Modeling biofilms with dual extracellular electron transfer mechanisms [PDF]

Physical Chemistry Chemical Physics, 2013
Electrochemically active biofilms have a unique form of respiration in which they utilize solid external materials as terminal electron acceptors for their metabolism. Currently, two primary mechanisms have been identified for long-range extracellular electron transfer (EET): a diffusion- and a conduction-based mechanism.

Mechanisms of Bacterial Extracellular Electron Exchange. [PDF]

, 2016
The biochemical mechanisms by which microbes interact with extracellular soluble metal ions and insoluble redox-active minerals have been the focus of intense research over the last three decades. The process presents two challenges to the microorganism;

Two Routes for Extracellular Electron Transfer in Enterococcus faecalis [PDF]

Journal of Bacteriology, 2020
The transfer of reducing power in the form of electrons, generated in the catabolism of nutrients, from a bacterium to an extracellular acceptor appears to be common in nature. The electron acceptor can be another cell or abiotic material.

Isolation, identification and characterization of an electrogenic microalgae strain. [PDF]

PLoS ONE, 2013
Extracellular electron transfer involving microbes is important as it closely reflects the ability of cells to communicate with the environment. However, there are few reports on electron transfer mechanisms of pure microalgae and a lack of any model ...

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism

Modular engineering to increase intracellular NAD(H/+) promotes rate of extracellular electron transfer of Shewanella oneidensis

Nature Communications, 2018
A bottleneck for the application of bioelectrochemical systems is the slow rate of extracellular electron transfer. Here the authors use a synthetic biology approach to redirect metabolic flux to NAD+ biosynthesis, which enhances the intracellular ...
