Biopotentials of Ulva Fasciata and Hypnea Musciformis Collected from the Peninsular Coast of India

Abstract

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.
