Summary: The addition of zero-valent iron nanoparticles (nZVI) had different effects on methane production during anaerobic digestion of pig slurry under mesophilic and thermophilic conditions. Batch experiments showed inhibition of methane production at all tested dosages in mesophilic conditions, while boosting methane production at the lowest dosage in thermophilic conditions. Continuous operation with nZVI addition resulted in increased methane content in biogas, with a significant increase in methane production rate compared to the control in both temperature ranges. The oxidation state of nZVI exhibited immediate oxidation upon contact with substrate and gradual oxidation during reactor operation.

Summary: The increase in recirculation batches can improve the yield of biogas slurry and methane in the digestion process of community solid waste, and reduce the accumulation of volatile fatty acids. The digestion process mainly produces methane through hydrogenotrophic methanogenesis and syntrophic acetic acid-oxidizing methanogenesis. The genera Methanobacterium and Methanomassiliicoccus are closely associated with the biogas production performance.

Summary: The lignin content of feedstock was found to be the main factor affecting the biomass recalcitrance based on the anaerobic digestion analysis of 16 plant wastes from South China. To improve the anaerobic digestion performance of mixed fruit shell, hydrothermal pretreatment based on biogas slurry recycling (HPBSR) was proposed, which reduced the lignin content of mixed fruit shell and increased methane yield. The HPBSR experimental group showed no production of anaerobic digestion inhibitors and had a higher humic acid concentration, contributing to the improvement of methane yield. The results provide insights into the resource utilization of biogas slurry.

Summary: The application of mathematical models as tools and early warning indicators can optimize the anaerobic digestion process in biogas reactors. The Bioconversion Model (BioModel) was evaluated in this study for simulating common perturbation cases caused by fatty acids and ammonia inhibition. The simulations showed good agreement with experimental data on methane productivity and pH, but discrepancies were observed in the prediction of volatile fatty acids' concentrations. Adjustments to the model's kinetic parameters were necessary to improve the prediction accuracy. Overall, the BioModel demonstrated effectiveness in simulating different co-digestion strategies with fatty acid or ammonia presence.

Summary: Three inhibitors, including sodium ionophore III (ETH2120), carbon monoxide (CO), and sodium 2bromoethanesulfonate (BES), were assessed for their impact on CO2 biomethanation in microorganisms from Archaea and Bacteria domains. The study demonstrates that ETH2120 and CO can promote methane production while BES does not, indicating the inactivation of archaea. Methylotrophic methanogenesis from methylamines was the main pathway for methane production, and a slight decrease in acetate production with an increase in CH4 production was observed with the addition of 20 kPa of CO. It should be noted that all compounds had effects on the microbial community composition, although the specific effects on CO2 biomethanation were challenging to observe due to the complexity of the environmental samples used as inoculum.

Summary: Microbial fermentation combined with inexpensive biomass, such as Saccharina latissima hydrolysate, candy-factory waste, and digestate from full-scale biogas plant, can be used as an alternative to petroleum-based materials for lactic acid production. Lactic acid bacteria, including Enterococcus faecium, Lactobacillus plantarum, and Pediococcus pentosaceus, were able to utilize sugars released from seaweed hydrolysate and candy-waste. Seaweed hydrolysate and digestate also provided nutrients for microbial fermentation. A scaled-up co-fermentation of candy-waste and digestate resulted in a lactic acid concentration of 65.65 g/L and a productivity of 1.37 g/L/hour, demonstrating the successful production of lactic acid from low-cost industrial residues.

Summary: Packing materials play a significant role in improving the efficiency of biological methanation in Trickle Bed Reactors. This study evaluated the performance of pelletized activated carbon and Raschig rings as packing materials. Activated carbon outperformed Raschig rings by achieving higher methane purity, maintaining stable pH levels, and reducing gas retention time. The study also found that the digestate from biogas plants served as a sufficient nutrient source. The composition of the microbial community and the physical properties of packing materials contributed to maximizing the efficiency of biological methanation.

Summary: Wastewater from the potato processing industry, protamylasse, can be valorized through the cultivation of microalgae by mixotrophic metabolism. A new two-stage system was developed, where volatile fatty acids (VFA) were produced through anaerobic acidification (AA), and Chlorella sorokiniana was cultivated for valorization of nutrients and organics. This process resulted in high removal efficiencies of phosphorus, nitrate, and ammonia, and the production of microalgal biomass with high protein content.

Summary: This study examined the effect of trace metals on H2/CO2 biomethanation, finding that they are crucial for efficient methane production. During nutrient deprivation, the suppression of hydrogenotrophic archaea at higher gas rates led to a decrease in methane content and an increase in acetic acid concentration. After nutrient supplementation, increased concentrations of Co, Ni, and Fe were found to enhance methanogenic activity, resulting in high methane content and low acetic acid concentration. Mathematical modeling demonstrated that iron limitation suppressed hydrogenotrophic archaea, leading to hydrogen accumulation and the growth of homoacetogenic bacteria.

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.

Summary: In this study, heterologous expression and homologous overexpression of ABC transporter proteins AatA and MdlB were found to improve butyric acid production in C. tyrobutyricum. The overexpression of these proteins upregulated the expression levels of key enzymes in the acetate synthesis pathway and promoted the synthesis and secretion of acetic acid. Additionally, the increase in ATPase activity facilitated sugar utilization, induced extracellular secretion of acetate, and shortened fermentation periods.
