Microbial electrochemical systems are a highly versatile platform technology with particular focus on the interplay of chemical and electrical energy conversion offer immense potential for sustainable bioeconomy. The industrial realization this requires critical biofilm optimization if performance is to be controlled over long period time. Moreover, aspect influence cooperativity has addressed as many applied anodic bioelectrochemical will most likely operated diversity interacting microbial...
The use of living microorganisms integrated within electrochemical devices is an expanding field research, with applications in microbial fuel cells, biosensors or bioreactors. We describe the porous nanocomposite materials prepared by DNA polymerization carbon nanotubes (CNTs) and silica nanoparticles (SiNPs) for construction a programmable biohybrid system containing exoelectrogenic bacterium Shewanella oneidensis. initially demonstrate electrical conductivity CNT-containing composite...
Wastewater treatment using aerobic granular sludge has gained increasing interest due to its advantages compared conventional activated sludge. The technology allows simultaneous removal of organic carbon, nitrogen, and phosphorus in a single reactor system is independent space-intensive settling tanks. However, the microscale, an analysis processes microbial population along radius granules challenging. Here, we introduce model for on small scale by machine-assisted microfluidic cultivation...
Abstract Biofilm formation by Shewanella oneidensis has been extensively studied under oxic conditions; however, relatively little is known about biofilm anoxic conditions and how architecture composition can positively influence current generation in bioelectrochemical systems. In this study, we utilized a recently developed microfluidic analysis setup with automated 3D imaging to investigate the effects of extracellular electron acceptors synthetic modifications polymeric matrix on...
The isolation of Bradyrhizobium strain I71 expands the distribution acetylene-consuming microbes to include a group economically important microorganisms. Members are well studied for their abilities improve plant health and increase crop yields by providing bioavailable nitrogen.
In bioelectrochemical systems (BES), biofilm formation and architecture are of crucial importance, especially for flow-through applications. The interface between electroactive microorganisms the electrode surface plays an important often limiting role. To overcome limitation available surface, nanoparticles (NPs) with a magnetic iron core conductive, hydrophobic carbon shell were used as building blocks to form micropillars on anode surface. this dynamic three-dimensional was monitored...
Acetylene (C 2 H ) is a trace constituent of Earth’s modern atmosphere and used by acetylenotrophic microorganisms as their sole carbon energy source (Akob et al. 2018) Acetylenotrophs hydrate acetylene through reaction catalyzed hydratase, which heterogeneous class enzymes. As 2018, there were 15 known strains acetylenotrophs including aerobic species affiliated with the Actinobacteria, Firmicutes anaerobic Desulfobacterota. However, we hypothesized that was an unknown diversity in nature....
