Problems solved by technology

Although the Abamectin residue contains a small amount of Abamectin (0.1-0.2%), it has been banned by the state because it can cause side effects such as diarrhea and hair choking in animals when it is used for animal deworming
Most of the manufacturers incinerate or directly discharge it into the environment, causing serious environmental pollution and waste of resources.

Abstract

The invention relates to the field of regeneration cycle utilization of antibiotic zymogen residues, provides a method using the abamectin residues as a raw material to prepare a product which is used for abamectin fermentation as a nutrient ingredient of a medium through processes of separation and concentration drying after microbes are fermented, and applies the product in the abamectin fermentation medium. The invention solves the problem of abamectin fermentation waste residues on environmental pollution, realizes regeneration cycle utilization of the waste residues, and achieves the aim of clean production.

Description

Technical field: [0001] The invention relates to the regeneration and recycling of antibiotic fermentation bacteria residue. In particular, it relates to the use of avermectin fermentation slag for avermectin fermentation as the nutrient component of the medium. Specifically, the abamectin residue is subjected to microbial fermentation treatment, and then added to the abamectin fermentation medium as a nutrient component of the abamectin fermentation. Background technique: [0002] Abamectin is an agricultural antibiotic produced by Streptomyces avermitilis through liquid submerged fermentation. It is mainly used to drive and kill parasites in and out of animals and agricultural pests. Because of its broad-spectrum, high-efficiency and safe anti-insect activity, it has become the most demanded agricultural antibiotic. In the process of avermectin fermentation production, Streptomyces avermitilis will multiply and produce a large amount of mycelium. After the abamectin in the myce...
