Summary: This study investigated the production of volatile fatty acids (VFAs) and substrate consumption in anaerobic fermentation under different carbohydrate-to-protein (Car/Pro) ratios. The highest VFAs yields were observed at a Car/Pro ratio of 1 for BSA-dextran and amino acids-glucose fermentation. Hydrolysis and acidogenesis were identified as the limiting processes for higher and lower Car/Pro ratios, respectively. Accumulation of amino acids was found to have an inhibitory effect, but VFAs production could be increased by 25.5% through quartic fed-batch strategy. The activity of hydrolytic and acid-forming enzymes was significantly related to the efficiency of acidogenic metabolism.

Summary: A large amount of household food waste is produced annually, leading to environmental issues and financial burdens. Anaerobic fermentation of household food waste to produce lactic acid, a valuable platform chemical, is a promising method for resource recovery. However, the yield of lactic acid from household food waste is low. This paper compared different pretreatment methods and found that the combined pretreatment at pH 10 and 120°C significantly increased lactic acid production compared to single hydrothermal and chemical pretreatment. The pretreatment process facilitated the dissolution of organics, especially polysaccharides and amino acids, and influenced lactic acid production by Lactobacillus rhamnosus ATCC 7469. Among the amino acids, aspartic acid, threonine, glutamic acid, glycine, alanine, cystine, valine, isoleucine, arginine, and proline showed significant correlation with lactic acid concentration.

Summary: In this study, the effects of Fe3O4 on the production of volatile fatty acids (VFAs) in the anaerobic fermentation process of waste cooking oil (WCO) and aerobic sludge (AS) were investigated. The results showed that the addition of Fe3O4 promoted the hydrolysis and acidification of WCO, leading to an increase in VFAs and propionic acid concentration. Microbial community analysis revealed that Firmicutes, Proteobacteria, and Bacteroidetes were the main phylum involved in VFA production, with Veillonellaceae under Firmicutes being the main microorganism responsible for propionic acid production. This study provides new insights for the utilization of Fe3O4 in WCO treatment and propionic acid production.

Summary: Bioenergy production from lignocellulosic biomass (LCB) is an important topic for meeting energy demand, addressing climate change and waste management. Hydrothermal pretreatment is gaining popularity for organics recovery from LCB and can lead to the production of biohydrogen and biomethane. Integration approaches and utilization of solid residue obtained from LCB pretreatment were also discussed. The importance of hydrothermal pretreatment as a suitable strategy for LCB utilization and its future potential in large-scale energy recovery were emphasized.

Summary: The study aimed to investigate the effect of moisture content on microbial communities and metabolites, and found that high-moisture content improved aerobic stability while low-moisture content resulted in higher pH and lactic acid bacterial count during aerobic exposure. Acinetobacter sp. and Candida glabrata dominated the bacterial and fungal communities, with their activities negatively impacting aerobic stability in high-moisture silages. High-moisture silages contained greater total metabolites and various fatty acids and amino acids during aerobic exposure.

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.
