Protective agent for acetamiprid-degrading bacteria, preparation method and application thereof

Abstract

The invention discloses a protective agent for acetamiprid-degrading bacteria and its preparation method and application. The protective agent is composed of a stabilizer, a nutrient, a preservative and water. The stabilizer is composed of dextrin, and the nutrient is composed of are sodium citrate and calcium chloride, and the preservative ingredient is sodium benzoate. The protective agent of the present invention can effectively solve the problems of low number of viable bacteria, short storage period, and easy-to-contaminate microbial bacterial agents; it can effectively maintain the performance of the microbial agents, improve the survival rate of effective bacteria, prolong the storage life of the microbial agents, and make the microorganisms The bacterial agent can be preserved at normal temperature, and it is not easily contaminated with bacteria. The preservation method is low in cost and convenient to use, effectively reducing the cost of transportation and storage, and further ensuring the practical application of the pesticide-degrading microbial bacterial agent in pesticide degradation.

Description

Technical field [0001] The present invention belongs to the field of microbial degradation, relates to the protection of a pesticide degradation of microbial agents, specifically relates to a protective agent of acetamidine degrading bacteria and preparation methods and applications thereof. Background [0002] Due to the indiscriminate use of pesticides and the lack of reasonable scientific supervision and use management, pesticide residues lead to environmental degradation, seriously disrupt the balance of ecosystems, and cause structural damage and functional loss of ecosystems. Pesticide pollution is a kind of non-point source pollution, and there are certain defects in physical and chemical remediation methods. Because of its inherent characteristics, microorganisms occupy an important position in pesticide degradation. The use of microorganisms to repair the contamination of pesticide residues is recognized as a cheap, safe, effective and non-secondary pollution method. At...
