Protective agent for carbendazim degrading bacteria, and preparation method and application thereof

Abstract

The invention discloses a protective agent for carbendazim degrading bacteria, and a preparation method and an application thereof. The protective agent is composed of a stabilizer, a nutritious agent, a preservative and water. The stabilizer comprises the component of carboxymethylcellulose, the nutritious agent comprises the components of sodium citrate and calcium chloride, and the preservativecomprises the component of sodium benzoate. The protective agent can effectively solve the problems of low number of living bacteria, short preservation period, easy bacteria infection and the like of microbial agents, can effectively maintain the performance of the microbial agent, improves the survival rate of effective bacteria, prolongs the preservation life of the microbial agent, makes themicrobial agent preserved at normal temperature, and is not easily infected with bacteria; the preservation method has low cost and convenient use, and effectively reduces the costs of transportationand preservation, and further guarantees the practical application of the pesticide degradation microbial agent in pesticide degradation.

Description

technical field [0001] The invention belongs to the field of microbial degradation, and relates to the protection of a pesticide-degrading microbial agent, in particular to a protective agent for carbendazim-degrading bacteria, a preparation method and application thereof. Background technique [0002] Due to the wanton use of pesticides and the lack of reasonable scientific supervision and use management, pesticide residues have led to environmental degradation, seriously disrupted the balance of the ecosystem, and caused structural damage and functional loss of the ecosystem. Pesticide pollution is a non-point source pollution, and physical and chemical remediation methods have certain defects. Due to their inherent characteristics, microorganisms play an important role in the degradation of pesticides. The method of applying microorganisms to remediate the pollution of pesticide residues is recognized as a cheap, safe, effective and non-secondary pollution method. At pr...
