The biochemical analysis was done to study the
virulence potential and confirmation of vibrio strains. All the 2
isolates of Vibrio sp are gramnegative short curved rods and they all
show darting type of motility. The breakdown of starch was rather
more complicated than that of sugars, because of their extensive
hydrolysis. In this study, the isolates showed positive for starch
hydrolysis. Casein is a milk protein composed of amino acid. The
hydrolysis of casein was mediated by the enzyme protease, which
clearly demonstrated by a clear envelop surroundings the bacterial
growth
