Abstract
A previous feasibility study showed a novel bionanocatalyst catalysing unexpected degradation of recalcitrant PCBs. Along with reductive dehalogenation (RD) an unexpected fragmentation of the PCB molecule occurred, attributable to unique properties of Pd nanoclusters, biosynthesised by initial biosorption of Pd(II) followed by reduction to Pd(0) under H2 via the hydrogenase activity of sulfate-reducing bacteria. The supported, templated, bionanoclusters (approximately 5 nm) form a completely new class of catalyst. The objectives of this proposal are to investigate the mechanism of PCB breakdown with respect to the organic fragments produced, the order of events (RD or fragmentation first), and application to PCB remediation from used transformer oils
