Summary: In this study, the harmfulness of reduced-Cr(III) was identified through assessment of mobility and toxicity in nature. Pine bark was used to remove Cr(VI) from aqueous solution. The reduced-Cr(III) showed low mobility and was virtually non-toxic, and helpful for plant growth. Our findings demonstrate that Cr(VI) biosorption technology using pine bark is a groundbreaking technology for Cr(VI) detoxification.

Summary: In this study, two different immobilized Cr(VI)-bioreducing bacterial consortia using novel immobilization agents have been developed for Cr(VI)-polluted groundwater remediation. The addition of carbon-based agent and emulsified polycolloid substrate successfully improved the bioreduction efficiency of Cr(VI). The developed immobilized Cr-bioreducing bacteria system can effectively clean up Cr(VI)-polluted groundwater.

Summary: The present study focuses on the isolation of a highly efficient Cr(VI)-reducing bacterial strain (CR-2) from an abandoned chromate plant in Qinghai Province, China. The strain was identified as Lysinibacillus cavernae using 16S rRNA gene sequencing. CR-2 could survive at high concentrations of Cr(VI) and effectively reduce it at optimal pH, temperature, and salinity conditions. The study further investigated the factors affecting the Cr(VI) reduction by CR-2 and the mechanism behind the reduction process.

Summary: The isolated strain Lysinibacillus HST-98 shows promising results in reducing Cr(VI) pollution, even at high concentrations. Optimal growth conditions for the strain include a pH of 8-9, a temperature of 36 degrees Celsius, and sodium lactate as an electron donor. Coexisting metal ions like Cu2+, Co2+, and Mn2+ enhance Cr(VI) reduction, while Zn2+, Ni2+, and Cd2+ have the opposite effect. The reduction mechanism of strain HST-98 is primarily mediated by intracellular enzymes, and the genes and enzymes related to chromium metabolism in this strain have been annotated to further understand its mechanism.

Summary: This study investigated the interactions between polyethylene MPs and the floating aquatic macrophyte Lemna minor. The results showed that the maximum number of adhered MPs was reached after 24 hours and increased with plant biomass. Slow water movement did not significantly affect MP adhesion. Among different adsorption models, the Freundlich adsorption isotherm model provided the best fit, suggesting weak binding of MPs to plant biomass. The study also found that 79% of MPs were removed during 15 cycles of phytoremediation, with an estimated 53 cycles needed to remove all MPs under test conditions.

Summary: The study identified arsenic-resistant bacteria PMS5 with bioaccumulation and biosorption abilities, as well as the capacity for volatilization and biotransformation of arsenic oxyanions. PMS5 significantly contributed to bioprocessing of arsenic under oligotrophic conditions and reduced biofilm density in reactors. Nonetheless, negligible arsenic volatilization was detected in the study.

Summary: Acquiring long-term time series of climate, hydrology, and hydrochemical data is crucial for understanding the complex interactions in the Critical Zone. Despite the importance of humid tropical regions in terms of population density and land use, few Critical Zone Observatories are located in these areas. Data shared by M-TROPICS in Cameroon have contributed to understanding water partitioning, chemical weathering, and erosion processes in tropical ecosystems. The fluctuating solute concentrations at the Nyong River tributary outlet highlight the need for longer time-series and ongoing support for CZOs in the humid tropics.

Summary: Mapping soil properties is becoming more challenging due to human modifications of the landscape. The traditional practice of applying tank silt to agricultural fields in South India is beneficial for soil fertility, but the extent of this practice needs further investigation. The study demonstrates the potential of using Sentinel-2 images to accurately map tank silt application and evaluate soil color changes related to this practice.

Summary: Climate change, variability, and land use change are the main drivers of river discharge variability. The decrease in rainfall is synchronous with the decrease in discharges in large basins, while it is concomitant with an increase in a small basin. Land use change has an impact on extreme discharges, with increases in impervious areas and reductions in forest cover leading to changes in discharge patterns. Precipitation in the dry season affects the flows in the following rainy seasons. The impact of precipitation on discharge varies in different seasons and time periods.

Summary: Due to climate and environmental changes, sub-Saharan Africa has been experiencing drought and flood events, impacting the economy of the region. This study specifically focuses on the So'o River Basin in Cameroon and analyzes the current and future flows using hydrometeorological time series and simulation models. The results suggest a decrease in river discharge due to a decrease in precipitation for the current period and a possible decrease in future periods, except under certain scenarios where a slight increase is projected.

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.
