DIVERSITY OF CYANOPHYCEAE FROM THE NATAWAD DAM OF NANDURBAR DISTRICT, MAHARASHTRA, INDIA Jayshree Subhash Nayka1, Prem Kumar Gautam2 & Ashish Bharat Valvi3 1-3 Department of Botany, G. T. Patil Arts, Commerce and Science College, Nandurbar jayshreenayak1994@gmail.com premunnat@gmail.com Paper Received On: 25 FEBRUARY 2023 Peer Reviewed On: 28 FEBRUARY 2023 Published On: 01 MARCH 2023 Abstract The present investigation was carried out at the Natawad dam in the Nandurbar District of Maharashtra, India. Blue Green algae are cosmopolitan in distribution. Throughout the investigation, a total of 24 BGA species of 10 genera were identified. The reported BGA species are a) Gloeocapsa punctate b) Chroococcus pallidus c) Chroococcus minutus d) Chroococcus minor e) Microcystis aeruginosa f) Merismopedia marssonii g) Lyngbya aestuarii h) Lyngbya majuscule i) Lyngbya lutea j) Oscillatoria laete-virens var. minimus k) Oscillatoria martini l) Oscillatoria princeps m) Oscillatoria subbrevis n) Oscillatoria perornata o) Oscillatoria terebriformis p) Oscillatoria tenuis q) Oscillatoria chalybae r) Oscillatoria pseudogeminata s) Spirulina major t) Geitlerinema amphibium u) Geitlerinema calcuttensis v) Phormidium uncinatum w) Phormidium willei x) Pseudanabaena catenata etc. During the study of filamentous genera, Oscillatoria was the dominant genus observed.

Introduction The Blue-Green Algae are prokaryotes, which set them apart from other groups in this flora, and are unicellular or filamentous; sometimes form structures that may be seen with the naked eye but commonly need a microscope for identification (Srinivas, M., & Aruna, M. 2016). Cyanobacteria are found in a wide range of aquatic and terrestrial ecosystems, including conditions hot springs, deserts, and Polar Regions (Mohr, K. I., Brinkmann, N., & Friedl, T. 2011), nearly every exposed rock surface on the planet (Budel, B. 2011), On damp rocks, on cement walls, in marine water, streams and lakes etc. (Valvi, A. B., & Gautam, P. K. 2017). Blue-green Algae are the oldest known photosynthetic organism’s component of biological soil crusts (Büdel, et al. 2016). The development of oxygenic photosynthesis altered every face of our planet's appearance. It is believed that the anoxygenic progenitors of cyanobacteria were the first species to develop oxygenic photosynthesis (De Clerck, O., Bogaert, K. A., & Leliaert, F. 2012). Cyanobacteria's agricultural significance in rice production is directly tied to their ability to fix nitrogen and have other beneficial effects on plants and soil (Rajasekaran, A., & Raja, U. 2021).
