Summary: A bio-electrochemical reactor (BER) using copper wire and graphite plate was developed to purify NO3-N-contaminated groundwater. Different electric currents and water hardness levels were used to examine the total nitrogen removal efficiency and NO3-N removal mechanisms. The results showed that both heterotrophic and autohydrogenotrophic denitrification reactions occurred in the suspended sludge of the BERs. The microbial analysis revealed the presence of different dominant genera under different reaction conditions.

Summary: Excess unmanaged nitrogen pollution is detrimental to the environment. The integration of biological nitrogen removal in bio-electrochemical systems (BES) provides a green technology solution for achieving efficient and cost-effective wastewater treatment. This analysis highlights the importance of electrode materials, operational parameters, and microbial community structure in optimizing NO3 removal efficiencies in BES. Additionally, the study provides evidence of other nitrogen removal processes, such as anaerobic ammonium oxidation (ANAMMOX) and dissimilatory NO3 reduction to ammonium (DNRA), supported by electrochemical processes in BES.

Summary: Stimulating litho-autotrophic denitrification with hydrogen is a promising strategy to remove excess NO3-, but it often leads to the accumulation of cytotoxic intermediate NO2- and greenhouse gas N2O. This study investigated if the genomic composition, gene transcription regulation, or kinetics of reductases contribute to the high concentrations of NO2- and N2O. The findings suggest that the kinetics of reductases and the expression of N2O reductase play a role in the accumulation of NO2- and N2O during denitrification.

Summary: A sustainable electrochemical pathway for the degradation and thermal treatment of technical lignosulfonate is proposed. This method allows for the production of significant quantities of low molecular weight compounds, including vanillin and acetovanillone. The electrochemical degradation is carried out using a simple two-electrode setup in aqueous media, which can be easily scaled up. The biopolymer is oxidized at the anode, while hydrogen is evolved at the cathode. Subsequent thermal treatment further degrades the robust chemical structure of lignosulfonates. Under optimized electrolytic conditions, vanillin can be obtained in a yield of 9.7 wt% relative to the dry mass of lignosulfonate used. By-products such as acetovanillone or vanillic acid are also observed but in lower yields. Overall, this study establishes a new and reliable one-pot, two-step degradation process for various technically relevant lignosulfonates, offering the advantage of using electrons as an oxidizing agent and resulting in minimal reagent waste.

Summary: This study demonstrated the successful removal of high nitrate concentrations from groundwater using a novel pressurized hydrogenotrophic denitrification reactor, while preventing nitrogen gas accumulation in the reactor's headspace. By connecting the main reactor to an external degassing unit and implementing liquid recirculation, steady-state nitrogen and hydrogen gas partial pressures were maintained, achieving nitrate removal rates over 97% with denitrifying rates up to 6 g N/L-reactor/d under both freshwater and brine conditions. The dynamic conditions in the reactor system led to reduced external recirculation flow requirements and greater than expected hydrogen utilization rates of over 93%.

Summary: This study compares the performance of a nanofiber device and a resin column for antibody capture. The nanofiber device has a larger housing volume and lower binding capacity, but comparable eluate purity to the resin column. It shows high stability, can be used for multiple cycles, and maintains consistent eluate quality when scaled up. The use of a single nanofiber device can significantly reduce costs compared to a resin column, especially when the number of batches is limited.

Summary: Fed-batch cell culture processes are commonly used in biomanufacturing due to their simplicity and applicability in cGMP environments. However, the challenge lies in the changing physiochemical conditions within the bioreactor as the cell density changes. Traditional response surface models (RSMs) are commonly used for optimization but are limited by their use of time-invariant factors. Dynamic RSM (DRSM) models can predict the time-dependent impact of process inputs, allowing for optimization of process operations that change over time.
