Development and characterisation of self-assembled graphene hydrogel-based anodes for bioelectrochemical systems
(Royal Society of Chemistry, 2018-08)
In this work, we report a simple and scalable method to produce high efficiency 3D graphene-based electrodes (GH) for bioelectrochemical systems. GH were obtained by self-assembly of graphene oxide, through slow reduction ...
Thermally activated charge transport in microbial protein nanowires
(2016-03-24)
The bacterium Geobacter sulfurreducens requires the expression of conductive protein filaments or pili to respire extracellular electron acceptors such as iron oxides and uranium and to wire electroactive biofilms, but the ...
Simulación de una cámara anódica y el efecto de su composición sobre la e ciencia de una celda de combustible microbiana
(Universidad Nacional de Colombia - Sede Bogotá, 2019-10-17)
Se desarrolló un modelo de la cámara anódica en una celda de combustible microbiana para mejorar la comprensión de los fenómenos biológicos que suceden al interior de dicho dispositivo. La posibilidad de transferir electrones ...
Estudo computacional de estrutura atômica e eletrônica em proteínas eletroativas de bactérias do gênero Geobacter
(Universidade Estadual Paulista (Unesp), 2018-02-28)
A pilina é um peptídeo produzido pela bactéria redutora de metais Geobacter sulfurreducens. Este peptídeo compõe um sistema biológico que tem atraído a atenção de pesquisadores, devido às suas propriedades condutoras ...
Effect of soil chemical fertilization on the diversity and composition of the tomato endophytic diazotrophic community at different stages of growth
(Springer, 2020-12)
The aim of this work was to gain a more comprehensive and perspicacious view of the endophytic diazotrophic community (EDC) of tomato plant bacteria and assess the effects of chemical fertilization and the plant phenologic ...
Respiratory Au nucleation and microelectrode techniques reveal key features of bacterial conductive matrix
(Royal Society of Chemistry, 2020-10)
The previously reported relay network conductivity model has shed some light on the structure and mechanisms behind long-distance extracellular electron transfer (EET) in Geobacter biofilms. The structuration of c-type ...
Bacterial Diversity in Calcium Carbonate Paleo Accretions ( Tosca ) in the Southern Pampas, Argentina
(Taylor & Francis, 2021-08)
Paleosoil accretions of carbonates in the Tandilia system (Southern Pampas, Argentina) dated to the lower/middle Pleistocene age are locally referred to as tosca. The characterization of this indurated layer of carbonates ...
Identificação da presença de combustíveis em subsuperfície através de técnicas de biologia molecular
(Florianópolis, SC, 2012)
