Metal tolerance and biosorption capacities of bacterial strains isolated from an urban watershed.

ABSTRACT: Rapid industrialization and urbanization have led to widespread metal contamination in aquatic ecosystems. This study explores the metal tolerance and biosorption characteristics of four bacterial strains (Serratia sp. L2, Raoultella sp. L30, Klebsiella sp. R3, and Klebsiella sp. R19) isolated from Saint Clair River sediments. These strains effectively removed various metal cations (As³⁺, Pb²⁺, Cu²⁺, Mn²⁺, Zn²⁺, Cd²⁺, Cr⁶⁺, and Ni²⁺) in single and multi-metal solutions. Minimum inhibitory concentration (MIC) assays revealed strain-specific variations in metal tolerance, with L2 and L30 exhibiting higher tolerance. Surprisingly, R3 and R19, despite lower tolerance, demonstrate
