PROBIOTICS FOR BIOLOGICAL CONTROL AGAINST VIBRIO SP.

摘要

The present invention relates to probiotics for biological control against Vibrio sp., and in particular, to a newly isolated bacillus strain that degrades quorum-sensing signal molecules of the pathogenic bacteria Vibrio sp., and inhibits biofilm formation; a culture broth obtained by culturing the strain, a concentrate thereof, or a dry product thereof; a probiotic composition, a feed additive, an antimicrobial agent, or a water quality improving agent comprising the strain, the culture broth thereof, the concentrate thereof, or the dry product thereof; and a method for culturing fish or crustaceans, degrading quorum-sensing signal molecules of Vibrio harveyi and inhibiting biofilm formation, preventing bacterial infection in animals and improving water quality using the strain, the culture broth thereof, the concentrate thereof, or the dry product thereof.
