The objectives of the present study were twofold: physicochemical characterization of PCBs from e-waste, viz. mobile phone, digital video disc (DVD) player, inverter, and subsequent assessment of bioleaching of selected metals from high-grade PCB. Cu was the most abundant metal among base metals, while content of Zn was high in mobile phone PCB. Thus, mobile phone PCB was selected as high-grade material and was subjected to bioleaching using pure culture of Acidiphilium acidophilum, with and without lemon juice with citric acid having chelating activity to simulate hybrid and conventional conditions, respectively. Results indicated increased recovery of both the metals in hybrid approach. Under hybrid condition, the maximum concentrations of Cu and Zn leached were 2.419 mg/L and 1.272 mg/L, respectively, while it was 0.424 and 0.132 mg/L in conventional approach at 15 days. These findings highlight potential of hybrid bioleaching in efficient metal recovery from e-waste.
