Abstract– The Yamuna River, revered as a holy river, faces severe pollution due to human activities, including waste dumping and industrial discharge. This contamination has rendered its water unsafe, raising significant concerns about pathogenic bacteria that can cause various diseases. This study collected water samples from the Kalindikunj barrage in Delhi NCR to isolate bacteria using LB agar media. The isolates were exposed to heavy metals, including Arsenic, Nickel Chloride, and Stannous Chloride, to assess their tolerance levels. Results indicated that bacteria from sample S3 exhibited maximum tolerance to Arsenic at 0.1 mM and minimum at 0.3 mM, while similar patterns were observed for other metals. Sample S4 showed maximum tolerance to Arsenic and other heavy metals at 0.1 mM, with varying minimum tolerances. These findings suggest that the identified heavy metal-tolerant bacteria could be valuable for bioremediation efforts to restore the Yamuna River’s health.
