Antibiotic Properties of Marine Algae. II. Screening of Chilean Marine Algae for Antimicrobial Activity

Abstract
Petroleum ether extracts of 33 spp. of macroscopic seaweeds (Chlorophyta, Rhodophyta and Phaeophyta) were assayed for their antibacterial activity against Sarcina lutea [Micrococcus luteus] ATCC 1001, Staphylococcus aureus ATCC 6538 P and Bacillus subtilis ATCC 6633. Some degree of antibacterial activity was present in 17 of these 33 extracts.
