Abstract:
In the current investigation analysed for diversity of cyanobacteria from east coast environment and physicochemical parameters of soil were analysed from the four different study sites. The soil physicochemical character like pH, salinity, Electrical conductivity, Organic Carbon, Organic Matter, Available Nitrogen, Phosphorus, Zinc, Copper, Iron, Manganese, Calcium, Magnesium and Potassium were experimently performed from Kelathottam, Mallipattinam, Manora and Sethupasathiram of thanjavur district conducted. The soil has extraordinary content of nutrients were presented in keelathottam area when compared with other places. The isolation of cyanobacteria like Anabaena azollae, Chroococcus limneticus, Dermocarpa sp., Gloeocapsa magma, Johannesbaptistia sp., Gloeothece sp., Katagnymene sp., Microcoleus vaginatus, Myxosarcina sp., Nostoc muscorum, Oscillatoria spongeliae, Plectonema phormidiuodes, Pseudanabaena sp., Spirulina sp., Stigonema sp., Symploca sp., Synechococcus sp., Trichodesmium sp and Xenococcus sp were recorded from four different places of Keelathottam, Mallipattinam, Monera and Sethupasathiram of Thanjavur district were analysed. Among the four places the keelathottam has maximum number of colonies and species recorded than the other places. The diversity of cyanobacteria has excellent microbial resources of our country and back bone of the marine environment.
