Mutualistic interactions in planktonic microbial communities have been extensively studied. However, our understanding on mutualistic communities consisting of co-existing planktonic cells and biofilms is limited. Here, we report a planktonic cells-biofilm mutualistic system established by the fermentative bacterium Escherichia coli and the dissimilatory metal-reducing bacterium Shewanella onei...

NAD-dependent alcohol dehydrogenase (ADH) enzymes for ethanol oxidation were investigated by differential electrochemical mass spectrometry (DEMS). The broad mass spectra obtained under bioelectrochemical control and with unprecedented accuracy were used to provide new insight into the enzyme kinetics and mechanisms.

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, mechanistic understanding of extracellular electron transfer by phototrophs remains minimal. Here we describe a mediatorless bioelectrochemical ...

Bioelectrochemical systems (BES) are groups of bioelectrochemical technologies and platforms that could facilitate versatile environmental and biological applications. The performance of BES is mainly determined by the key process of electron transfer at the bacteria and electrode interface, which is known as extracellular electron transfer (EET). Thus, developing novel electrodes to encourage ...

Abstract Bioelectrochemical systems (BESs) are a new and emerging technology in the field of fermentation technology. Electrical energy was provided externally to microbial electrolysis cells (MECs) generate hydrogen or value-added chemicals, including caustic, formic acid, acetic peroxide. Also, BES designed recover nutrients, metals remove recalcitrant compounds. The variety naturally existin...

Nitrogen pollution in wastewater has been considered a worldwide risk to ecosystems. Bioelectrochemical technologies have developed recently remove nitrogen. In addition nitrogen, microplastics, as emergency pollutants wastewater, could potentially affect nitrogen removal efficiency due their toxic effects on the activity of microorganisms. This study explored how microplastics would influence ...
