This study investigates the antimicrobial activities of ethyl alcohol extracts from various moss species, namely Grimmia pulvinata (Hedw.), Pleurochaete squarrosa (Brid.), Bryum capillare (Hedw.), Grimmia orbicularis (Bruch), Oxyrrhynchium hians (Hedw), Homalothecium lutescens (Hedw.), Hypnum cupressiforme (Hedw.), and Palustriella falcate (Hedw.), against 15 strains comprising 5 gram-positive bacteria, 7 gram-negative bacteria, and 3 yeast. Following the tests, it was determined that Oxyrrhynchium hians (Hedw.), Homalothecium lutescens (Hedw.), Hypnum cupressiforme (Hedw.), and Palustriella falcate (Hedw.) moss species exhibited antimicrobial activity. Notably, mosses displayed the highest antimicrobial activity against the Staphylococcus aureus strain among the strains used in this study.
