Abstract

The invention discloses a preparation method and application of immobilized Brevundimonas naejangsanensis bacteria highly efficient in degrading Dimetachlone. Brevundimonas naejangsanensis CCTCC M 2017739 is used as a strain, and 4% sodium alginate and bamboo charcoal are used as immobilization materials, in order to efficiently immobilize the Brevundimonas naejangsanensis strain to prepare immobilized bacteria. The immobilized bacteria can be applied to efficient and thorough degradation of Dimetachlone, vinclozolin and iprodione in soil and water, and has the advantages of good persistence,environmental friendliness, remarkable effect, low cost and easy promotion.

Description

Technical field

[0001] The invention relates to the field of biotech degradation of pesticide residues, in particular to a preparation method and application of immobilized bacteria of the genus Sclerotium that efficiently degrade Sclerotium. Background technique

[0002] Pesticides play an important role in the comprehensive management of agricultural diseases and insect pests, but pesticide residues and their metabolites have become serious pollutants, posing a threat to human health and ecosystems. Dimetachlone, also known as Wenkuli, molecular formula C 10 H 7 Cl 2 NO 2 , Its relative molecular mass is 244.07, and its chemical name is: N-(3,5-dichlorophenyl) succinimide. It is widely used in the prevention and treatment of fungal diseases such as sclerotium, sheath blight, brown spot and other crops on rapeseed, Chinese cabbage, laver, lettuce, leeks, cucumber, tomato, pepper, potato, tobacco and other crops in China. Although Sclerotium has a promising prospect of bacterici...
