Electrical transport along bacterial nanowires from Shewanella oneidensis MR-1.
Bacterial nanowires are extracellular appendages that have been suggested as pathways for electron transport in phylogenetically diverse microorganisms, including dissimilatory metal-reducing bacteria and photosynthetic cyanobacteria. However, there has been no evidence presented to demonstrate electron transport along the length of bacterial nanowires. Here we report electron transport measure...
متن کاملMicrobial reduction and precipitation of vanadium by Shewanella oneidensis.
Shewanella oneidensis couples anaerobic oxidation of lactate, formate, and pyruvate to the reduction of vanadium pentoxide (V(V)). The bacterium reduces V(V) (vanadate ion) to V(IV) (vanadyl ion) in an anaerobic atmosphere. The resulting vanadyl ion precipitates as a V(IV)-containing solid.
متن کاملStandardized microbial fuel cell anodes of silica-immobilized Shewanella oneidensis.
Populations of metabolically active bacteria were associated at an electrode surface via vapor-deposition of silica to facilitate in situ characterization of bacterial physiology and bio-electrocatalytic activity in microbial fuel cells.
متن کاملEngineering Shewanella oneidensis enables xylose-fed microbial fuel cell
BACKGROUND The microbial fuel cell (MFC) is a green and sustainable technology for electricity energy harvest from biomass, in which exoelectrogens use metabolism and extracellular electron transfer pathways for the conversion of chemical energy into electricity. However, Shewanella oneidensis MR-1, one of the most well-known exoelectrogens, could not use xylose (a key pentose derived from hydr...
متن کاملSERS spectroscopy and SERS imaging of Shewanella oneidensis using silver nanoparticles and nanowires.
Facile and reproducible SERS signals from Shewanella oneidensis were obtained utilizing silver nanoparticles (AgNPs) and silver nanowires (AgNWs). Additionally, SERS images identify the distribution of SERS hot-spots. One important observation is the synergistically enhanced SERS signal when AgNPs and AgNWs are used in conjunction, due to constructively enhanced electromagnetic field.
