Cyanobacteria are the largest group of photosynthetic prokaryotes, capable of fixing both atmospheric carbon and nitrogen. They are unique in their widespread occurrence abundance and morphological diversity, similar to gram negative bacteria in their cell structure and biochemistry. Only few studies are available on marine cyanobacteria from mangrove habitats. The present study was therefore, made to analyze the marine cyanobacterial population in mangrove rhizosphere soil. The marine cyanobacterium Phormidium species ARKK2 was isolated from sediments of Vellar mangrove forest situated in south east coast of India. Five spices belonging to family Oscillatoriaceae and Chroococcaceae were identified based on the size and shape and they were Phormidium sp., Oscillatoria willei, Phormidium fragile, Synechococcus elongatus and Gloeocapsa sp., Of the five species, Phormidium sp., were analyzed for 16S rDNA, and their phylogeny.
