The electrically conductive, nanowire-like structures that connected the syntrophic propionate degrader, P. thermopropionicum, with its methanogenic partner (Gorby et al., 2006) have subsequently been shown to be flagella (Shimoyama et al., 2009). So far

1. Introduction

Subsequent studies have demonstrated electrically conductive pili and the outer membrane c-type cytochrome OmcS, as the route of extracellular electron flow between the microbes and the iron oxides. Electrically conductive pili known as microbial nanowires, are one of the most surprising discoveries in Electromicrobiology.

Direct Exchange of Electrons Within Aggregates of an

2010/12/3Syntrophic bacteria live on the metabolic by-products of a partner species. The exchange of the by-products accompanies a flow of electrons in the opposite direction that helps some species grow in conditions that would otherwise be unfavorable. In mixed anaerobic cultures of two related Geobacter species, Summers et al. (p. [1413][1]) observed that one species evolved to promote the transfer

Comparison of four technical lignins as a resource for electrically conductive carbon particles, BioRes. 14(1), 1091-1109. Abstract Carbon microparticles were produced from different technical lignins, i.e., kraft lignin, soda lignin, lignosulfonate, and organosolv lignin, at different carbonisation temperatures (800 C, 1200 C, 1600 C, and 2000 C).

What Makes Metals Conductive?

2020/3/2This is the case in the most conductive metals, such as silver, gold, and copper. Each has a single valence electron that moves with little resistance and causes a strong repelling reaction. Semiconductor metals (or metalloids ) have a higher number of valence electrons (usually four or more).
