【 摘 要 】

Work performed under the Independent Research and Development project 'Bioelectrochemical Process Development' using Shewanella Oneidensis MR-1 henceforth MR-1, a model dissimilitory metal reducing (DMRB) bacteria successfully demonstrates the following: MR-1 transfers electrons by hydrogen oxidation to solid phase electrodes; MR-1 can act as an electron transfer agent when attached to a solid metal electrode surface - a modified electrode has been developed and tested; MR-1 transfers electrons from solution to a solid electrode. DMRB grow by transferring electrons to insoluble metals. When bacteria oxidize organic compounds or hydrogen this results in electron flow from the bacterial cell for the purpose of cellular energy production. Extracellular electron transfer to solid terminal electron acceptors permits coupling this oxidation process to electrodes.
