Organic phosphorus degrading enzyme preparation and preparation method thereof

Abstract

The invention relates to microbe technology, in particular to a degrading enzyme preparation for degrading residual organic phosphorus on vegetables and fruits and a preparation method thereof. The invention particularly relates to organic phosphorus degrading enzyme preparation obtained by fermenting Methylobacterium. The preparation process comprises the following steps: after fermenting the inoculated strain, centrifugally collecting thalli, and breaking thalli to obtain the organic phosphorus degrading enzyme preparation. The organic phosphorus pesticide degrading enzyme preparation can degrade residual organic phosphorus pesticides on vegetables and fruits.

Description

technical field The invention relates to microbial technology, in particular to an enzyme preparation for degrading residual organophosphorus on vegetables and fruits and a preparation method thereof. Background technique Organophosphorus pesticides are the main category of pesticides and play an important role in agricultural production. However, the problems of killing non-target organisms and polluting the environment cannot be ignored. Low doses of organophosphorus residues in vegetables, fruits and other foods can cause chronic toxicity to humans and induce polyneuropathy and stroke. In addition, some organophosphates are highly toxic to bees and fish. The residual toxicity of organophosphorus pesticides has attracted more and more attention. The degradation of organic phosphorus in the environment mainly includes three forms: photochemical degradation, chemical degradation, and microbial degradation. At present, the use of microorganisms and their metabolites to de...
