Antimicrobial properties of sea anemone Stichodactyla mertensii and Stichodactyla gigantea from Mandapam coast of India

Abstract

To investigate the antimicrobial activities of the methanol and aqueous extract of sea anemone Stichodactyla mertensii (S. mertensii) and Stichodactyla gigantea (S. gigantea). The sea anemone S. mertensii and S. gigantea were subjected to extraction by using methanol and distilled water. They were evaluated for antimicrobial activity against bacterial and fungal pathogens. In antibacterial activity, S. gigantea exhibited significantly inhibitory activity against Pseudomonas aeruginosa than the S. mertensii of butanolic extract. In antifungal activity, the S. mertensii extract showed good activity against Aspergillus niger (A. niger) compared with other strains. Whereas S. gigantea recorded maximum and minimum zone of inhibition against Botrytis cinerea, A. niger and Cladosporium cucumerinum respectively. The results support that the sea anemones S. mertensii and S. gigantea extracts for treatment of some bacterial and fungal diseases as an ethanomedicinal source.
