Abstract/Summary
Twelve species of algae collected from St. Paul's Bay, Palawan, were tested for the presence of antimicrobial activity using the paper disc agar diffusion method. The seaweed species studied belong to class Phaeophyceae, Chlorophyceae and Rhodophyceae. Ethanol, ethyl acetate, hexane and ether extracts of the algae were tested against Staphylococcus aureus, Escherichia coli, Salmonella typhosa, Pseudomonas aeruginosa, and Candida albicans. Results showed that the ethanol and ethyl acetate extracts of Laurencia papillosa exhibited antimicrobial activity against Staphylococcus aureus. The remaining algal extracts did not inhibit the growth of any of the test microorganisms. Further phytochemical study to identify and isolate the active components of L. papillosa and toxicity testing of the extract are recommended.
