Summary

The potential for various substances to serve as electron shuttles between Fe(III)-reducing microorganisms and insoluble Fe(III) oxides in aquifer sediments was evaluated in order to determine whether abiological mechanisms might play a role in the apparent microbial reduction of Fe(III) in subsurface sediments. Humic substances (humics) and the humics analogue, anthraquinone-2,6-disulfonate (AQDS), which were previously found to stimulate microbial reduction of synthetic poorly crystalline Fe(III) oxide under laboratory conditions, were found to also stimulate the reduction of aquifer Fe(III) oxides by indigenous microorganisms. Electron shuttling via biological reduction of U(VI) or S° followed by abiological reduction of Fe(III) [...]
