Nitrogen source suitable for efficient proliferation of lactobacillus plantarum and application thereof

The invention discloses a nitrogen source suitable for efficient proliferation of lactobacillus plantarum and application thereof, and belongs to the technical field of microorganisms. The invention provides the nitrogen source suitable for growth and reproduction of the lactobacillus plantarum. A strain is added into a culture system taking the nitrogen source as a unique nitrogen source, so thatthe growth rate of the lactobacillus plantarum can be remarkably improved, and the viable count of the lactobacillus plantarum in fermentation liquor is high; the viable count of the lactobacillus plantarum in a specific nitrogen source per unit mass is not lower than 3.0*108CFU/g, and is improved by 70 percent or above compared with that of a control group; and the nitrogen source is suitable for large-scale industrial culture of the lactobacillus plantarum, so that the industrial benefit is improved. 本发明公开了一种适用于植物乳杆菌高效增殖的氮源及其应用，属于微生物技术领域。本发明提供了一种适用于植物乳杆菌生长繁殖的氮源，将菌株添加至以此氮源为唯一氮源的培养体系中，可使得植物乳杆菌的生长速率显著提高，发酵液中植物乳杆菌活菌数高；
