Biohydrogen production via dark fermentation (DF) and microbial electrolysis cells (MEC) demonstrate great potential for sustainable hydrogen generation. In this study, DF and MEC were coupled as a hybrid reactor and evaluated using brewery wastewater. The effect of hydraulic retention time (HRT) and buffer concentration on reactor performance were assessed...
A combination of batch fermentations and genome scale flux balance analysis were used to identify and quantify the rate limiting reactions in the xylulose transport and utilization pathway. Xylulose phosphorylation by xylulokinase was identified as limiting in wild type Saccharomyces cerevisiae, but transport became limiting when xylulokinase was upregulated. Further...

Poly-3-hydroxybutyrate (PHB) is a renewable, biodegradable biopolymer that has
shown great promise to offset the use of hydrocarbon-derived plastics. The genes
encoding the bacterial PHB production pathway have been engineered into several
higher order plant species providing an opportunity to produce PHB as a
co-product on an industrial, agricultural scale....

Bioethanol produced from the lignocellulosic feedstock is a potential alternative to fossil fuels in transportation sector and can help in reducing environmental burdens. Straw produced from perennial ryegrass (PR) and wheat is a non-food, cellulosic biomass resource available in abundance in the Pacific Northwest U.S. The aim of this study...
Algae have shown great potential as a source for renewable fuels. However, current production schemes have not been able to prove a sustainable energy return on investment due in part to the high costs of nutrient addition and the energy required for drying the biomass. Integrated algae-dairy production systems have...
This Jupyter Notebook is intended to accompany the publication "Agrivoltaics align with Green New Deal goals while supporting investment in the US’ rural economy".This reduced-order economic analysis estimates the total construction, operation, and energy storage costs of wide scale implementation of Agrivoltaic Systems in the United States. Additionally, estimates are...
Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...
Due to significant lipid and carbohydrate production as well as other useful properties such as high production of useful biomolecular substrates (e.g., lipids) and the ability to grow using non-potable water sources, algae are being explored as a potential high-yield feedstock for biofuels production. In both natural and engineered systems,...
