Antibacterial potential of Antarctic lichens against human pathogenic Gram‐positive bacteria
Abstract Extracts from five Antarctic lichens (L3, Stereocaulon alpinum L5, Ramalina terebrata L6, Caloplaca sp.; L8, Lecanora sp.; and L17, Caloplaca regalis ) were tested for antimicrobial activities against several clinically important microbes by disk diffusion. The minimum inhibitory concentrat...
