preparation example Construction

[0030] The present invention also provides a method for preparing a compound fermented product inhibiting Aspergillus flavus described in the above technical scheme, comprising the following steps:

[0031] Inoculating two or three strains of Lactobacillus plantarum, Pediococcus lactis and Bacillus coagulans into the fermentation medium, fermenting at 32-37°C for 20-30 hours, separating solid and liquid to obtain a composite fermentation supernatant; The composite fermentation supernatant is concentrated 8 to 15 times to obtain the composite fermentation product inhibiting Aspergillus flavus.

[0032] In the present invention, the bacterial suspensions of Lactobacillus plantarum, Pediococcus lactis and Bacillus coagulans are taken respectively, according to OD 600 The ratio of values ​​is 0~2:0~2:0~2 in order to obtain strains; among them, the bacterial suspension OD of Lactobacillus plantarum, Pediococcus lactis and Bacillus coagulans 600 Among the ratios of values, at most ...

Abstract

The invention provides a composite leavening inhibiting aspergillus flavus and a preparation method and application of the leavening and relates to the technical field of microorganisms. The compositeleavening inhibiting the aspergillus flavus is a composite fermentation supernate of two or three of lactobacillus plantarum, pediococcus acidilactici and bacillus coagulans. It is shown through an aspergillus flavus inhibition test recorded in the embodiment that concentrates of fermentation supernate of the lactobacillus plantarum, pediococcus acidilactici and bacillus coagulans have an inhibition effect on growth of the aspergillus flavus, and a concentrate of the composite fermentation supernate of the lactobacillus plantarum, pediococcus acidilactici and bacillus coagulans also has an inhibition effect on growth of the aspergillus flavus. The composite leavening is a composite fermentation product of two or three of the lactobacillus plantarum, pediococcus acidilactici and bacillus coagulans and is safe to the human and environment. Therefore, the invention provides a safe and effective inhibition agent for the aspergillus flavus.

Description

technical field [0001] The invention relates to the technical field of microbes, in particular to a compound fermented product inhibiting Aspergillus flavus and its preparation method and application. Background technique [0002] Aspergillus flavus is a kind of spoilage microorganism with extremely tenacious vitality. Its growth in animal feed will cause harm to humans and animals. At the same time, Aspergillus flavus is one of the main pollution sources that cause feed spoilage and mildew during feed storage and storage. [0003] A lot of research has been done at home and abroad on how to inhibit the growth of Aspergillus flavus, such as physical methods such as heat treatment and infrared treatment, and chemical methods such as adding additives such as lactic acid and benzoic acid, etc. However, with practical application, these traditional methods have not yet been proved to be economical, effective and feasible . Research and development of green feed additive product...
