Microbial biominers: Sequential bioleaching and biouptake of metals from electronic scraps

MicrobiologyOpen, 2022
Electronic scraps (e‐scraps) represent an attractive raw material to mine demanded metals, as well as rare earth elements (REEs). A sequential microbial‐mediated process developed in two steps was examined to recover multiple elements. First, we made use
