Evaluation of Cyanobacterial Distributions in Estuary Region of Southeastern India and its Phycoremediation Studies in Industrial Effluent

Cyanobacteria are photo-autotrophs, potential rich organisms gaining interest in all fields. They are almost cosmopolitan in moisture rich environment, holding different adaptations based on their locations and encompass wide potentials which are boon to that ecosystem. Marine cyanobacteria contribute its role in various ways such as energy fuel, food, medicine and also in bioremediation process. The study focused on seasonal distribution of cyanobacteria in Arumuganeri estuary region, Tuticorin district, Tamil Nadu, India. Phycoremediation studies were performed against distillery effluent using marine cyanobacterial isolates which are obtained from the enrichment. Morphological characterization was done. A total of 36 cyanobacterial species belongs to five families were observed in those sites. Among them, the cyanobacterial species such as Spirulina subsalsa, Oscillatoria willei and Lyngbya aestuarii were plays vital role in degradation.
