- Abstract
Seaweeds or marine macro algae are potential renewable resources in the marine environment. Seaweeds are considered to produce a great variety of secondary metabolites characterized by a broad spectrum of biological activities. Extracts of marine algae were reported to exhibit antibacterial activity. In this study, the seaweeds Sargassum fluitans and Stoechspermum marginatum were selected and screened for the presence of phytochemical constituents such as flavonoids, tannins, phenolics, sterols, alkaloids, terpenoids, protein, carbohydrate and glycosides. Among the 10 phytochemicals studied, all the Phytochemicals are present in the ethanol extract of Sargassum fluitans.Antibacterial activity of seaweeds such as Sargassaum fluitans and Stoechspermum marginanum were tested against bacteria Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Pseudomonas aeruginosa. The result revealed that Bacilli subtilis, the gram positive bacilli was resistance to all the extracted solvents of Sargassaum fluitans. But Stoechspermum marginanum showed a small susceptibility pattern of the ethanolic extract and not to the chloroform extract. Antifungal activity of the Sargassaum fluitans and Stoechspermum marginanum were tested against two species such as Candida parapsilosis and Aspergillus niger. Among the pathogens Candida parapsilosis was effective in all solvents of Sargassaum fluitans and Stoechspermum marginanum. No activity was found in the aqueous and chloroform extract of Sargassaum fluitans and Stoechspermum marginanum against Candida parapsilosis and Aspergillus niger.
