WebSep 6, 2024 · As variability in our solid-phase electron shuttling capacity assays was high, it may be that our treatments were too short in duration to manifest consistent changes in solid phase redox state. In contrast, pore water character responded to PFG and Eh7, and represented a rapid and non-destructive way to assess changes in redox conditions. WebNov 10, 2011 · This review will focus on respiratory electron transfer from the surface of the bacterial cell to extracellular substrates. Shewanella sp. secrete redox-active flavin compounds able to transfer electrons between the cell surface and substrate in a cyclic fashion—a process termed electron shuttling. The production and secretion of flavins …
