Eight morphologically different bacterial strains were isolated from rhizosphere saline soil of coastal Odisha, India. Among them only 3 rhizobacterial strains namead as P1, B1 and B2 belong to genus Bacillus had shown antibacterial activity against 5 human pathogenic bacteria in agar well diffusion method. Zone of inhibition showed by P1 against Salmonella typhi and Shigella flexneri was 8.567±0.03 and 8.133±0.03 respectively where as B2 showed 20.067±0.38 against Streptococcus pyogenes. B1 showed antibacterial activity against all the tested pathogens Streptococcus pyogenes (Gr +ve), Salmonella typhi (Gr -ve), Shigella flexneri (Gr -ve), Streptococcus mutans (Gr +ve), and Vibrio cholera (Gr -ve) i.e., 14.1±0.36, 11.767±0.21, 21.1±0.36, 21.333±0.29 and 12.1±0.2 respectively. After treatment with trypsin, organic solvents (acetone, methanol, ethanol and chloroform), heat and autoclave the metabolic activity of active components produced by test organisms were not changed.
