Bacteriocin-producing paenibacillus and application thereof

Abstract

The invention provides a bacteriocin-producing paenibacillus ehimensis strain NPUST-1 which can promote the growth and immunoreaction of aquaculture organisms. At the same time, the strain can also improve the survival rate of aquaculture organisms after being infected with pathogenic bacteria. In addition, the bacteriocin Peocin produced by the paenibacillus ehimensis strain NPUST-1 is a DNA protective protein in the starvation/stagnation period, and has antibacterial activity against a variety of pathogens including culture pathogens, foodborne pathogens and clinical pathogens. The bacteriocin Peocin is found out to be the DNA protein in starvation/stagnation period and with antibacterial activity for the first time.

Description

technical field [0001] During the breeding process of aquaculture organisms, because most of them are intensive farming, the infection of pathogenic bacteria is easy to spread rapidly, causing a large number of aquaculture organisms to die, causing huge economic losses. Therefore, the disease problem is a serious problem hindering the development of the aquaculture industry. In the face of disease problems, antibiotics or chemical agents are mainly used for prevention or treatment on the market at present. However, chemical agents are also toxic to non-standard organisms, and continuous use is likely to harm the human body or cause environmental pollution. At the same time, the abuse of antibiotics will lead to the emergence of drug resistance of pathogenic bacteria, resulting in the destruction of the ecological environment. Therefore, in recent years, based on the viewpoint of food safety and sustainable development of the environment, the demand for biological control meth...
