Standardized microbial fuel cell anodes of silica-immobilized Shewanella oneidensis

摘要

Populations of metabolically active bacteria were associated at an electrode surface via vapor-deposition of silica to facilitate in situ characterization of bacterial physiology and bio-electrocatalytic activity in microbial fuel cells.rnMicrobial fuel cells (MFC) convert chemical energy to electrical energy by capitalizing on the metabolic and respiratory processes of particular microbial species. Dissimilatory metal-reducing bacteria such as Shewanella oneidensis will transfer electrons from reduced electron donors (e.g. lactate) to insoluble electron acceptors (e.g. iron and manganese oxides).
