Abstract
The antibacterial activity of marine bacterium(Pseudomonas aeruginosa JYMB1-3) was assayed against Vibrio anguillarum with the aim of evaluating the possible use for biocontrolling fish disease as probiotic strain. Inhibition test on the solid medium showed that vibrios were especially sensitive to the JYMB1-3. Edwardsiella tarda, Streptococcus sp. and Staphylococcus epidermidis were also sensitive to that strain, however the antibacterial abilities were varied to the pathogens. The vibriostatic activity of antibacterial substance produced from cells of the strain for 24 hours was equivalent to of chloramphenicol.
