Lactobacillus plantarum UCN-11 strain, and composition and application thereof

Abstract

The invention belongs to the fields of microbes, food preservation and animal feed, and particularly relates to a Lactobacillus plantarum UCN-11 strain, and a composition and application thereof. The new strain has the functions of food preservation and animal health care, and can ensure the shelf life of food and high-efficiency healthy cultivation of animals. The collection number of the new strain at China General Microbiological Culture Collection Center is CGMCC No.9480. The strain, fermentation nutrient material, fermentation liquid or thallus obtained by centrifugating the fermentation nutrient material, and the dried substance of the fermentation liquid or thallus are effective constituents for preparing food. The preparation process does not need to add any chemical preservative or perform irradiation treatment, maintains the original freshness of the meat food and obviously enhances the quality. The shelf life can exceed 6 months. The strain can remove the peculiar smell in the meat product and improve the flavor. The food can be eaten for a long time, and can increase the quantity of probiotics in the human body. No antibiotics are added in the whole animal feeding process, thereby obviously promoting healthy growth of animals, lowering the cost and enhancing the economic benefit.

Description

technical field [0001] The invention belongs to the fields of microorganisms, food preservation and animal feed, and in particular relates to a Lactobacillus plantarum UCN-11 strain and a composition and application thereof. Background technique [0002] Lactic acid bacteria is a general term for a type of bacteria that can produce a large amount of lactic acid by fermentation. It is widely distributed in nature and is a group of important probiotic microorganisms that live in the body and benefit the health of the host. Its role in maintaining human and animal health has been generally recognized. [0003] During the lactic acid fermentation process of some lactic acid bacteria, only lactic acid in the fermentation product is called homolactic fermentation. The representative bacteria are Diplococcus, Streptococcus and Lactobacillus, etc. The most commonly used strain in industrial fermentation is Lactobacillus. some species in the genus. [0004] However, there are also s...

Problems solved by technology

[0007] The lactic acid bacteria of heteromorphic lactic acid fermentation also often bring troubles to the aquaculture industry. They exist in large quantities in animal breeding environments, general processed feeds, especially green feeds or fermented feeds. Further generate a large amount of harmful gas, which will cause flatulence, oppress the heart and lungs, cause blood circulation disorders, and suffocate animals and pigs, which has become a major problem to be solved in the breeding industry.
