TL;DR: Electron microscopy suggested that the location of the resulting Pd(0) deposits was as expected from the subcellular localization of the particular hydrogenase involved in the reduction process, and Membrane separation experiments established that PD(II) reductase activity is membrane-bound and that hydrogenases are required to initiate Pd (II) reduction.

TL;DR: Microbial precipitation of gold was achieved using Escherichia coli and Desulfovibrio desulfuricans provided with H2 as the electron donor and the concept was successfully applied to recover 100% of the gold from acidic leachate obtained from jewellery waste.

TL;DR: In this paper, a biologically supported nano-Pd contains particles of size ∼5nm and below, as determined using magnetic measurements (SQUID) and EXAFS spectroscopy.

TL;DR: A novel biochemical method based on the sacrificial hydrogen strategy to synthesize bimetallic gold–palladium nanoparticles (NPs) with a core/shell configuration that showed comparable catalytic activity to chemical counterparts with respect to the oxidation of benzyl alcohol, in air, and at a low temperature (90°C).

TL;DR: Five gram negative and two gram positive bacterial strains known for their heavy metal tolerance or ability to reduce metal ions were coated with Pd(0) nanoparticles (NPs) via reduction of soluble Pd (II) ions under H2 following an initial uptake of PdCl4 2without added electron donor (’biosorption’), where the gram negative strains had a 5-fold greater capacity for PD(II).
