Problems solved by technology

However, Nisin, the only nisin that is currently approved to be used as a food preservative, has relatively poor inhibitory effect on Gram-negative bacteria and molds, while other lactic acid bacteria bacteriocins still have problems such as few varieties, low yield, and not widely used, so looking for A new type of broad-spectrum lactic acid bacteriocin, and its detailed basic research and development and application research are of great significance for promoting the application of lactic acid bacteriocin in the food industry

Abstract

The invention provides lactobacillus paracasei and application thereof, belongs to the field of microorganisms, and provides a new strain with an antibacterial effect on the basis of the problems of few varieties, low yield and narrow application of existing lactic acid bacteria, and the preservation number of lactobacillus paracasei is CCTCC NO: M 2016667.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to Lactobacillus paracasei and its application. Background technique [0002] Since the new century, the extensive use of chemical preservatives in food has seriously threatened human health, causing allergic reactions in the human body and imbalance of flora in the body. The misuse of antibiotics and antibiotic resistance caused by drug residues in food of animal origin also have important impacts on food safety, public health and livestock production. Therefore, finding safe, efficient and green natural food preservatives and antibiotic substitutes has become a world trend in the development of the food industry and the protection of human health. Lactic acid bacteria are recognized as safe food-grade microorganisms. Due to their own safety and probiotic properties of bacteriocins, they have unique advantages in replacing chemical preservatives to achieve food preservation and repla...
