Abstract

The present invention belongs to a plant magnetism polyurethane foam plastic immobilized microorganism cell and the technology field of the biological degradation chemical pesticide, and relates to the magnetic immobilization to a strain cell which highly and effectively degrades the pyrethroid pesticide. The bacterial strain is acinetobacter (Acinetobacter sp.) JCX22D strain, which uses botanical wastes as polymerization material, and Fe 3 O 4 as a magnetic component, a cold curing technology is adopted to perform the immobilization of the strain cell, and the immobilized cell can be recycled through adding the magnetic field. The degradation efficiency of the immobilized cell to highly effective cypermethrin, lamba cyhalothrin and bifenthrin is more than 70 percent, the degradation efficiency to naled, methyl parathion, phoxim and chlorpyrifos is over 60 percent, and the degradation efficiency to avermectins is 85 percent. The magnetic immobilized cell can be used for the biolobical repair or biological purification of a water body polluted by the pesticide.

Description

technical field

[0001] The invention belongs to the technical field of chemical pesticide biodegradation by magnetically immobilized microbial cells, and relates to the magnetic immobilization of microbial cells with high-efficiency degradation capabilities for pyrethrins, organophosphorus, and avizyme, which are used for high-efficiency cypermethrin, trifluoro Cypermethrin, deltamethrin, bifenthrin, diazinon, methyl parathion, phoxim, chlorpyrifos, and avermectin pesticides for bioremediation and biopurification of water bodies. Background technique

[0002] Chemical insecticides are a class of toxic compounds used to control pests and play an important role in agricultural production. The output of pesticides and insecticides in my country accounts for 60% of the total output of pesticides in the country, and its main varieties are organophosphorus and pyrethroids.

[0003] Pyrethroids and organophosphorus pesticides are widely used on vegetables, tea, and fruit trees in ...
