Seaweeds are regarded as a prospective source of bioactive compound. In the present study, the algae Dictyota dichotoma have been extracted using hexane, chloroform and ethanol and were tested for antibacterial activity against the standard culture of gram positive and gram negative bacterial strains. The results of the present study showed a proficient activity of the algae against all the bacterial strains under hexane extract. Thus the test report implied Dictyota dichotoma to possess good antimicrobial activity.
