Abstract

The invention relates to metribuzin pesticide residue-degrading bacteria; the degrading bacteria are named as bacillus cereus N1 (Bacillus cereus N1) by classification, and are Gram-positive bacteria; a preservation number of the degrading bacteria in China Center for Type Culture Collection (CCTCC) is CCTCC NO: M2011163. Soil bioremediation microorganism prepared by the degrading bacteria and application are also disclosed. The metribuzin pesticide residue-degrading bacteria are bacterial strains which are obtained from sludge in a water spout of a insecticide factory for producing metribuzin and have strong degradation capacity to the metribuzin; the bacterial strains are grown by utilizing the metribuzin as exclusive nitrogen source; and thallus activity is increased by metribuzin induction in a liquid culture medium so as to improve the degradation capacity to the metribuzin. The microorganism provided by the invention is characterized by simple preparation method, relatively low cost and convenient implementation and can be dispersed on soil; degradation effect in the soil can reach to 68.19%; therefore, the microorganism has good application prospect.

Description

technical field

[0001] The invention belongs to the field of biological technology, and specifically relates to a metrizone pesticide-degrading bacterium and a soil bioremediation bacterial agent prepared based on the bacterium, which uses microbial technology to degrade chemical pesticide residues, and is suitable for green and pollution-free agricultural products in modern agricultural production production and processing. Background technique

[0002] Mecitrione is a triazine herbicide developed by German Bayer in 1971, mainly used in soybean fields to control broad-leaved and gramineous weeds. This type of herbicide has the advantages of fast weeding speed and low toxicity to humans and animals. However, due to long-term use or improper use, it is easy to cause phytotoxicity to sensitive crops, which not only affects the growth of higher plants, but also affects the surface, groundwater, soil and animals. Certain hazards. Some of them, such as azimidone, remain in the ...
