      Sewage water contamination is a significant health risk factor that affects plant development, aquatic environment, and human life quality. Among different mitigation strategies, bioremediation is thought to be the most sustainable and cost-effective. Thus, the current study aimed at finding new bacteria with a high potential for reducing sewage water contaminants, as well as heavy metal sorption capabilities. Only one bacterium (Strain DDN) was selected from a large number of isolated bacteria due to its high proteolysis and antibacterial activity. This bacterium was identified using biochemical and 16S rDNA-based molecular analysis. The phylogenetic tree revealed the strongest resemblance to Bacillus aryabhattai strain QH 16-25 (here called as Bacillus aryabhattai DDN). Furthermore, the biodegradation capability of bacteria was assessed, and it was discovered that there was a significant reduction in certain pollution indicating parameters including BOD (65.81%), COD (58.02%), alkalinity (53.65%), hardness (56.91%), calcium (71.56%) ammonia (43.34%) and orthophosphate (40.37%) content within 14 days. Moreover, the concentration of heavy metals, such as Hg, Cd, Cr, Fe and Mn decreased up to 61.69, 60.77, 88.67, 24.69, and 81.95%, respectively, when compared to the initial concentration. Thus, this novel bacterium proved to be a multi metal tolerant and a potent bioremediatory tool for environment safeguard. [ABSTRACT FROM AUTHOR]
