A kind of Lactobacillus pentosus, the fermentation product of the Lactobacillus and the application of the fermentation product

Abstract

The invention relates to a lactobacillus pentosus strain and a fermentation product of the same. The preservation number of the lactobacillus pentosus LPEM818 in the invention is CGMCC No. 4583 in the China General Microbiological Culture Collection Center. The fermentation product of the lactobacillus pentosus in the invention can inhibit common pathogenic escherichia coli, pseudomonas aeruginosa and staphylococcus aureus in food, and particularly has a strong inhibiting effect on listeria monocytogenes which can cause serious food poisoning. In addition, the metabolite of the strain also can inhibit the growth of aspergillus flavus and cotton and tomato blight pathogens. Consequently, the lactobacillus pentosus strain and the fermentation product thereof play an active role in the fields of food preservation and plant protection.

Description

technical field [0001] The invention belongs to the field of microbial resource utilization, and in particular relates to a lactobacillus pentosus, a fermentation product of the lactobacillus and the use of the fermentation product. Background technique [0002] Many foods in the market are now polluted, among which raw meat, aquatic products and quick-frozen foods in bulk are most polluted. Generally, food is preserved by low-temperature refrigeration or chemicals, but the effect is not satisfactory. Some preservatives even contain trace amounts of toxins, and long-term excessive intake will cause certain damage to human health. At the same time, some pathogenic bacteria such as Listeria monocytogenes widely exist in nature, and the bacteria can still grow and reproduce in the environment of 4 ℃, which is one of the main pathogenic bacteria that threaten human health in refrigerated food. [0003] Molds often grow and produce toxins, such as aflatoxin, found in moldy peanu...

[0004] Crop diseases cause serious losses to farmers and are difficult to control

Over the years, chemical control measures have not only failed to curb the rising trend of soil-borne diseases, but also inhibited the growth of beneficial microorganisms in the soil, leading to the development of drug resistance of pathogenic bacteria, and at the same time causing the residue of harmful substances in crops
