Diversity and bioprospecting of fungal communities associated with endemic and cold-adapted macroalgae in Antarctica
TLDR
The results suggest that the endemic and cold- Adapted macroalgae of Antarctica shelter a rich, diversity and complex fungal communities consisting of a few dominant indigenous or mesophilic cold-adapted species, and a large number of rare and/or endemic taxa, which may provide an interesting model of algal–fungal interactions under extreme conditions as well as a potential source of bioactive compounds.

Yeasts from macroalgae and lichens that inhabit the South Shetland Islands, Antarctica.
TLDR
Results suggest that Antarctic phyco and lichensphere represent a huge substrate for cold-adapted yeasts and enhanced the knowledge of the microbiota from extreme environments.

Isolation of fungi associated with macroalgae from maritime Antarctica and their production of agarolytic and carrageenolytic activities
TLDR
The results indicated that the Antarctic macroalgae shelter saprobe fungi that produce enzymes with the potential to degrade algal biomass and might release essential nutrients into the Antarctic Ocean.

The Ecological Role of Micro-organisms in the Antarctic Environment
TLDR
Combined, these studies show that members of the cyanobacteria are critical carbon and nitrogen regulators and are essential for making nutrients available to associated community members.
