In Vitro Probiotic Characterization and Whole-Genome-Based Safety Screening of Bacillus spp. Isolated from the Gastrointestinal Tract of Betta splendens Regan
Spore-forming Bacillus probiotics are widely used in aquaculture, but host-associated strains from Siamese fighting fish (Betta splendens Regan) remain uncharacterized. Ten Bacillus isolates were recovered from the gastrointestinal tract of farmed B. splendens by heat selection and were identified by biochemical testin...
