Problems solved by technology

[0004] The purpose of the present invention is to provide a method for extracting and concentrating wuyiencin bactericide, so as to solve the problems of easy degradation of wuyiencin fermentation liquid when the temperature rises in the post-treatment process, viscous and sticky walls of the fermentation liquid, long filtration time and low yield, etc. The disadvantage is that the extraction and concentration of the fermentation broth can not only keep the activity of Wuyiencin from being damaged, but also increase the yield and reduce energy consumption

Embodiment Construction

[0009] As shown in the accompanying drawing: the fermented feed liquid containing Wuyiencin discharged from the fermenter is filtered by nylon cloth through a conventional plate and frame filter press 1, and the filtrate rich in antibiotics enters the liquid tank 2 to be treated, and the filter residue is fermented bacteria Mycelium and some nutrient source residues, etc. The feed liquid in the liquid tank 2 to be treated is pressurized by the feed liquid pump and enters the fine filter 3 and the ultrafilter 4 for filtration. The fine filter 3 is a maintenance facility to avoid damage to the ultrafiltration membrane by a very small number of impurities entrained in the feed liquid and equipment pipelines. It also removes some particles to reduce the blockage of the ultrafiltration membrane and prolong the service life of the ultrafiltration membrane. The feed liquid in the ultrafilter 4 can also be returned to the feed liquid tank 2 to be treated through a pipeline and then ci...

Abstract

The invention discloses a method for extracting and concentrating Wuyiencin bactericide. After being filtered by a plate and frame filter press, the fermented liquid enters a feed liquid tank to be treated, is pressurized by a feed liquid pump, enters a fine filter and an ultrafilter in turn, and passes through The filtrate filtered out of the ultrafilter enters the circulating storage tank, and then enters the nanofilter after being pressurized by a multi-stage pump. The mycocin content reaches the predetermined concentration. The invention concentrates at normal temperature, has a simple process, does not harm the activity of the active ingredient of Wuyiencin, has high interception rate of the active ingredient and low energy consumption.

Description

Technical field [0001] The invention relates to the technical field of preparation of agricultural antibiotic fungicides, in particular to a method for extracting and concentrating Wuyienin fungicides. Background technique [0002] Wuyiencin is an agricultural antibiotic bactericide produced by Streptomyces ahygroscopicus var.wuyiensis (see "Acta Microbiology" 1984, vol. 24, pages 401-402: Identification of the agricultural antibiotic BO-10 producing bacteria) , is a high-efficiency, broad-spectrum, low-toxic, non-polluting biological pesticide. Its active ingredient is the metabolite produced by the Wuyiencin-producing bacteria in the biological submerged culture and fermentation. This metabolite is easily soluble in water, and with the increase of the content of the metabolite in water, the stability and efficacy of the biopesticide will be better. Therefore, the production of high-content Wuyiencin aqueous formulations is of great significance to the agricultural product...
