Randomized trial evaluates metal removal efficacy in contaminated sites, indicating promising bioremediation applications.

This research aims to isolate and characterize bacteria from tannery effluents that can tolerate and potentially remediate lead and cadmium.
Isolated 72 lead-tolerant and 52 cadmium-tolerant bacterial strains from tannery effluents using metal-supplemented LB agar.
Determined Minimum Inhibitory Concentrations (MICs) for Pb2+ (4000 ppm) and Cd2+ (250 ppm).
Conducted genomic and proteomic analyses to identify resistance mechanisms and functional traits.
Achieved lead removal efficiency of 93.91% and cadmium removal efficiency of 89.66%.
Identified K. pneumoniae with strong plant growth-promoting traits and potential for bioremediation.
Diverse metal-responsive proteins detected, with cusR identified as a key resistance gene in dominant strains.
