Actividades antimicrobianas de compuestos de algas del litoral de la isla de Gran Canaria

Abstract

Se ensayaron actividades antimicrobianas de 40 extractos tolueno-metanólicos de macroalgas (Chlorophyta, Rhodophyta y Phaeophyta) contra cuatro microorganismos. Se encontró actividad antibacteriana en 9 de los extractos y ninguno era activo contra la levadura. También se ensayaron dos sesquiterpenos (elatol y obtusol) aislados a partir del alga roja Laurencia obtusa

Lipid extracts of 40 macroscopic seaweeds (Chlorophyta, Rhodophyta and ·Phaeo­phyta) were assayed for their antimicrobial activities against four microorganisms. Sorne degree of antibacterial activity was found to be present in 9 of these extracts, while none was active against yeast. Two halogenated metabolites isolated from the red algae Laurencia obtusa were al so assayed.
