Abstract

Abstract

En 中文
• Fe3+ and NO3- enhance Cr(VI) bioreduction and cyts c-electron transmission. • Fe3+ show higher Cr(VI) bioreduction than NO3- even with lower oxidability. • Fe3+ and NO3- promote “nanowire” growth (stimulation effect: Fe3+ > NO3-). • Cyts c in inner and outer membranes respond synchronously to electron acceptors. • Cyts c in EPS and cell membrane respond inconsistently to electron acceptors.
