Abstract
This study compared the bacteria in the Yamuna River in India and the Mississippi River in the USA. Water samples were taken from 11 sites (2 in the Mississippi River and 9 in the Yamuna River). The bacteria were identified using 16S rRNA gene sequencing. Some phyla such as Proteobacteria and Bacteroidetes were seen in abundance regardless of country. However, principal-component analysis showed three distinct groupings: Mississippi/Ganga/Tons and other Yamuna River locations (7 sites), Yamuna River at Delhi (2 sites), Yamuna River below Glacier (2 sites) Additionally, the Yamuna River below Glacier had the highest bacterial diversity, with a Shannon index of 5.1 and a Simpson index of 0.986 when compared to both the Yamuna River below Glacier (Shannon p-value: <0.0001, Simpson p-value: <0.0001) and the Yamuna River at Delhi (Shannon p-value: <0.0001, Simpson p-value: <0.0001).
