Biomolecular constituents and antibacterial activity of some marine algae from Chilika Lake (Orissa, India)
RESUMO
Four marine algae were collected from saline waters of Chilika Lake and screened for their antibacterial activity and biomolecular constituents. In vitro antibacterial activity was tested against three gram positive and four gram negative bacteria. Maximum activity (23 mm) was observed in the aqueous extracts of Chaetomorpha sp. against Bacillus subtilis, and variable antibacterial activity (19 mm and 14 mm) was observed in Phormidium sp. against Bacillus subtilis and Escherichia coli, respectively. All other species did not show any antibacterial activity against the test pathogens. All of these marine algae showed great variation in biochemical constituents such as carbohydrates, lipids, proteins, total chlorophyll, proline, amino acid, ascorbic acid, and in phytochemicals like alkaloids, terpinoids, flavonoids, cardiac glycosides, anthroquinone glycosides, saponins, phlobatanin, gums and mucilages, and phenols. Their pharmacological activities and bioactive can be highly exploited.
