Surface chemistry is known to influence the formation, composition, and electroactivity of
electron-conducting biofilms. However, understanding of the evolution of microbial …

Bacteria residing within biofilm communities can coordinate their behavior through cell-to-
cell signaling. However, it remains unclear if these signals can also influence the behavior of …

It is the ambition of many researchers to finally be able to close in on the fundamental,
coupled phenomena that occur during the formation and expression of electrocatalytic …

Here we report enrichment from a marine-derived inoculum of a nonphotosynthetic
electroactive biofilm that is capable of both consuming electricity (electrotrophy) and …

Anodic electroactive biofilms (EABs) are commonly grown under continuous polarization of
the underlying electrode. Their growth under appropriate periodic polarization was recently …

The discovery of direct extracellular electron transfer offers an alternative to the traditional
understanding of diffusional electron exchange via small molecules. The establishment of …

Periodic polarization can improve the performance of anodic electroactive biofilms (EABs).
The impact of the half-period duration was previously investigated at constant duty cycle …

With applications in bioremediation, biosensing, and bioenergy, microbial electrochemical
systems are a rapidly growing, multidisciplinary field within biological, chemical, and …

Growth in three-electrode electrochemical cells allows quantitative analysis of mechanisms
involved in electron flow from dissimilatory metal reducing bacteria to insoluble electron …

Electrochemical gradients are the backbone of basic cellular functions, including chemo-
osmotic transport and ATP synthesis. Microbial growth, terminal respiratory proteins and …
