Bacillus pumilus capable of degrading atrazine efficiently

Abstract

The invention provides bacillus pumilus capable of degrading atrazine efficiently and relates to bacillus capable of degrading the atrazine efficiently. The bacillus pumilus is bacillus pumilus gy 201401 and preserved in Common Microorganism Center, China Committee for Culture Collection of Microorganisms, the preservation address is No. 3, yard No. 1, Beichen West Rd, Chaoyang District, Beijing City, the preservation date is 29th, Dec, 2014, and the preservation number is CGMCC No. 10252. The bacillus pumilus belongs to a type of microorganisms which are great in stress resistance, the degradation of atrazine residual in soil is accelerated obviously after the bacillus pumilus is applied, harm of the atrazine residual to next crop of sensitive crops is alleviated or avoided, thereby the crop output is increased, and higher economic benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, in particular to the discovery of a bacillus capable of repairing atrazine-contaminated soil. Background technique [0002] Atrazine belongs to the triazine herbicides and is a selective systemic conduction pre-emergence and post-emergence herbicide. It has been widely used in my country in recent years, but it is a long-acting herbicide with a long residual time. It is easy to cause pollution to the ecological environment, and its residues will cause serious phytotoxicity to the subsequent sensitive crops, which is an important problem in agricultural production and the ecological environment. In recent years, there have been frequent incidents of atrazine harming sensitive crops (beets, melons, wheat, soybeans, etc.) in recent years, directly causing serious economic losses. [0003] Microorganisms are biological groups with strong ability to degrade organic pollutants. Since 1982, scho...

AI Technical Summary

Problems solved by technology

[0004] With the deepening of people's research on the degradation of atrazine by microorganisms, some problems have gradually emerged. For example, in the laboratory, the degradation effect of microorganisms on atrazine is very good, but the expected effect cannot be achieved in the environment, and even Contrary to laboratory effects; toxicity issues of secondary products of microbial degradation, etc.
