Spatially Resolved Electron Transport through Anode‐Respiring Geobacter sulfurreducens Biofilms: Controls and Constraints. Issue 10 (21st April 2021) - He, Xiaojia
Abstract: Invited for this month's cover picture is the group of Prof. Christof Meile at the University of Georgia, USA and Prof. Victoria Orphan at the California Institute of Technology, USA. The Front Cover shows characteristic images of G. sulfurreducens biofilms on the anode surface (gray), the distribution of anabolic activity (yellow=high, blue=low), and the equation central to the description of electron transfer and simulated activity profiles.

Abstract : "We report on a spatially resolved model describing the direct electron transfer process in Geobacter sulfurreducens biofilms, experimentally validated using stable isotope ( 15 N) probing with nanoSIMS. Our work indicates that the electric potential and pH both control cellular metabolism. Model simulation results support the presence of two activity modes in G. sulfurreducens biofilms, which allows G. sulfurreducens cells to respond to the decreasing external electric potential…" Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
