Cyanobacteria played an important role in the evolution of Early Earth and the biosphere.
They are responsible for the oxygenation of the atmosphere and oceans since the Great …

Alcaligenes eutrophus CH34 is the main representative of a group of strongly related strains
(mostly facultative chemolithotrophs) that are well adapted to environments containing high …

The cyanobacterial genus Arthrospira appears very conserved and has been divided into
five main genetic clusters on the basis of molecular taxonomy markers. Genetic studies of …

The thermophilic cyanobacterial strain, PCC7518, originally identified as ‘Mastigocladus
laminosus HTF’ does not show branchings or heterocysts. The absence of branchings supports …

The oxygenic photosynthetic procaryotes comprise a single taxonomic and phylogenetic
group (see master phylogenetic tree of the Bacteria). In the last edition of the Manual, two …

Molecular biology has provided new tools to decipher genetic information and can be used
in attempts to reconstruct the evolution of organisms and improve their taxonomy. In the …

We isolated 59 strains of cyanobacteria from the benthic microbial mats of 23 Antarctic lakes,
from five locations in two regions, in order to characterize their morphological and …

For the first time, the cyanobacterial diversity from microbial mats in lakes of Eastern
Antarctica was investigated using microscopic and molecular approaches. The present study …

The purpose of this chapter is to identify the major cyanobacterial lineages by phylogenetic
analysis, and to show why it is premature, for this edition of the Manual, to treat the taxonomy …

Understanding the enormous diversity of microbes, their multiple roles in the functioning of
ecosystems, and their response to large-scale environmental and climatic changes, are at the …
