Isolation and bioassay screening of fungal endophytes from North Atlantic marine macroalgae
Abstract Endophytic fungi of marine macroalgae and the bioactive chemicals they produce have not been widely explored or documented. In this study, fungal endophytes were isolated from four species of brown, three species of red, and two species of green marine algae collected from the Shetland Isla...
