CYANOBACTERIA IN ANTARCTICA: A MULTIDISCIPLINARY STUDY
Antarctic cyanobacteria biodiversity was investigated at various levels including the morphological, genetic and physiological aspects. Cyanobacteria were collected in Antarctica during the Austral Summer Cruise 2004; the strains were isolated from South polar lakes sediments, soil and liken associa...

Antarctic cyanobacteria biodiversity was investigated at various levels including the morphological, genetic and physiological aspects.

The strains belong to the genera of Nostocales and Oscillatoriales were morphologically identified by microscopy. The fatty acid composition varied among the strains with a relatively high quantity of polyunsaturated fatty acid production. A first genetic investigation by RAPD markers was performed. Cyanobacteria strains were also identified by ITS and TrnL sequencing.
