Occurrence of hopanoid lipids in anaerobicGeobacterspecies [PDF]
Geobacter metallireducens and G. sulfurreducens have been classified as strictly anaerobic bacteria which grow and thrive in subsurface and sediment environments. Hopanoids are pentacyclic triterpenoid lipids and are important for bacterial membrane stability and functioning.

Ultra microelectrodes increase the current density provided by electroactive biofilms by improving their electron transport ability [PDF]
Electroactive biofilms were formed from garden compost leachate on platinum wires under constant polarisation at -0.2 V vs. SCE and temperature controlled at 40 C.

Conductivity of individual Geobacter pili
Measurements of the conductivity of hydrated individual pili of Geobacter sulfurreducens that were not subjected to chemical fixation revealed conductivity along cytochrome-free regions comparable to conducting organic polymer nanowires of similar diameter.

Fluctuations in species-level protein expression occur during element and nutrient cycling in the subsurface. [PDF]
While microbial activities in environmental systems play a key role in the utilization and cycling of essential elements and compounds, microbial activity and growth frequently fluctuates in response to environmental stimuli and perturbations.

DSA to grow electrochemically active biofilms of Geobacter sulfurreducens [PDF]
Biofilms of Geobacter sulfurreducens were grown on graphite and on dimensionally stable anodes (DSA) in medium that did not contain any soluble electron acceptor.
