Diversity and bioprospecting of fungal communities associated with endemic and cold-adapted macroalgae in Antarctica
Abstract We surveyed the distribution and diversity of fungi associated with eight macroalgae from Antarctica and their capability to produce bioactive compounds. The collections yielded 148 fungal isolates, which were identified using molecular methods as belonging to 21 genera and 50 taxa. The mos...
