Summary: Gas emitted from landfills contains a large quantity of volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs), some of which are carcinogenic, teratogenic, and mutagenic. The global hazards of VOCs and SVOCs in landfill gas to human health remain unclear. To quantify the global risk distributions of these pollutants, the composition and concentration data of VOCs and SVOCs from 72 landfills in 20 countries were collected and their human health risks were assessed. Organic compounds in landfill gas primarily result from the biodegradation of natural organic waste or the emissions and volatilization of chemical products. The respiratory system, particularly the lung, was found to be the major target organ of VOCs and SVOCs, with additional adverse health impacts ranging from headache and allergies to lung cancer. Aromatic and halogenated compounds were the primary sources of health risk, while ethyl acetate and acetone from the biodegradation of natural organic waste also exceeded the acceptable levels for human health. Overall, VOCs and SVOCs affected residents within 1,000 m of landfills. Air temperature, relative humidity, air pressure, wind direction, and wind speed were the major factors that influenced the health risks of VOCs and SVOCs. Currently, landfill risk assessments of VOCs and SVOCs are primarily based on respiratory inhalation, with health risks due to other exposure routes remaining poorly elucidated. In addition, potential health risks due to the transport and transformation of landfill gas emitted into the atmosphere should be further studied.

Summary: Improper discharge of industrial effluents can lead to contamination of water, air, and soil systems. Current treatment technologies involving chemical, biological, and physical approaches have been proven effective, as well as utilizing high organic content in waste for microbial metabolism. However, clear understanding of engineering aspects and feasibility at pilot-scale level is crucial before commercialization attempts.

Summary: The main aim of this study was to optimize and maximize the impacts of biodegradation of odor and volatile organic compounds (VOCs) in a wastewater treatment plant using a compact trickle bed bioreactor (CTBB) on a pilot scale. The CTBB was tested with gases from a tank containing semi-liquid fats, oils, and fat waste and showed pollutant removal efficiency ranging from 81.5% to 99.5% for VOCs, 87.5% to 98.9% for H2S, and >99% for NH3. In the liquid phase, the removal efficiency was higher at pH = 7.0 than at pH = 5.0.

Summary: This review discusses the strategies and recent advances in using microbial consortia to degrade complex compounds, including plastics, petroleum, antibiotics, azo dyes, and pollutants in sewage. It is shown that microbial consortia have advantages over isolated bacteria as they are more adaptable and stable, and can provide a suitable catalytic environment for each enzyme. The development of synthetic biology and gene-editing tools allows the design of artificial microbial consortia systems that are more efficient, stable, and robust.

Summary: The presence of phosphorus in borosilicate and iron-phosphate glasses affects their dissolution rates. Organic carbon breakdown increases dissolution, while microbial reduction of Fe(II) slows it down and interaction of Fe(III) accelerates it. Phosphorus addition has no significant effect on microbial species, but enhances microbial community diversity.

Summary: This study investigated the effect of pre-salting duration on the fermentation of Suancai, a type of fermented vegetable. It was found that longer pre-salting duration led to a more acidic and milder flavor, as well as reduced pungent off-flavors. The microbial composition of Suancai was also influenced by pre-salting duration, with certain genera being more abundant in longer pre-salted samples.

Summary: This study investigated the early-stage response of six lab-scale biogas bioreactors fed with different amounts of a sulfaterich organic agro-industrial effluent. The results showed that the yield of hydrogen sulfide (H2S) transitioned from transient to steady state within 2 weeks for all conditions. Additionally, volatile sulfur compounds (VSCs) such as methanethiol (MeSH) and dimethyl sulfide (DMS) were generated at high sulfate loads. Changes were observed in the microbial community structures, with a higher abundance of genes involved in the dissimilatory sulfate-reduction pathway in high loaded sulfate bioreactors. Principal component analysis (PCA) and correlation analyses revealed strong relationships between H2S, VSCs, and the microbial community.

Summary: This study investigates the impact of ammonia crossover on the performance of thermally regenerative ammonia-based batteries (TRABs). It is found that the amount of ammonia crossover increases with the initial ammonia concentration, discharging current, and temperature. By regulating ammonia transfer, the ammonia diffusion layer can effectively alleviate ammonia crossover. The content of polytetrafluoroethylene (PTFE) in the gas diffusion layer significantly influences ammonia transfer to the porous anode and cathode.

Summary: Maintaining electroactive biofilms with good metabolic activity is essential for high and stable performance in bioelectrochemical systems (BESs). Proton transport plays a significant role in biofilm metabolic activity through microenvironment pH, making it crucial to investigate proton transfer properties within the biofilms to enhance BES performance. In this study, the proton transport in electroactive biofilms was explored using in situ microelectrode measurements, which innovatively measured the diffusion coefficient in live biofilms under non-destructive conditions. The non-destructive measurement of diffusion coefficients not only brings the results closer to reality, but also enriches the understanding of biochemical processes and physicochemical information. By combining with a mathematical model, it was demonstrated that the accumulation of protons in the biofilm is a key factor in inhibiting electricity generation. The efficient characterization of proton transfer within the biofilm provides realistic guidance for constructing high-performance BESs.

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.
