesti...
