Summary: This study investigated the effect of In-Situ Chemical Oxidation (ISCO) using peroxydisulfate (PDS) on a chloroethenes-degrading microbial consortium in the presence of perchloroethene (PCE). The results showed that coupling PDS with microbial consortium did not improve PCE removal efficiency and indigenous microbes may reduce the efficiency of PDS during a remediation process. High-throughput 16S rRNA gene sequencing analysis revealed a negative impact of PDS on organohalide-respiring bacteria (OHRB).

Summary: This study selects Typha angustifolia and Juncus effuses as suitable plant species for phytoremediation of micropollutants (MPs). These two plant species were chosen due to their good ability to remove MPs, tolerate low temperatures, and resist the toxicity of MPs. The results of this study can also be applied to constructed wetlands for the removal of MPs from wastewater. Additionally, this study provides a detailed understanding of the uptake and degradation processes of the persistent MP propranolol in plants, which is significant for both the application of phytoremediation in MP removal and the development of constructed wetland studies.

Summary: There is a need for standardized in vitro models of the human intestinal tract to study intestinal health without using animals. The Caco-2 cell line is a widely accepted and characterized model for studying intestinal drug transport, host-microbe interactions, and toxicity. We investigated the effect of different experimental variables on gene expression using transcriptome analysis of Caco-2 cells grown on permeable membranes. Our analysis revealed a weak association between experimental variables and gene expression, possibly due to heterogeneity in cell culture practice and inadequate reporting. This highlights the need for improved reporting protocols and serves as a template for future comparative studies.

Summary: Optimizing bioreactor performance is crucial for sustainable and energy-efficient removal of micropollutants in tertiary treatment. The resident microbial community plays a significant role in bioreactor performance, hence a deeper understanding of community dynamics is essential. By characterizing the microbial communities in three different bioreactors used for organic matter removal, an interdependency between bioreactor performance and microbial community profile was observed. A generalized Lotka-Volterra model was established to understand the interactions in the microbial community and develop strategies for improving bioreactor performance.

Summary: Groundwater in The Netherlands is the main source of drinking water, but pesticide presence threatens its quality. Biodegradation is a natural process that can help remove pesticides. However, the oligotrophic groundwater conditions may limit biodegradation due to the lack of microbial communities capable of degrading pesticides. In this study, bioaugmentation with enriched mixed inocula was used to enhance pesticide biodegradation, and the effect of different redox conditions on biodegradation was observed.

Summary: Microalgae-based technologies can effectively remove organic micropollutants (OMPs) from wastewater, but the impact of wastewater characteristics on the removal is not well understood. This study evaluated the removal of sixteen OMPs by Chlorella sorokiniana cultivated in three types of wastewater. The results showed that the removal efficiency varied depending on the wastewater type, with longer retention time enhancing the removal of some OMPs. Wastewater soluble COD and biomass concentration were found to be the major factors affecting OMPs removal.
