Isolation and characterization of a novel electrogenic bacterium, Dietzia sp. RNV-4
(Public Library of Science, 2017-02)
Electrogenic bacteria are organisms that can transfer electrons to extracellular electron acceptors and have the potential to be used in devices such as bioelectrochemical systems (BES). In this study, Dietzia sp. RNV-4 ...
C-type cytochromes wire electricity-producing bacteria to electrodes
(Wiley VCH Verlag, 2008-06-09)
(Figure Presented) Down to the wire: electro-active bacteria that exchange electrons with solid electrodes are studied by electrochemical and infrared techniques. The approach allows the identification of cell-surface ...
Performance of planar and cylindrical carbon electrodes at sedimentary microbial fuel cells
(Elsevier, 2012-12)
This paper presents data obtained using an indigenous microbial community contained in anaerobic sediments (mud) collected from the shore of the Río de La Plata River (South America). After the sedimentary microbial fuel ...
Opportunities behind the unusual ability of Geobacter sulfurreducens for exocellular respiration and electricity production
(Royal Society Of Chemistry, 2011-05-11)
The possibility to improve the connection of cells to the electrode is significant for microbial fuel cell technology. In this communication we demonstrate that an improved connection can be made by controlling the ...
ATR-SEIRAs characterization of surface redox processes in G. sulfurreducens
(Elsevier, 2009-05-09)
In this work we report on the occurrence of at least two different redox pairs on the cell surface of the electrogenic bacteria Geobacter sulfurreducens adsorbed on gold that are expressed in response to the polarization ...
Sorting the main bottlenecks to use paper-based microbial fuel cells as convenient and practical analytical devices for environmental toxicity testing
(Elsevier, 2021-02)
Three of the primary bottlenecks, which should be consider for practical, point-of-need use of microbial fuel cell (MFC) analytical devices were surpassed in this work: i) the use of a diffusive barrier, hence, an electrogenic ...
Identificación molecular de bacterias electrogénicas a partir de la biopelícula anódica de celdas de combustible microbiana para la producción de bioelectricidad.
(Escuela Superior Politécnica de Chimborazo, 2020-02-13)
This degree work's main aim was to perform the molecular identification of electrogenic bacteria from the anodic biofilm of microbial fuel cells that were developed from soil samples coming from the Andeans high lands of ...
Generación de electricidad en mutantes de Escherichia coli de la producción de NADH y NADPH
(Universidad de Chile, 2018)
1.- RESUMEN
Durante la generación de electricidad en sistemas de Celda de Combustible Microbiológicas (MFC, por su sigla en inglés), se han manipulado distintas vías metabólicas para generar un aumento en la bioelectricidad, ...
Mecanismos de absorção de aminoácidos e oligopeptídios. Controle e implicações na dietoterapia humana
(1999-12-01)
The mechanisms involved in the absorption of amino acids and oligopeptides are reviewed regarding their implications in human feedings. Brush border and basolateral membranes are crossed by amino acids and di-tripeptides ...
Analytical applications of microbial fuel cells. Part II: Toxicity, microbial activity and quantification, single analyte detection and other uses
(Elsevier, 2014-05-09)
Microbial fuel cells were rediscovered twenty years ago and now are a very active research area. The reasons behind this new activity are the relatively recent discovery of electrogenic or electroactive bacteria and the ...
