Charge transfer (CT) is a very important issue in the design of biosensors and biofuel cells. Some nanomaterials can be applied to facilitate CT these bioelectronics-based devices. In this review, we overview some mechanisms and/or pathways that are most frequently established between redox enzymes electrodes. Facilitation indirect by application electrochemical enzymatic More sophisticated still rather rarely observed direct charge (DCT), which often addressed as electron (DET), therefore, DCT/DET also targeted discussed review. The conducting polymers (CPs) for immobilization facilitation during cells overviewed. Significant attention paid various ways synthesis such polyaniline, polypyrrole, polythiophene poly(3,4-ethylenedioxythiophene). CP-based sensors discussed, taking into account not only

Extracellular electron transfer powers flavinylated extracellular reductases in Gram-positive bacteria

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(52), P. 26892 - 26899

Published: Dec. 9, 2019

Mineral-respiring bacteria use a process called extracellular electron transfer to route their respiratory transport chain insoluble acceptors on the exterior of cell. We recently characterized flavin-based system that is present in foodborne pathogen Listeria monocytogenes, as well many other Gram-positive bacteria, and which highlights more generalized role for microbial metabolism. Here we identify family putative reductases possess conserved posttranslational flavinylation modification. Phylogenetic analyses suggest divergent flavinylated reductase subfamilies distinct often unidentified substrate specificities. show member fumarate subfamily allows this enzyme receive electrons from support L. monocytogenes growth. demonstrate represents generalizable mechanism by finding strain engineered express urocanate uses related similar effect. These studies thus an exploits modular strategy reduce substrates multifunctional view activities physiology.

Published: March 17, 2021

Abstract Long-distance extracellular electron transfer has been observed in Gram-negative bacteria and plays roles both natural engineering processes. The can be mediated by conductive protein appendages (in short unicellular such as Geobacter species) or cell envelopes filamentous multicellular cable bacteria). Here we show that Lysinibacillus varians GY32, a Gram-positive bacterium, is capable of bidirectional transfer. In microbial fuel cells, L. form centimetre-range cellular networks and, when grown on graphite electrodes, the cells reach remarkable length 1.08 mm. Atomic force microscopy microelectrode analyses suggest conductivity linked to pili-like appendages. Our results long-distance not limited bacteria.
