Abstract

The invention discloses a lactobacillus plantarum liquid fermentation culture medium. The lactobacillus plantarum liquid fermentation culture medium comprises the following components: 20-30 g/L of glucose, 10-15 g/L of soybean meal, 5-10 g/L of a saccharomyces cerevisiae extract, 2-5 g/L of dipotassium phosphate, 5-10 g/L of ammonium chloride, 3-6 g/L of sodium chloride, 5-10 g/L of calcium carbonate, 0.2-0.5 g/L of magnesium sulfate and 0.02-0.05 g/L of manganese sulfate. The invention also discloses a culture method for fermentation of lactobacillus plantarum liquid and application of thefermentation medium in the culture method for fermentation of the lactobacillus plantarum liquid. According to the invention, the glucose monohydrate, the soybean meal, the saccharomyces cerevisiae extract and the ammonium chloride thereof are adopted as raw materials, the composition of the medium is optimized, the technical method of fermentation operation is simplified, the viable count of lactobacillus plantarum is obviously improved, meanwhile, the production cost is reduced, and the production process is simplified.

Description

technical field [0001] The invention belongs to the technical field of culture and fermentation of lactic acid bacteria, and relates to a liquid fermentation medium of Lactobacillus plantarum, a cultivation method thereof, and an application of the fermentation medium. Background technique [0002] Lactobacillus plantarum, a type of lactic acid bacteria, is an anaerobic or facultative anaerobic Gram-positive bacterium. Lactobacillus plantarum acts as a probiotic in the intestinal tract of animals. It can produce natural antibacterial substances such as organic acids and bacteriocins, inhibit the growth of pathogenic bacteria such as E. coli and Salmonella, and improve intestinal health. At the same time, Lactobacillus plantarum can effectively degrade harmful substances such as organic matter in water, ammonia nitrogen and nitrite, and is now widely used in animal feed additives and water environment restoration agents. [0003] The culture of lactic acid bacteria in the la...
