Description This travel grant allowed a PDRA to visit an American Laboratory and conduct experiments under oxygen-free conditions that showed for the first time that the proteins on a bacteria surface could interact and dissolve a solid mineral.
Exploitation Route Improve microbe-electrode interfaces in order to couple bacteria (and bacterial processes) to electricity.

PI Contribution This collaboration involved the development of techniques to study electron transfer across membranes through outer membrane cytochromes complexes. We developed the technique at UEA, which was then used by the PNNL with guidance from us to look at a range of different systems. The partnership resulted in an extension of funding from the PNNL to continue work until july 2016
Collaborator Contribution The work was performed at PNNL, using their equipment and scientists, but with the advice and support from the UEA team.
