Fluoroglycofen degrading bacteria and bacterial agent prepared from same

Abstract

The invention provides a degrading bacterial agent for removing fluoroglycofen residue, and belongs to the field of biological high technology. The strain is gram-negative bacteria MBLHY-1 which are found to be sphingomonas sp. through identification; and biologically, the strain is gram-negative, rodlike, sporeless and 0.8-1.3*0.5-0.6mu m long with polarflagella, is catalase-positive, oxidase-negative, voges-proskauer reaction-positive and methyl red reaction-negative, cannot hydrolyze starch or liquefy gelatin, does not generate indole, and can hydrolyze Tween-80. The pesticide residue in soil is reduced by over 90 percent and the problem that the pesticide residue exceeds the standard in agricultural production is solved by directly applying a degrading bacteria product; and nontoxic and pollution-free agricultural products can be produced.

Description

1. Technical field [0001] The invention discloses a fluorinated acetoxyfen residue-degrading bacterium and the bacterium agent produced therefrom, belonging to the field of biological high technology, degrading chemical pesticides by means of microorganisms, and applicable to the production and processing of green and pollution-free agricultural products in modern agricultural production. 2. Background technology [0002] Fluorine-containing pesticides are emerging pesticides that have been used in recent decades. The fluorine atom has the characteristics of small radius and high electronegativity. The introduction of fluorine atoms and fluorine-containing groups (such as: -CF3) into biologically active organic compounds can greatly improve the stability and physiological activity of organic fluorides. So it has become a hot spot of research and development today. However, the extensive use of fluorine-containing pesticides leads to the residues of such pesticides in the so...

AI Technical Summary

Problems solved by technology

However, the extensive use of fluorine-containing pesticides leads to the residue of such pesticides in the soil and water environment, which may pose a potential threat to the ecological environment and human health. Therefore, environmental behaviors such as the migration, transformation and decomposition of fluorine-containing pesticides in the environment are increasingly being focus on
