Streptomyces microflavus solid fermentation medium and preparation method thereof, streptomyces microflavus fermentation method and fermentation product, bio-control products of fermentation product as well as application of fermentation product and bio-control products

Abstract

The invention provides a streptomyces microflavus solid fermentation medium and a preparation method thereof, a streptomyces microflavus fermentation method and fermentation product, bio-control products of the fermentation product as well as application of the fermentation product and bio-control products, and relates to the technical field of microbial fermentation. The streptomyces microflavussolid fermentation medium is prepared from the following components in parts by weight: 40-50 parts of bran, 15-25 parts of rice hull, 25-35 pats of rice bran, 3-7 parts of calcium carbonate, and water. The streptomyces microflavus fermentation method comprises the steps of optionally enabling a strain of streptomyces microflavus to be subjected to seed activation and liquid seed culture, and performing fermentation culture by using the streptomyces microflavus solid fermentation medium to obtain the fermentation product. The streptomyces microflavus fermentation method overcomes the defect that the existing streptomyces microflavus is less in viable count and sporulation quantity. When being used for solid fermentation culture, the streptomyces microflavus solid fermentation medium is short in fermentation cycle and more in viable count, thus being suitable for industrial production; the obtained fermentation product has a significant effect in the aspect of controlling bacterial wiltof crops, thus increasing the quality and yield of the crops.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a Streptomyces luteus solid fermentation medium, a preparation method and a fermentation method thereof, a fermentation product, a biocontrol product and an application. Background technique [0002] Plant diseases are one of the natural biological disasters that seriously threaten agricultural production. The use of chemical agents not only kills beneficial farmland microorganisms and destroys farmland ecosystems, but also remains in soil, water bodies, agricultural by-products and livestock products, posing a threat to human health. Moreover, many pathogenic bacteria are resistant to drugs, leading to an increase in the frequency and dosage of chemical agents year by year, and the control effect is poor. Biological control has no effect on beneficial microorganisms in the environment, no residue and no pollution, no killing of natural enemies, no drug resistance,...

AI Technical Summary

Problems solved by technology

[0005] Streptomyces microflavus (Streptomyces microflavus) is a species of Streptomyces (Streptomyces), its own metabolites can effectively promote plant growth, can produce active ingredients such as zeatin, kinetin, etc. Streptomyces flavus are too few to play the above role

However, in the prior art, the number of viable bacteria and the amount of sporulation after fermentation of Streptomyces flavinus are few, and the activity and quality stability of the bacterial agent are poor.
