Problems solved by technology

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 cause serious harm to the ecological system.
Extensive use of pesticides has caused pesticide residues in agricultural products to exceed the standard, seriously affecting people's health and export earnings of agricultural products

Embodiment Construction

[0013] The invention provides a degrading bacterial agent for eliminating buprofezin pesticide residues. The bacterial strain used is Gram staining-negative bacteria BF3, which is isolated from paddy field soil in Nanjing.

[0014] On April 3, 2009, it was preserved in the General Microorganism Center of China Committee for Culture Collection of Microorganisms. The strain preservation number is: CGMCC No.3001, and it was identified as Paracoccus sp. The main biological characteristics are Gram-negative, and the cells are short and rod-shaped. The colony is milky white to yellowish, round, raised, opaque, with neat edges and smooth surface. Facultative anaerobic, chemoheterotrophic.

Abstract

The invention provides a degrading residual microbial inoculum of buprofezin pesticide, belonging to the field of biological high technology. The used bacterial strain is gram staining negative bacteria BF3, and is identified as Paracoccus (Paracoccus sp.). The main biological characteristic is gram-negative and cell is clubbed. Bacterial colony is milky yellowish, round, swollen and opaque, with neat margin and smooth surface. The bacterial strain is facultative anaerobic and chemoheterotropic. The culture solution obtained by fermenting BF3 strain is the microbial inoculum. The application of degrading bacteria product can ensure that buprofezin pesticide residue quantity in soil is reduced by more than 90%, and can solve the overproof problem of buprofezin pesticide residue in agricultural production.

Description

1. Technical field [0001] The invention provides a buprofezin pesticide residue degrading bacterium and a bacterial agent produced therefrom, belonging to the high-tech field of biology, degrading chemical pesticide residues by means of microorganisms, and suitable for the production of green and pollution-free agricultural products in modern agricultural production. 2. Background technology [0002] The use of chemical pesticides has greatly promoted the development of modern agriculture, restored a large number of losses caused by plant diseases, insects, and weed damage for agricultural production, and greatly improved the labor efficiency and mechanization degree of agricultural production. played an invaluable role in the modernization process. But at the same time, pesticides are some toxic and harmful chemical substances. After they enter the ecological environment, they not only kill the organisms that are harmful to humans, but also cause serious harm to the ecologi...
