Lack of Specificity in Geobacter Periplasmic Electron Transfer
Many inner and outer membrane cytochromes used by Geobacter for electron transfer to extracellular acceptors have specific functions. How these are connected by periplasmic carriers remains poorly understood. G.

Coastal sediments are rich in conductive particles, possibly affecting microbial processes for which acetate is a central intermediate. In the methanogenic zone, acetate is consumed by methanogens and/or syntrophic acetate-oxidizing (SAO) consortia.

Diverse reductive dehalogenases are associated with Clostridiales-enriched microcosms dechlorinating 1,2-dichloroethane [PDF]
The achievement of successful biostimulation of active microbiomes for the cleanup of a polluted site is strictly dependent on the knowledge of the key microorganisms equipped with the relevant catabolic genes responsible for the degradation process.

Temperature, inocula and substrate: contrasting electroactive consortia, diversity and performance in microbial fuel cells [PDF]
The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and ...

Effect of surface roughness, biofilm coverage and biofilm structure on the electrochemical efficiency of microbial cathodes [PDF]
Biofilms of Geobacter sulfurreducens were formed under chronoamperometry at −0.5 V and −0.6 V vs. Ag/AgCl on stainless steel cathodes and tested for fumarate reduction.

Biochemical Capacitance of Geobacter Sulfurreducens Biofilms
AbstractAn electrical model able to decouple the electron pathway from microbial cell machinery impedance terms is introduced. In this context, capacitance characteristics of the biofilm are clearly resolved. In other words, the model allows separating, according to the advantage of frequency and spectroscopic response approach, the different terms ...
