Cyanobacteria in thermal spring environments - Diversity and ecology

Cyanobacteria collected from thermal springs of Greece were isolated into
non-axenical unicultures. The main target of the thesis was the polyphasic
taxonomic aproach of the 34 isolated strains. We combined classical taxonomy
with molecular techniques and phylogenetic trees were bult with different
methods like maximum parsimony, maximum likelihood and bayesian inference. Our
analysis indicated at least 13 new cyanobacterial taxa at the genus level.
Moreover, 4 isolated strains were sequenced for their whole genome and the de
novo assembly and genome mining approach showed many interesting secondary
metabolites, while the vast majority of the recognised proteins had no match to
the known protein families. Finally, water samples and cyanobacterial mats were
analyzed for nutrients and heavy metal concentration.
