Identification and phenotypic plasticity of Pseudanabaena catenata from the Svalbard archipelago
A filamentous benthic cyanobacteria, strain USMAC16, was isolated from the High Arctic Svalbard archipelago, Norway, and a combination of morphological, ultrastructural and molecular characterisation (16S rRNA gene sequence) used to identify to species level.
