Abstract
In the marine eco system, seaweeds are directly exposed and are susceptible to ambient micro organisms such as bacteria, fungi and viruses. Seaweed species of padina (brown algae) from the coast of Tamilnadu, India were tested in vitro for their antibacterial activities against different types of bacteria using disc diffusion method. The algal extracts were tested for their antibacterial activity against six strains (Salmonella typhi, Vibrio alginolyticus, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Micrococcus luteus). Among four solvents tested, methanol exhibited more inhibitory effect followed by ethanol, aqueous and then acetone. Finally, we conclude that marine macro algae from the South coast of Tamilnadu, India are potential sources of bioactive compounds and should be investigated for natural antibiotics. The seaweed extract manifest preferable antibacterial activities, hence in the future, it would be good if it is further taken for treatment of human diseases.
