Linking Spectral and Electrochemical Analysis to Monitor <i>c‐</i>type Cytochrome Redox Status in Living <i>Geobacter sulfurreducens</i> Biofilms

Abstract

Biofilm synesthesia: A simultaneous spectral and electrochemical analysis reveals the redox status of cytochromes within living electroactive biofilms of Geobacter. The results confirm that the primary electron reservoirs within these biofilms are c-type cytochromes and suggest which cytochromes act as kinetic bottlenecks to electron transfer.
