PROBIOTICS FOR BIOLOGICAL CONTROL AGAINST SAPROLEGNIA SP.

摘要

The present invention relates to probiotics for biological control against Saprolegnia sp., and in particular, to a newly isolated bacillus strain that inhibits the growth of a pathogenic fungus, Saprolegnia sp. and produces siderophores; 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, an antifungal 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, preventing saprolegniosis in animals and improving water quality using the strain, the culture broth thereof, the concentrate thereof, or the dry product thereof.
