Cyanobacteria of Polar Regions: Focus of the BCCM/ULC Culture Collection
In the Polar Regions, Cyanobacteria represent key primary producers and are the main drivers of the food webs in a wide range of aquatic to terrestrial habitats. They build benthic microbial mats in lakes and soil crusts in terrestrial biotopes. They may present interesting features to survive freez...
