Bioelectricity (electromicrobiology) and sustainability [PDF]

Microbial Biotechnology, 2017
Summary Electromicrobiology is the domain of those prokaryotes able to interact with charged electrodes, using them as electron donors and/or electron acceptors. This is performed via a process called extracellular electron transport, in which outer membrane cytochromes are used to oxidize and/or reduce otherwise ...

Halobacterium salinarum NRC‐1 Sustains Voltage Production in a Dual‐Chambered Closed Microbial Fuel Cell

The Scientific World Journal, Volume 2022, Issue 1, 2022., 2022
Sustained bioenergy production from organisms that thrive in high salinity, low oxygen, and low nutrition levels is useful in monitoring hypersaline polluted environments. Microbial fuel cell (MFC) studies utilizing single species halophiles under salt concentrations higher than 1 M and as a closed microbial system are limited.

Cable bacteria at oxygen‐releasing roots of aquatic plants: a widespread and diverse plant–microbe association

New Phytologist, Volume 232, Issue 5, Page 2138-2151, December 2021., 2021
Summary Cable bacteria are sulfide‐oxidising, filamentous bacteria that reduce toxic sulfide levels, suppress methane emissions and drive nutrient and carbon cycling in sediments. Recently, cable bacteria have been found associated with roots of aquatic plants and rice (Oryza sativa).

A Bioelectrochemical Approach to Characterize Extracellular Electron Transfer by Synechocystis sp. PCC6803 [PDF]

, 2014
Biophotovoltaic devices employ photosynthetic organisms at the anode of a microbial fuel cell to generate electrical power. Although a range of cyanobacteria and algae have been shown to generate photocurrent in devices of a multitude of architectures ...

Effect of salinity on cable bacteria species composition and diversity

Environmental Microbiology, Volume 23, Issue 5, Page 2605-2616, May 2021., 2021
Summary Cable bacteria (CB) are Desulfobulbaceae that couple sulphide oxidation to oxygen reduction over centimetre distances by mediating electric currents. Recently, it was suggested that the CB clade is composed of two genera, Ca. Electronema and Ca. Electrothrix, with distinct freshwater and marine habitats respectively. However, only a few studies

The bacterial antitoxin HipB establishes a ternary complex with operator DNA and phosphorylated toxin HipA to regulate bacterial persistence [PDF]

, 2014
Nearly all bacteria exhibit a type of phenotypic growth described as persistence that is thought to underlie antibiotic tolerance and recalcitrant chronic infections.

Multi-heme Cytochromes in Shewanella oneidensis MR-1:Structures, functions and opportunities [PDF]

, 2015
Multi-heme cytochromes are employed by a range of microorganisms to transport electrons over distances of up to tens of nanometers. Perhaps the most spectacular utilization of these proteins is in the reduction of extracellular solid substrates ...
