Summary: This study investigated the use of sewage sludge and cattail litter as raw materials to prepare biochar, which was then used as filling materials in constructed wetlands (CWs) to enhance the treatment of secondary effluent. The results showed that the biochar-filled CWs had better removal efficiency for total nitrogen and phosphorus compared to the control group. The biochar also reduced nitrous oxide emissions and promoted the activities of key enzymes involved in pollutant removal. High-throughput sequencing revealed the enrichment of microorganisms related to nitrogen removal in the biochar-filled CWs. This research demonstrates the potential for energy-saving treatment and waste resource recovery in wastewater treatment plants.

Summary: This study found that constructed wetlands integrated with the bioelectrochemical system can effectively degrade bio-refractory compounds and improve nitrogen removal efficiency. Low concentrations of p-Chloronitrobenzene inhibit ammonia oxidation in wetlands, while high concentrations of p-Chloronitrobenzene have a significant impact on microbial biomass in wetlands. The introduction of the bioelectrochemical system can increase microbial biomass and functional gene abundance in wetlands, enhancing their stability.

Summary: This study presents a novel approach combining phytoremediation and bio-electrochemical technology to remove Cr(VI) from wastewater using an Acorus calamus L. constructed wetland microbial fuel cell (CW-MFC). The planted CW-MFC showed high efficiency in removing Cr(VI), and the power generation was improved with the addition of low concentrations of Cr(VI). The main removal pathways of Cr involved bio-electrochemical reduction and plant uptake. This research provides valuable insights for the practical application of CW-MFC in Cr(VI)-containing wastewater treatment.

Summary: This study compares the environmental and economic performance of a conventionally constructed wetland (CW) and an integrated bioelectrochemical-constructed wetland system (ECW) using the life cycle assessment method. The results show that although ECW has a higher environmental impact from construction materials, it overall has a lower environmental impact and mitigates global warming potential compared to CW. In terms of cost, ECW can reduce total costs by 61.8% while reaching the same effluent standard as CW, making it environmentally and economically feasible.

Summary: This study investigated the effect of biochar on domestic wastewater treatment by constructed wetlands. The results showed that adding biochar as a substrate and electron transfer medium improved nitrogen removal through nitrification, denitrification, and electron transfer processes. The presence of biochar increased nitrate generation in the substrate but decreased it in the electron transfer treatment. Biochar also significantly increased the abundance of nitrifying and denitrifying genes, as well as the presence of Geobacter, a bacteria related to electron transfer. These findings suggest that biochar could enhance nitrogen removal in constructed wetlands.

Summary: This study proposes normalized maximum detection range (NMDR) and normalized sensing time (NST) as criteria for evaluating the performance of bioelectrochemical system (BES) based biosensors for organic sensing. The study focuses on constructed wetland-microbial fuel cell (CW-MFC) and suggests considering normalized toxicity (NT) as an evaluation factor. Chemical disturbances have insignificant impact on the electrical signals generated from the CW-MFC system, showing potential for monitoring NO3- in effluents or groundwater.

Summary: In response to the growing social demand for sustainable developments, biomass is increasingly being recognized as valuable feedstocks for the chemical industry. Metabolic engineering and genome editing techniques have enabled microbial fermentation to produce value-added chemicals from biomass, with the aim of improving diversity and efficiency. However, existing fermentation technologies face limitations in terms of balancing redox equivalents between substrates and products, resulting in limited variety. One potential solution to this limitation is electro-fermentation (EF), which utilizes bioelectrochemical systems to modify the intracellular redox state of electrochemically active bacteria, overcoming the redox constraint. While recent studies have explored the concept of EF for chemical production, its practical application and production efficiency still need further demonstration.

Summary: Antimicrobial resistance (AMR) is a major global health threat, and current surveillance programs lack monitoring outside healthcare settings. Wastewater testing can provide a simple and continuous way to survey AMR trends in the community. By monitoring wastewater in Greater Sydney, Australia, we found regular presence of extended-spectrum beta-lactamases-producing Enterobacteriaceae (ESBL-E), and occasional presence of carbapenem-resistant Enterobacteriaceae (CRE), vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA). Our study highlights the potential of routine wastewater surveillance for understanding factors driving AMR distribution.

Summary: The excessive usage of non-renewable resources to produce plastic commodities has significantly impacted the environment. Bioplastics derived from renewable energy have been explored as an alternative to conventional plastics. However, the efficient production of microbial bioplastics faces challenges in process optimization. Computational tools such as genome-scale metabolic modeling have been used to understand the effect of genomic and environmental perturbations on microorganism behavior. Techno-economic analysis and life cycle assessment are also important for large-scale production of microbial bioplastics. This review focuses on the efficacy of these computational techniques in optimizing the production of microbial polyhydroxy alkanoates (PHA) as a replacement for fossil-based plastic products.

Summary: Applications of advanced oxidation processes (AOPs) in water and wastewater treatment have been of great interest. UV-chlorine (UV-Cl) is emerging as a potentially cost-effective alternative to UV/hydrogen peroxide (UV-H2O2), showing efficient degradation of emerging chemicals in contaminated water. UV-H2O2 does not have superiority over UV-Cl in terms of disinfection by-product (DBP) formation. However, more investigation and pilot-scale studies are needed to establish UV-Cl as a reliable alternative to UV-H2O2.
