High-purity spore powder production process and verticle multi-layer spore-generating box thereof

Abstract

This invention discloses one kind of vertically and multi-layer producing spore's case , including the transparent case body (1), the case body (1) consists of the case door (7) that can be opened; One that is in case body (1) consist of at least two supplies dish (4) inside, case body (1) also consist of separately not well versed inning at least enter each and at least break up each by hole (5) not wet for hole (2) not wet for case body (l). This invention still uses above-mentioned vertical a multi-layer a kind of high purity spore powder production technology of producing spore's case publicly , including liquid phase ferment, making fermented host, making and inoculating the supplies , two stage types to ferment and produce spores , air dried treatment step. Producing spore's case vertically and multi-layer of this invention is of simple structure: High purity sub powder production technology that invent, simple technological process have, stop miscellaneous fungus pollute, do not pollute the environment, and high benefit produce high spore powder of purity.

Description

technical field [0001] The invention relates to a production process of high-purity spore powder based on a vertical multi-layer sporulation box. Background technique [0002] Research and development of microbial agents with effective infectants as active ingredients to control crop pests. Entomopathogenic fungi are important fungal biocontrol agents that can be used, because only fungi can infect and kill through body wall contact under natural conditions. Kill pests, can deal with different types of agricultural and forestry pests. At present, the hyphosporium insecticidal strains that are mainly researched and developed at home and abroad are mainly concentrated in a few species such as Beauveria bassiana, Metarhizium anisopliae and Paecilomyces. According to existing research reports, conidia (effective infectants) of insecticidal fungi can attach to the surface of the insect body, germinate under suitable conditions and produce germ tubes, penetrate the host body wall...

Problems solved by technology

For specific bacterial strains, the main technical key is to screen and use cheap and easy-to-obtain agricultural and sideline products as the nutritional substrate for two-phase fermentation to reduce production costs, thus forming the existing solid-phase fermentation spore production method at home and abroad. , the layered culture of indoor open simple bracket structure is generally adopted, the production line covers a large area, and the contamination of bacteria is prone to occur in large-scale production, and the humidity control in the production process is relatively difficult, resulting in a long production cycle and difficult to control

Therefore, the lack of technical equipment for solid-phase fermentation spore production is the main reason for the low production efficiency and high cost of biocontrol fungal spore powder, and is also a key factor restricting the industrialization of biocontrol fungal preparations

However, the existing solid-phase fermenter or related equipment is generally a fully enclosed metal structure designed for the production of yeast and koji species, which is opaque and cannot be used for the solid phase of biocontrol fungi for the purpose of producing aerial conidia powder. sporulation fermentation
