Feeding lactobacillus johnsonii high-density fermentation medium and application thereof

Abstract

The invention belongs to the technical field of lactobacillus culture, and relates to a feeding lactobacillus johnsonii high-density fermentation medium and application thereof. By using the high-density fermentation medium and the lactobacillus johnsonii fermented by a fermentation method for the fermentation medium, the bacterial density is remarkably improved relative to common fermentation, the number of viable bacteria is not less than 1,010cfu / ml and is improved by over 80 times compared with the viable bacteria cultured by a common MRS culture medium, and high-density fermentation of the lactobacillus johnsonii is realized; and according to the fermentation medium and the application thereof, the separation cost of biomass is reduced, the production period is shortened, the production cost is reduced, and the production efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of lactic acid bacteria cultivation, and relates to a high-density fermentation medium of Lactobacillus johnsonii for feeding and an application thereof. Background technique

[0002] Lactic acid bacteria are normal bacteria commonly found in the digestive tract of animals. The history of using this type of bacteria to develop probiotics is the earliest. This bacteria has been widely used in fermented food, animal feed and health food.

[0003] Lactobacillus johnsonii (Lactobacillus johnsonii) is a kind of lactic acid bacteria. Based on the current literature reports about Lactobacillus johnsonii, its beneficial function to animals is mainly reflected in the following two aspects. On the one hand, Lactobacillus johnsonii has a natural defense effect on animals. System and immune function have a regulatory effect; on the other hand, Lactobacillus johnsoni showed a specific preventive effect on animal dermatit...
