The colonization process of the infant gut microbiome has been called chaotic, but this view could reflect insufficient documentation factors affecting microbiome. We performed a 2.5-y case study assembly human microbiome, to relate life events composition and function. Sixty fecal samples were collected from healthy along with diary diet health status. Analysis >300,000 16S rRNA genes indicated that phylogenetic diversity increased gradually over time changes in community conformed...
The upflow microbial fuel cell (UMFC) was developed to generate electricity while simultaneously treating wastewater. During a five-month period of feeding sucrose solution as the electron donor, UMFC continuously generated with maximum power density 170 mW/m2. To achieve this density, artificial electron-mediator hexacyanoferrate required in cathode chamber. increased increasing chemical oxygen demand (COD) loading rates up 2.0 g COD/L/day after which no further increases were observed,...
Anaerobic digestion is the most successful bioenergy technology worldwide with, at its core, undefined microbial communities that have poorly understood dynamics. Here, we investigated relationships of bacterial community structure (>400,000 16S rRNA gene sequences for 112 samples) with function (i.e., bioreactor performance) and environment operating conditions) in a yearlong monthly time series nine full-scale facilities treating brewery wastewater (>20,000 measurements). Each had...
Abstract This review addresses the development and experimental progress of biocathodes in microbial fuel cells (MFCs). Conventional MFCs consist biological anodes abiotic cathodes. The cathode usually requires a catalyst or an electron mediator to achieve high transfer, increasing cost lowering operational sustainability. Such disadvantages can be overcome by biocathodes, which use microorganisms assist cathodic reactions. Biocathodes are feasible potentiostat‐poised half cells, but only...
Abstract Surface functional groups constitute major electroactive components in pyrogenic carbon. However, the electrochemical properties of carbon matrices and kinetic preference or for electron transfer remain unknown. Here we show that environmentally relevant with average H/C O/C ratios less than 0.35 0.09 can directly electrons more three times faster charging discharging cycles surface have a 1.5 V potential range biogeochemical reactions invoke processes. contribute to overall flux...
An upflow microbial fuel cell (UMFC) system with a U-shaped cathode inside the anode chamber was developed and produced maximum volumetric power of 29.2 W/m3 at loading rate 3.40 kg COD/(m3 day) an operating temperature 35 °C while feeding sucrose continuously. The Coulombic efficiency decreased from 51.0% to 10.6% increase in 0.57 4.29 day). In addition, lab-scale UMFC maintained soluble chemical oxygen demand (COD) removal efficiencies exceeding 90% volatile fatty acid concentrations ∼40...
This paper provides a scaffold for the development of clear and consistent terminology classification microbial electrochemistry electrochemical technologies.
Ethanol distillation in the biofuel industry is energetically expensive because ethanol completely miscible water. Upgrading into a hydrophobic chemical that easier to separate would circumvent current fossil-fuel consumption for distillation. Here, we shaped reactor microbiome sequentially elongate carboxylic acids with 2-carbon units from dilute yeast-fermentation beer. Our continuous bioprocess produced n-caproic acid, 6-carbon-chain acid more valuable than ethanol. No antimicrobials...
Abstract We determined the effect of different mixing intensities on performance, methanogenic population dynamics, and juxtaposition syntrophic microbes in anaerobic digesters treating cow manure from a dairy farm. Computer automated radioactive particle tracking conjunction with computational fluid dynamics was performed to quantify shear levels locally. Four continuously stirred were operated at 1,500, 500, 250, 50 revolutions per min (RPM) over 260‐day period temperature 34 ± 1°C. Animal...
Multifunctional reactor microbiomes can elongate short-chain carboxylic acids (SCCAs) to medium-chain (MCCAs), such as n-caproic acid. However, it is unclear whether this microbiome biotechnology platform stable enough during long operating periods consistently produce MCCAs. During a period of 550 days, we improved the conditions an anaerobic bioreactor for conversion complex yeast-fermentation beer from corn kernel-to-ethanol industry into primarily We incorporated and in-line, membrane...
