Plant lactobacillus solid inoculant, preparation method thereof and application of plant lactobacillus solid inoculant

Abstract

The invention relates to the field of microbial fermentation feed, in particular to a plant lactobacillus solid inoculant, a preparation method thereof and application of the plant lactobacillus solidinoculant. The method comprises the following steps: (1) inoculating a strain of plant lactobacillus into a first solid fermentation medium for first fermentation culture to obtain a first fermentation material; and (2) inoculating the first fermentation material into a second solid fermentation medium for second fermentation culture to obtain a second fermentation material; wherein the first solid fermentation medium contains a starchy raw material crushed product and starch dregs; and the second solid fermentation medium contains DDGS, DDS, starchy raw material bran and a calcium source. According to the technical scheme, two-time fermentation is performed on the plant lactobacillus in a specific fermentation medium, so that the metabolic capability of the strain is remarkably improved,and the lactic acid content and number of thalli in a finally obtained fermentation product are greatly increased, namely the fermentation effect is improved.

Description

technical field [0001] The invention relates to the field of microbial fermented feed, in particular to a solid bacterial agent of plant lactic acid bacteria and a preparation method and application thereof. Background technique [0002] Microbial fermented feed has natural fermented flavor and good food-attracting effect. Plant lactic acid bacteria, such as plant Lactobacillus, are the main probiotics in the intestinal tract of humans and animals. They have many health care functions, such as maintaining the balance of intestinal flora, regulating immunity, and promoting nutrient absorption; they have certain effects on pathogenic bacteria. Inhibitory effect, improving intestinal microenvironment; alleviating lactose intolerance. In addition, plant lactic acid bacteria are a type of microorganisms that normally exist in the digestive tract, and have strong tolerance and colonization ability in the intestinal mucosa. [0003] With the popularization of the application rang...

AI Technical Summary

Problems solved by technology

[0004] In the solid fermentation of plant lactic acid bacteria, the strains of plant lactic acid bacteria are usually inoculated into the solid medium for fermentation and culture, but the current solid fermentation method has the problem that the metabolism of the strains is not vigorous, resulting in low metabolite lactic acid content, bacteria Low body count, poor fermentation effect
