Embodiment 1

[0012] A. Streptomyces avermanii, the abamectin-producing strain, was first naturally isolated in the strain room, coated with double-disc culture medium, and cultured at a constant temperature (28.0±0.5°C) for 7 days, and the single bacteria fell into the slope of the eggplant bottle at a constant temperature ( 28.0±0.5°C) for 10 days, and the slant strains with high titer were screened out by shaking flasks, and the spores or hyphae of the strains produced were inserted into the seed tank under sterile conditions. In the seed medium, After culturing for 45 hours under suitable culture conditions, when the concentration of the seed liquid reaches above 28%, the hyphae form a net and tend to form balls, and then transfer to a fermenter. In the fermentation medium, after culturing for 300 hours under suitable culture conditions, when the total sugar consumption is below 2%, and the reducing sugar consumption is below 0.8%, the hyphae have obvious autolysis phenomenon under the m...

Abstract

The invention relates to an environmentally-friendly abamectin ointment production process. The environmentally-friendly abamectin ointment production process comprises the following steps of: A, fermenting abamectin; B, filtering and drying a fermentation solution; C, extracting with secbutyl acetate, washing and filtering; D, concentrating the extract into paste to obtain an environmentally-friendly abamectin ointment product; and E, continuously extracting, dissolving and repeatedly crystallizing the concentrate to obtain a fine abamectin powder product. The environmentally-friendly nontoxic secbutyl acetate solvent is used for substituting a toxic toluene solvent to produce the abamectin ointment product, so that secondary pollution of the toxic solvent to a farmland is reduced, the harm of the toxic solvent to a user is reduced, and precious petroleum resources are saved.

Description

technical field [0001] The invention relates to an environment-friendly abamectin ointment production process. technical background [0002] Abamectin is a low-toxicity, high-efficiency, high-selection, green, environmental-friendly, bio-sourced insecticide. It completely solves the problems of high toxicity, resistance and impact on the environment of traditional pesticides. It is my country's " Seventh Five-Year Plan, Eighth Five-Year Plan, Ninth Five-Year Plan, Tenth Five-Year Plan and Eleventh Five-Year Plan. With the popularization and promotion of Abamectin and its downstream products in recent years, it has not only led to the vigorous development of my country's agriculture and animal husbandry, but also promoted the transformation of agricultural and animal husbandry production to a green and harmless direction. [0003] Abamectin, one of the most effective insecticides in the world, has an annual consumption of about 2,500 tons in China, making it a leading product...
