Electromicrobiology: Electron Transfer via Biowires in Nature and Practical Applications [PDF]
BIO Web of Conferences, 2016 One of the most exciting developments in the field of electromicrobiology has been the discovery of electrically conductive pili (e-pili) in Geobacter species that transport electrons with a metallic-like mechanism.

Using Cathodic Poised Potential Experiments to Investigate Extracellular Electron Transport in the Crustal Deep Biosphere of North Pond, Mid-Atlantic Ridge [PDF]
Frontiers in Environmental Science, 2020 The crustal sub-seafloor covers a large portion of the Earth’s surface but is poorly understood as a habitat for life. It is unclear what metabolisms support the microscopic cells that have been observed, and how they survive under resource limitation ...

Electromicrobiological concentration cells are an overlooked potential energy conservation mechanism for subsurface microorganisms [PDF]
Frontiers in MicrobiologyThermodynamics has predicted many different kinds of microbial metabolism by determining which pairs of electron acceptors and donors will react to produce an exergonic reaction (a negative net change in Gibbs free energy). In energy-limited environments,

Towards bioprocess engineering of cable bacteria: Establishment of a synthetic sediment. [PDF]
MicrobiologyopenIn this study, we successfully cultivated the cable bacteria strain Electronema aureum GS on a newly developed synthetic sediment, marking the first instance of such cultivation on synthetic rather than natural sediment. The combination of this synthetic sediment and a specially designed sediment bioreactor enables reproducible cultivation of cable ...

Extracellular electron transfer genes expressed by candidate flocking bacteria in cable bacteria sediment [PDF]
mSystemsCable bacteria, filamentous sulfide oxidizers that live in sulfidic sediments, are at times associated with large flocks of swimming bacteria. It has been proposed that these flocks of bacteria transport electrons extracellularly to cable bacteria via an

Cable bacteria reduce methane emissions from rice-vegetated soils [PDF]
Nature Communications, 2020 Rice paddies are a major source of the Earth’s atmospheric methane, making these important food crops potent contributors to greenhouse gas emissions. Here the authors show that inoculation of paddies with a particular bacterium could significantly curb ...

Electromicrobiology : a systems perspective. [PDF]
, 2012 The ability of microorganisms to exchange electrons directly with their environment has large implications for our knowledge of industrial as well as for environmental processes. For decades, it has been known that microbes can use electrodes as electron acceptors in microbial fuel cell settings.

, 2021 El agua, además de ser fuente de vida, es un factor indispensable para un desarrollo social, económico y medioambiental. Actualmente, el uso global de agua se ha multiplicado por seis en los últimos 100 años, y continúa aumentando. Lo que antes era un bien de primera necesidad accesible a la mayoría de la población, ahora ha llegado a cotizar en bolsa (
