Mechanistic stratification in electroactive biofilms of Geobacter sulfurreducens mediated by pilus nanowires

The roles played by cytochromes and conductive filamentous appendages (pili) in the electrical conductivity of Geobacter bacterial biofilms are controversial. Here, Steidl et al. present evidence that both mechanisms cooperate in thin biofilms, while pili are important for conductivity across thicke...
