Summary of "Stay connected: Electrical conductivity of microbial aggregates."

The discovery of direct extracellular electron transfer offers an alternative to the traditional understanding of diffusional electron exchange via small molecules. The establishment of electronic connections between electron donors and acceptors in microbial communities is critical to electron transfer via electrical currents. These connections are facilitated through conductivity associated with various microbial aggregates. However, examination of conductivity in microbial samples is still in its relative infancy and conceptual models in terms of conductive mechanisms are still being developed and debated. The present review summarizes the fundamental understanding of electrical conductivity in microbial aggregates (e.g. biofilms, granules, consortia, and multicellular filaments) highlighting recent findings and key discoveries. A greater understanding of electrical conductivity in microbial aggregates could facilitate the survey for additional microbial communities that rely on direct extracellular electron transfer for survival, inform rational design towards the aggregates-based production of bioenergy/bioproducts, and inspire the construction of new synthetic conductive polymers.

Medical and Biotech [MESH] Definitions

Materials that have a limited and usually variable electrical conductivity. They are particularly useful for the production of solid-state electronic devices.

Determination of the quantity of a material present in a mixture by measurement of its effect on the electrical conductivity of the mixture. (Webster, 3d ed)

Naturally-occurring or artificially made water-soluble POLYMERS whose repeating units are ionizable. Polyelectrolytes demonstrate attributes that are typical of salts, such as electrical conductivity, and typical of polymers, such as viscosity.

A genus of anoxygenic, photosynthetic, nonmotile, spherical to slightly ovoid bacterial cells occurring singly, or in aggregates of two or four, and usually surrounded with slime. It is found in stagnant water, mud of ponds, estuaries, and microbial mats of salt marshes. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
