Abstract

Marine organisms produce a huge number of secondary metabolites, perhaps to a larger expense than observed in terrestrial ecosystems. Ascidians are marine sedentary organisms. Ethanolic extract of the simple ascidian, Phallusia nigra Sav. has been tested against ten bacterial and three fungal pathogens by using disc diffusion method. The antimicrobial effects of animal extract against the different strains are presented and it is found that the inhibitory effect was proportional to concentration gradient.

Keywords: Phallusia nigra, antibacterial, antifungal, disc diffusion, MIC.
