Journal of Marine Science and Technology

Marine macroalgae generally keep their surface free from fouling organisms by their antifouling defence. Antifouling activity has been attributed to the production of secondary metabolites. In the present study, antifouling performance of the macroalga Halimeda sp., collected from the Red Sea coastal waters, was assessed using extracts prepared through various methods, including surface extraction, wet sample extraction and dried sample extraction. The solvents methanol and hexane were used to assess the effect of solvents on bioactivity. Results indicated that extracts of the macroalga inhibited growth and settlement of a biofilm-forming bacterial strain. Though the extracts prepared using different methods and …


Biopotentials Of Ulva Fasciata And Hypnea Musciformis Collected From The Peninsular Coast Of India, Joseph Selvin, Aaron Premnath Lipton Feb 2004

Biopotentials Of Ulva Fasciata And Hypnea Musciformis Collected From The Peninsular Coast Of India, Joseph Selvin, Aaron Premnath Lipton

Journal of Marine Science and Technology

The secondary metabolites of seaweeds Ulva fasciata and Hypnea musciformis, collected form southeast and southwest coast of India, were tested for biotoxicity potential. Both species showed potent activity in antibacterial, brine shrimp cytotoxicity, larvicidal, antifouling and ichthyotoxicity assays. The green alga U. fasciata exhibited broad-spectrum antibacterial activity whereas the red alga H. musciformis showed narrow spectrum antibacterial activity. The brine shrimp cytotoxicity profile indicated that the seaweeds were moderately toxic. The overall activity profile indicated that U. fasciata contained more biological potency than H. musciformis.
