The novel marine cyanobacterium Nunduva sanctimaloensis sp. nov. (Nostocales, Cyanobacteria) from rocky shores and its reproduction through modified monocytes

Rocky intertidal regions are diverse as they provide many unique habitats for the growth of cyanobacteria. From outcrops battered by waves, tidal pools, and periods desiccations due to tides, these offer distinct environments much their cyanobacterial diversity remains unexplored. To help elucidate cyanobacteria from this habitat, one nostocalean cyanobacterium Brittany, France was isolated cultured. Typical morphological features including filaments with heteropolar trichomes, basal or intercalary heterocytes, false branching, long hyaline apical hairs suggested genus Nunduva. The combination 16S rRNA gene 16S-23S internal transcribed spacer (ITS), along diagnosable characteristics supports a taxon previously described species. Herein, novel branching Nunduva sanctimaloensis sp. nov. is its reproduction through modified monocytes.
