Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.

Summary: Optimal denitrification was achieved at a ratio of 2:1 by adjusting the elemental sulfur content in the composite fillers, leading to an increase in microbial abundance. The biofilm composition transitioned from a single dominant species to multiple species, with an increase in genes related to sulfur metabolism.

Summary: This study demonstrated the efficiency of bioaugmentation-phytoremediation using Typha angustifolia in removing PCP from wastewater. Significant PCP removal by indigenous bacteria and a decrease in chloride content were observed, along with an increase in bacterial numbers. Novel methods and analyses were employed to evaluate the phytoremediation process, showing positive effects on intrinsic microorganisms and promoting pollutant remediation.

Summary: The study aims to synthesize magnetically separable highly active porous immobilized laccase for the removal of PCP. Magnetic porous CLEAs (Mp-CLEAs) of laccase were synthesized and showed a 2-fold higher biocatalytic efficiency compared to magnetic CLEAs. The Mp-CLEAs exhibited mechanical stability, enhanced catalytic efficiency, and reusability, overcoming mass transfer limitations and enzyme loss. Furthermore, a laccase-surfactant-mediator system was harnessed to enhance PCP removal, achieving high removal rates.

Summary: In this study, the thiosulfate-driven denitrification and Anammox process (TDDA) was successfully started and operated continuously for 146 days, achieving good nitrogen removal efficiency. The study also revealed the positive role of the Sulfammox process in nitrogen and sulfur removal, and identified the bacteria associated with this process through high-throughput analysis.

Summary: Biological stability of digestate was evaluated using a new indicator called biological denitrification potential (BDP) in this study. Results showed that BDP values correlated well with digestion time and total organic carbon content. Furthermore, BDP was found to depend on the carbon source and denitrification activity in the digestate.

Summary: Sulforaphane (SFN) reduces ATP production in bladder cancer cells by inhibiting glycolysis and mitochondrial oxidative phosphorylation. SFN weakens glycolytic flux by suppressing metabolic enzymes such as hexokinase 2 (HK2) and pyruvate dehydrogenase (PDH). Additionally, SFN downregulates the unique glucose transport aberrant-independent aerobic glycolysis in bladder cancer through the AKT1/HK2 axis and PDH expression.

Summary: This study examined PBDD/Fs and PCDD/Fs in sediments from the Pearl River Delta, China, and found that PBDD/Fs were ubiquitous but at lower concentrations compared to PCDD/Fs. The presence of PBDD/Fs was positively correlated with local development levels, while PCDD/Fs were associated with grain planting, yield, and pesticide consumption. The study also revealed that industrial and municipal activities have been increasing their contributions to PCDD/F levels in the area, despite strict emission standards. Over sixty percent of the samples exceeded the low-risk threshold for mammalian life, indicating the need for continuous attention.

Summary: The study reveals that sedimentary denitrification is the main nitrogen removal pathway in estuarine environments, with a minor contribution from anammox. Estuarine sediments play a relatively weak role in eliminating nitrogen input, while the excess nitrogen from rivers will eventually be removed through various biological processes.
