Abstract

The invention provides a preparation method of a spore preparation of bacillus coagulans. The preparation method of the spore preparation of bacillus coagulans comprises the following steps of: (a) slope thallus activation; (b) seeding tank cultivation of the bacillus coagulans; and (c) solid fermentation of the bacillus coagulans: placing the culture medium in the step (b) in a solid fermentation medium based on the weight ratio of 1%-10%, and fermenting for 48-72hours in a semi-closed manner. By using a semi-closed solid fermentation method, materials are in the semi-closed state in the process of fermentation and contact with a small amount of air, the bacillus coagulans can be propagated greatly by fully utilizing residual oxygen in the growing period, oxygen is greatly reduced in the later growing period, spore can grow rapidly, and more L-lactic acid can be metabolized, so that the problem that produced acid is insufficient in the fermentation process is solved, the growth of infectious microbe is inhibited through oxygen consumption, and the phenomenon of solid fermentation pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a preparation method of a spore preparation of Bacillus coagulans. Background technique [0002] In recent years, the frequent incidents of "lean meat powder", "turkey fish" and "red duck eggs" have sounded the national alarm on food safety, and have also aroused great attention from the party, the government and the general public. Traditional animal husbandry develops in pursuit of high feed remuneration, high growth rate, low cost to improve economic efficiency, and at the cost of sacrificing the environment and consuming resources. However, my country's animal husbandry will still account for a large proportion of the agricultural economy in a certain historical period. Therefore, the development of efficient and pollution-free breeding production technology is an inevitable way for the development of my country's animal husbandry. Pollution-free feed additive...
