Before cyanobacteria invented oxygenic photosynthesis and O 2 and H 2 O began to cycle
between respiration and photosynthesis, redox cycles between other elements were used to …

Electroactive bacteria produce or consume electrical current by moving electrons to and
from extracellular acceptors and donors. This specialized process, known as extracellular …

Transition metals are known to cause toxic effects through their interaction with oxygen, but
toxicity under anoxic conditions is poorly understood. Here we investigated the effects of iron …

Natural living conductive biofilms transport electrons between electrodes and cells, as well
as among cells fixed within the film, catalyzing an array of reactions from acetate oxidation to …

The purple bacterium Rhodopseudomonas palustris TIE-1 expresses multiple small high-potential
redox proteins during photoautotrophic growth, including two high-potential iron-…

The junction of bioelectrochemical systems and synthetic biology opens the door to many
potentially groundbreaking technologies. When developing these possibilities, choosing the …

Here, we report on the development of a genetic system for Marinobacter sp. strain CP1,
previously isolated from the Biocathode MCL community and shown to oxidize iron and grow as …

Biofilms growing aerobically on conductive substrates are often correlated with a positive,
sustained shift in their redox potential. This phenomenon has a beneficial impact on microbial …

Serpentinization is a geologic process that produces highly reduced, hydrogen‐rich fluids
that support microbial communities under high pH conditions. We investigated the activity of …

Three highly alkaliphilic bacterial strains designated as A1 T , H1 T and B1 T were isolated
from two highly alkaline springs at The Cedars, a terrestrial serpentinizing site. Cells from all …
