Antagonistic effect of epiphytic bacteria from marine algae, southeastern India.

Aim of this study was to evaluate the antagonistic potential of epibiotic bacteria from seaweeds, Ulva lactuca, Dictyota dichotoma and Padina tetrastromatica against some potent human pathogens. The epibiotic bacteria of Ulva lactuca shows higher level of inhibition properties than the other species. The strain UL1 shows broad spectrum inhibitory activity against 7 pathogens. The inhibitory level of epibiotic bacteria ranged from low to moderate activity. The present investigation suggests that the epibiotic bacteria are good source for the isolation of antibacterial compounds of biomedical importance. The compounds can further be purified and can used to save mankind from dreadful diseases.
