Cuttack district, one of Odisha's oldest, is known as the Millennium City and located at 20.4625° N latitude and 85.8830° E longitude. It was selected for our research due to its high pollution levels and the prevalence of algae in contaminated water. In this regards, four collection sites were chosen: S1 (Badambadi), S2 (Jagatpur), S3 (Nischintakoili), and S4 (Salipur). Samples were collected in sterilized falcon tubes and analysed for physicochemical parameters viz. DO, pH, temperature in the laboratory. Using a Leica dm 750 microscope and Leica ICC50 HD camera, we identified algal species based on their morphological characteristics with the help of monographs and algal databases. The study revealed significant algal diversity of 30 species under 5 divisions (Cyanobacteria, Bacillariophyta, Charophyta, Chlorophyta, Euglenozoa), 15 orders including 19 families, and 22 genera. Moreover, the present study revealed that Bacillariophyta showed the highest diversity among others. Specifically, we found 6 species of Cyanobacteria, 16 of Bacillariophyta, 2 of Charophyta, 5 of Chlorophyta, and 1 of Euglenozoa. Notably, three species were recorded for the first time in India namely Kamptonema cortianum, Halamphora veneta, Tabularia fasciculata and three in Odisha such as Micractinium pusillum, Navicula sacrophagus, Synedra ulna. Furthermore, our study suggested that these algal species may be exploited as a promising feedstock for future biofuels and biodiesel production as well as phycoremediation and therapeutic intervention in the future.
