Summary: Important efforts have been made to improve drug acts, leading to the discovery of novel drug preparations and delivery systems. Selection of green solvents for drug discovery and delivery depends on understanding the interaction between drug molecules and solvents. Deep eutectic solvents (DESs) are used in sustainable extraction methods for their high solvent power, stability, non-toxicity, and non-flammability. This research focuses on the solubility of hesperidin in water and DES solvents, and the estimation of Hansen solubility parameters for analyzing dissolution processes.

Summary: Fast and accurate estimation of the lipophilicity of organofluorine molecules is in high demand. An efficient model called PoLogP is developed to predict the lipophilicity of these molecules based on the combination of polarity descriptors and hydrogen bond index. The model utilizes a multilevel attention graph convolutional neural network to generate polarity descriptors quickly. Experimental results demonstrate that PoLogP outperforms the dipole moment method in predicting the lipophilicity of organofluorine molecules.

Summary: Atmospheric organic aerosol particles have significant impacts on climate, human health, and environmental health. Secondary organic aerosol (SOA), formed by the gas-to-particle partitioning of oxidized volatile organic compounds (VOCs), contributes a large fraction of the organic material in aerosols. This study investigated the accretion reactions of compounds containing reactive hydroperoxide, hydroxyl, carboxyl, aldehyde, and ketone groups in organic/aqueous mixtures. The reactions and products were characterized, and the rate and equilibrium constants were determined. These findings provide valuable insights into the formation of atmospheric aerosols and can improve the modeling of SOA chemistry.

Summary: A demonstrator plant for an improved sludge degradation process has been implemented on a municipal scale. By introducing an aerobic sewage sludge reactivation stage, the biogas yield increased by 55% and the remaining fermentation residue volume reduced by 25%. NH4-N removal of over 90% was achieved, and the reactivated digestate showed a reduced number of methane-forming archaea and presence of ammonium-oxidizing bacteria.

Summary: This study investigated the performance of a laboratory scale completely mixed aerobic reactor for the treatment of starch wastewater. The reactor operated for 119 days with 5 operational phases, including start-up and variation of cell-residence time. The biokinetic coefficients for starch removal were determined by varying the cell-residence time and maintaining a hydraulic retention time of 24 hours. The results showed that the coefficients were within the range of those reported for conventional activated sludge processes.

Summary: The main issues and characteristics of aerobic biological wastewater treatment in oil refineries are analyzed, with a recommendation for biosorption method intensification. Laboratory studies show that introducing waste products as alternative sorbents can be effective, especially during the receipt of highly contaminated wastewater. The efficiency of biological purification can be significantly increased with the addition of adsorbents, maintaining the species diversity of activated sludge and stability of the treatment system.

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: Water for injection (WFI) production in the biopharmaceutical industry consumes excessive amounts of water and energy. Recycling buffers can potentially save up to 90% of resources, but achieving the full theoretical potential is impossible when a risk-aware design is used. Universal risk-based assessment is important for regulatory authorities to consider the implementation of such a strategy.

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.

Summary: The utilization of biochar-immobilized microorganisms is an effective method for eliminating phenol from water. The high susceptibility of bacteria to environmental factors is a challenge for practical implementation. In this study, biochar was used to reduce microbial susceptibility and enhance phenol removal. The addition of biochar altered the dominant species of phenol-degrading bacteria and response surface analysis indicated the significant influence of biochar pyrolysis temperature and experimental temperature on phenol removal rate.

Summary: This study investigated the effect of Fenton pre-treatment on the treatment efficiency of printing and dyeing wastewater (PDW) using two anaerobic/aerobic-membrane bioreactors (A/O-MBRs). The results showed that Fenton pre-treatment significantly improved the removal efficiency of COD and AOX in PDW, and reduced membrane fouling. The Shannon indices and metagenomics analysis indicated that the microbial diversity in anaerobic flocs was higher than that in aerobic flocs, and EC3.1.1.45 and pcaI were identified as key functional genes.
