Cyanobacteria (Blue-green algae) is a photosynthetic bacteria found in both freshwater and marine habitats. Some of the earliest known life forms on Earth are cyanobacteria, which are also thought to be the first species to produce oxygen as a consequence of photosynthesis. They are significant primary producers in aquatic habitats, giving other creatures energy and nutrients. In industrial and agricultural activities including wastewater treatment, bioremediation, and the creation of biofuels, they are also employed. Algal blooms were tracked as part of the Open Filed Collective Project, and each month their diversity is recorded. The freshwater lake near Adilabad and the Mancherial district is being monitored as part of this study by taking water samples, which are then analyzed for physiological features like pH, daytime temperature, the presence of algae in the water, and odor. A spectrophotometer is used to determine the number of algae in the water, and a foldscope and compound microscope are used to view the cells. In order to develop the algae species in tap water, growth promoters like CaCO3 and NaNO3 are added. Following filtering, the algal mat is dried by air. The algal dry mat is pulverized and extracted using a liquid-solid mixture of methanol and ether (7:3). Chromatography is then used to examine the chemicals recovered from the extract using the solvent mixture.
