Abstract

The invention discloses an application of bdellovibrios in removing pathogenic vibrio in marine food products and the culture water. The bdellovibrio concentrated solution is added into the marine food products and / or the culture water so as to lead the concentration of the bdellovibrio to reach at least 10<2>pfu / ml. When the invention is applied before eating the marine food products, in the transportation process and in the culture water, the concentration range of bdellovibrio is respectively 10<4>-10<12> pfu / ml, 10<3>-10<11> pfu / ml, and 10<2>-10<6 > pfu / ml. More than 90% pathogenic vibrio carried by marine food products before eating and / or in the transportation process is cleared by adopting a biological method, and the pathogenic vibrio in the culture water can also be controlled within10cfu / ml. The invention is suitable for the pretreatment process before being eaten or processed, the transportation process and the culture process of marine food products, especially facilitating the reduction or elimination of chemical medicine residues such as antibiotics, thus fundamentally avoiding the occurrence of food poisoning of the marine food products.

Description

technical field

[0001] The invention belongs to the field of biotechnology, relates to bacteria and its application, specifically refers to the application of Bdellovibrio to eliminate pathogenic Vibrio in seafood and its culture water, and is especially suitable for eliminating seafood before eating or processing, during transportation and Common food poisoning Vibrio in its culture water. Background technique

[0002] Pathogenic Vibrio is the most common pathogenic bacteria that causes seafood food poisoning in humans. It often exists in the surface and body of seafood shellfish and fish, and accounts for a considerable proportion in food poisoning. It mainly causes acute gastroenteritis, especially Vibrio parahaemolyticus (Vibrio parahaemolyticus), etc., have strong pathogenicity, rapid onset, fast transmission, many sources of infection, and long duration of epidemic among the population.

[0003] Studies have shown that there are about 9 common Vibrio species that can ...
