Within the wide biodiversity that is found in the bacterial world, Cyanobacteria represents a
unique phylogenetic group that is responsible for a key metabolic process in the biosphere …

Cyanobacteria are an ancient and morphologically diverse group of photosynthetic
prokaryotes, which were the first to evolve oxygenic photosynthesis. Cyanobacteria are …

Freshwater cyanobacteria produce several bioactive secondary metabolites with diverse
chemical structure, which may achieve high concentrations in the aquatic medium when …

The vegetative cells of the filamentous cyanobacterium Nostoc punctiforme can differentiate
into three mutually exclusive cell types: nitrogen-fixing heterocysts, spore-like akinetes, and …

Akinetes are resting spore-like cells formed by some heterocyst-forming filamentous
cyanobacteria for surviving long periods of unfavourable conditions. We studied the …

Stress conditions, such as a block in fatty acid synthesis, signal bacterial cells to exit the cell
cycle. Caulobacter crescentus FabH is a cell-cycle-regulated β-ketoacyl-acyl carrier protein …

Cyanobacterial blooms represent a major problem in reservoirs that are used for potable
water supplies. The El Limón reservoir is one of the main reserves of water for consumption …

Acclimation and flexible response mechanisms are survival adaptations allowing prokaryotic
cells to colonize diverse habitats and maintain viability in nature. Lack of water significantly …

Aphanizomenon ovalisporum is a planktonic nostocalean cyanobacterium with increasing
research interest due to its ability to produce the potent cytotoxin cylindrospermopsin and its …

Nostocalean cyanobacteria are known to proliferate abundantly in eutrophic aquatic
ecosystems, and to produce several cyanotoxins, including anatoxin-a. In this study, we …
