Antagonistic Activities of Bacillus spp. Strains Isolated from the Fishes
Keywords:
Bacillus, Lactobacillus, Fishes, Isolation, Antimicrobial.Abstract
In this research, antagonistic activities of 30 Bacillus species isolated from various fish samples were studied. Isolated Bacillus
species were analyzed using the agar diffusion method in terms of their general inhibition effects against some food pathogen/
contaminant bacteria and lactic acid bacteria isolated from the fish intestinal tracts. Some of the strains exhibited antimicrobial
activity against Bacillus subtilis, Pseudomonas fluorescens, Lactobacillus coryneformis, Lactobacillus plantarum and Lactobacillus
xylosus. Furthermore, the inhibitory effects of the lactic acid bacteria on the Bacillus isolates were analyzed by using the same
method.
It was determined that the lactic acid bacteria inhibited Bacillus spp. strains at different levels of inhibition zones.
