Resting cells of Escherichia coli, immobilized in a flow-through bioreactor, coupled the oxidation of formate or hydrogen to Tc(VII) reduction and removal from solution. Cells, pregrown anaerobically in a hollow-fiber membrane bioreactor, were challenged with 50 ยตM Tc-(VII) in a carrier solution of
Immobilized cells of a Cifrobacfer species scavenge cadmium with high efficiency from challenge flows containing CdZ+. Metal uptake by the cells is mediated by a cellbound phosphatase which liberates inorganic phosphate from an organic phosphate to precipitate cadmium as cell-bound metal phosphate.
