Resumo: 	A bioassay-directed is utilized to detect substances with biological activity from Gracilaria tikvahiae, Ulva lactuca, Ulva fasciata and Sargassum fluitans. In a preliminary assessment, polar and non polar extracts of four species of marine protoctist form were screened for antibacterial and antifungal properties against seven microorganisms by the diffusion method, non polar extracts of Sargassumfluitans,and polar extracts of Gracilaria tikvahiae inhibited the growth of more than four microorganisms. Extracts were separated using chromatography column and fractions were tested againstStapylococcusaureus andCandida albicans. The eighty fraction of petroleum ether of S. fluitans exhibited high activity against C.albicans, MIC 0.16 µg/mL.
