Degradation bacteria for carbendazim pesticide residue and bacterial agent produced thereby

Abstract

The invention provides a carbendazim pesticide residue degrading bacteria and a prodegradant, which belongs to biological high-tech domain. The used bacterial strain DJL-6 is judged as Rhodococcus sp. The main biological feature is: G+, the thallus is of ball rod and atrichosis; the reaction between catalase and V-P is positive; the oxidase reaction is negative; the barley sugar, carubinose, citrate, acetamide and agedoite can be used as unique carbon source or nitrogen source to carry out its growth, but the lactin and bitter almond acid can not be used as unique carbon source to carry out its growth; and the bacterial colony is orange when cultivated on LB culture medium. The pesticide residual quantity of the crop can be reduced by more than 95 % by directly applying the degrading bacteria product, which solves the overproof pesticide residue problem, and can produce non-toxic and nuisanceless environmental farm product.

Description

1. Technical field [0001] The invention discloses a carbendazim pesticide residue degrading bacterium and the bacterial agent produced therefrom, which belong to the high-tech field of biology, use microorganisms to degrade chemical pesticide residues, 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, restored a large number of losses caused by diseases and insect pests for agricultural production, and greatly improved the labor efficiency and mechanization degree of agricultural production, playing a role in the modernization of agricultural production. immeasurable effect.

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 the health of the people and the export of agricultural products.
