Journal ArticleDOI
A new model for electron flow during anaerobic digestion: direct interspecies electron transfer to Methanosaeta for the reduction of carbon dioxide to methane
Amelia-Elena Rotaru,Pravin Malla Shrestha,Fanghua Liu,Minita Shrestha,Devesh Shrestha,Mallory Embree,Karsten Zengler,Colin Wardman,Kelly P. Nevin,Derek R. Lovley +9 more
TL;DR: In this article, a metatranscriptomic analysis of methanogenic aggregates from a brewery wastewater digester, coupled with fluorescence in situ hybridization with specific 16S rRNA probes, revealed that Methanosaeta species were the most abundant and metabolically active methanogens.
Journal ArticleDOI
Promoting direct interspecies electron transfer with activated carbon
Fanghua Liu,Amelia-Elena Rotaru,Pravin Malla Shrestha,Nikhil S. Malvankar,Kelly P. Nevin,Derek R. Lovley +5 more
TL;DR: The results demonstrate that GAC can promote DIET and suggest that stimulation of metabolism in methanogenic digesters can be attributed, at least in part, to the high conductivity of GAC providing better interspecies electrical connections than those that can be forged biologically.
Journal ArticleDOI
Direct Interspecies Electron Transfer between Geobacter metallireducens and Methanosarcina barkeri
Amelia-Elena Rotaru,Pravin Malla Shrestha,Fanghua Liu,Beatrice Markovaite,Shanshan Chen,Shanshan Chen,Kelly P. Nevin,Derek R. Lovley +7 more
TL;DR: M. barkeri is the second methanogen found to accept electrons via DIET and the first meetinghanogen known to be capable of using either H2 or electrons derived from DIET for CO2 reduction, making it a model organism for elucidating mechanisms by which methanogens make biological electrical connections with other cells.
Book ChapterDOI
Geobacter: The Microbe Electric's Physiology, Ecology, and Practical Applications
Derek R. Lovley,Toshiyuki Ueki,Tian Zhang,Nikhil S. Malvankar,Pravin Malla Shrestha,Kelly A. Flanagan,Muktak Aklujkar,Jessica E. Butler,Ludovic Giloteaux,Amelia-Elena Rotaru,Dawn E. Holmes,Ashley E. Franks,Roberto Orellana,Carla Risso,Kelly P. Nevin +14 more
TL;DR: The study of Geobacter species has revealed a remarkable number of microbial physiological properties that had not previously been described in any microorganism, which might contribute to the field of bioelectronics.
Journal ArticleDOI
Promoting Interspecies Electron Transfer with Biochar
Shanshan Chen,Amelia-Elena Rotaru,Pravin Malla Shrestha,Nikhil S. Malvankar,Fanghua Liu,Wei Fan,Kelly P. Nevin,Derek R. Lovley +7 more
TL;DR: The finding that biochar can stimulate DIET may be an important consideration when amending soils with biochar and can help explain why biochar may enhance methane production from organic wastes under anaerobic conditions.
