The diversity within the genus Aphanizomenon (Nostocales, Cyanobacteria) is still controversial and more studies are needed to clarify its heterogeneity. Aphanizomenon strains isolated from the eutrophic shallow Vela Lake (Centralwestern Portugal) during bloom formation in summer months from 2001 to 2007 were characterized combining phenotypic and molecular approaches. The molecular affiliation...

A new species of heterocytous cyanobacterium Dulcicalothrix alborzica sp. nov. (Calotrichaceae) was isolated from Iran and described following a polyphasic approach. Morphological examination indicated that the strain, initially called "Alborzica", belonged to genus Calothrix. Nonetheless, 16S rRNA gene analysis showed "Alborzica" were within cluster. In order confirm taxonomic position this ta...

Cyanobacteria are photosynthetic, gram negative, and diverse group of prokaryotic organisms, inhabiting a wide range habitats including caves. This study was aimed to isolate identify cyanobacteria in selected caves Bulabog Putian National Park, Dingle, Iloilo, Western Visayas, Philippines. Based on morphology 16S rRNA gene sequence analysis six strains were identified. The homology search by B...
