Probiotics are most commonly defined as viable microorganisms which, after sufficient oral intake, lead to beneficial effects for the host by modifying the intestinal microbiota. The objective of present study was to isolate and characterize different Bacillus strains having probiotic properties from gastrointestinal tract (GIT) of fish. The presence of probiotic bacteria in the digestive tracts of fish was subjected to several factors such as their ability to adhere to the surface of the intestinal epithelium and the production of substances that antagonise pathogenic microorganisms. Bacilli are spore forming bacteria which are heat resistant, that gives stability to microorganism in different environmental conditions this characteristics makes this organism most suitable to be used as probiotics strain. The selected 11 bacterial strains from GIT of fish were investigated for bile salt tolerance (1% to 8% concentrations), lipolytic activity, protease activity, haemolytic activity, catalase activity, hydrophobicity and autoaggregation. Among these 11 isolates, however, there was only 1 isolate, named as F10 which showed the haemolytic activity. Based on various activities results suggest that isolated strain F3 is considered to be suitable for probiotic applications.
