LARGER DIATOM FLORA ISOLATED AND IDENTIFIED FROM THE NORTHEAST PELAGIC SEACOAST OF MARAKKANAM, TAMIL NADU, INDIA

Diatoms representing aquatic phototrophs play major role in biogeochemical cycle of silica and fixes global carbon. In the present study the larger marine diatoms were isolated and identified from the Marakkanam sea coast, North East of Tamil Nadu, India. The diatoms were identified and classified using both traditional and morphological methods. The isolation of micro-algae was done using agar plating technique (2% agar in F/2 medium).The diatoms isolated from the coast were dominated by three classes belonging to Bacillariophyceae, Mediophyceae and Coscinodiscophyceae. About 12 genera and 14 species of larger diatoms were isolated and identified in the current study which emphasis the species abundance of the Marakkanam coast and their rich nutritional profile.
