Potential Antibacterial Activities of Seagrasses from Vellar Estuary; Southeast Coast of India

The present investigation carried out the antibacterial activity of seagrasses such as Halophila ovalis and Halodule pinifolia. Different organic solvents like diethyl ether, acetone and methanol were for the present study and tested the activity against Acenetobacter sp., Salmonella typhii, Micrococcus sp., Shigella sonii, Vibrio cholerae, Staphylococccus sp., Proteus vulgaris, P. mirabilis, P. aeruginosa and Salmonella paratyphi-B. The maximum antibacterial activity was recorded from the ethanol extracts of H. pinifolia against Acinetobacter sp., (20 mm), Salmonella typhii (20 mm), Proteus mirabilis (20 mm) and Pseudomonas aeruginosa (20 mm) showed the no activity against pathogens like Vibrio cholerae and Salmonella paratyphi-B.
