Problems solved by technology

In the prior art, our research group already has an invention patent for degrading bacteria (ZL96106317.3, publication number: CN1145408A, publication date: March 19, 1997), which is a strain of Bacillus J5, which can effectively degrade methylamine Phosphorus, but the strain has a narrow degradation spectrum and can only degrade one pesticide, methamidophos, so its use is limited

Embodiment Construction

[0018] Examples of the present invention are described below.

[0019] Activate the original seed of the microbial organophosphorus pesticide residue-degrading bacteria BTAH1 of the present invention on a petri dish, measure its degradation performance, and inoculate it on the inclined surface of a test tube for later use. The test tube seeds were inoculated into 1000ml shake flasks containing 200ml broth medium, cultured with constant temperature shaking until logarithmic phase, and prepared to inoculate seed tanks. 500 liters of seed tanks, 400 liters of feeding capacity, the medium formula is: glucose 0.8%, (NH 4 ) 2 SO 4 1%, K 2 HPO 4 0.2%, MgSO 4 0.05%, NaCl 0.01%, CaCO 3 0.3%, yeast extract 0.02%, pH 7.2-7.5. After the feeding is completed, 121°C high-pressure damp heat sterilization, after cooling to 33°C, inoculate the above-mentioned cultivated shake flask strains into a 500-liter seed tank according to the inoculum amount of 10%, and cultivate to the logar...

Abstract

The invention provides a degrading bacterial agent for eliminating triazine herbicide residues, the bacterial strain used is Gram staining positive bacteria BTAH1, which is identified as Exiguobacterium sp. The main biological characteristic is G + , the bacteria are irregular rod-shaped, 0.7-1.2×2.0-4.0μm in size, without flagella, facultative anaerobic; positive for catalase; negative for oxidase; able to hydrolyze starch. The Genbank accession number of the strain 16S rDNA is AY205564. Direct application of degrading bacteria products can reduce the amount of pesticide residues in the soil by more than 90%, solve the problem of excessive pesticide residues in agricultural production, and produce non-toxic and pollution-free green agricultural products.

Description

1. Technical field [0001] The invention discloses a triazine herbicide residue degrading bacterium and the bacterium agent produced therefrom, which belong to the field of biological high technology, degrade chemical pesticide residues by means of microorganisms, and are suitable for the production and processing of green and pollution-free agricultural products in modern agricultural production. 2. Technical background [0002] The use of chemical pesticides has greatly promoted the development of modern agriculture, saved a lot of losses caused by diseases, insect pests and weeds for agricultural production, and greatly improved the labor efficiency and mechanization degree of agricultural production. In the process of modernization of agricultural production played an immeasurable role. But at the same time, pesticides are some toxic and harmful chemicals. After they enter the ecological environment, they not only kill the organisms that are harmful to humans, but also ca...
