Abstract

The invention discloses high-efficiency organic pollutant carbendazim degrading bacteria and use thereof. The organic pollutant carbendazim degrading bacteria are (mycobacterium sp.)DJL22, and were collection in China General Microbiological Culture Collection Center, and the collection number of organic pollutant carbendazim degrading bacteria is CGMCC No.5041. When the (mycobacterium sp.)DJL22 CGMCC No.5041 is cultured in inorganic salt culture medium for 5 days, the rate of degradation of carbendazim at a concentration of 100mg / L reaches 84.79 percent; and when the (mycobacterium sp.)DJL22CGMCC No.5041 is cultured in inorganic salt culture medium for 15 days, the rate of degradation of carbendazim at a concentration of 600mg / L reaches 62.77 percent. Therefore, the stain can efficiently degrade carbendazim and has a bright application prospect in repairing soil polluted by carbendazim.

Description

technical field

[0001] The invention relates to a bacterium for efficiently degrading organic pollutant carbendazim and its application. Background technique

[0002] The chemical name of carbendazim is N-(2-benzoimidazolyl)-methyl carbamate, and the English chemical name is methyl benzimidazol-2-ylcarbamate. Molecular formula is C 9 h 9 N 3 o 2 , the structural formula is as follows.

[0003]

[0004] Carbendazim can interfere with the process of nucleic acid synthesis and cell mitosis, and has the effect of preventing and controlling fungal diseases of various crops. It is currently the main fungicide for preventing and controlling plant diseases in agriculture. It has a wide range of applications and mainly acts on rice, peanuts, cotton, and tobacco. , beets, and a variety of vegetables, can prevent melon powdery mildew, tomato early blight, bean anthracnose, blight, rape sclerotinia, green onions, leek gray mold, eggplant, cucumber sclerotinia, melons, bean anthr...
