A seasonally operated full-scale membrane bioreactor plant (flat sheet, 0.03 μm) treating municipal wastewater from a recreation facility was monitored for 2 years. In particular, membrane bioreactor operation characteristics and development and changes in extracellular polymeric substances and soluble microbial product concentrations were observed, which were both dependent on volume and quality of incoming wastewater. Microbiological effluent quality, nutrient removal efficiency and activated sludge characteristics were analysed on a regular basis. Correlations between activated sludge quality, extracellular polymeric substance and soluble microbial product concentrations were identified. Pathogen related changes in effluent quality during plant operation were also observed. Nutrient removal efficiency was very good, despite fluctuations in influent flow.

Methicillin-resistant (MRSA) is a refractory pneumonia-causing pathogen due to the antibiotic resistance and the characteristics of persisting inside its host cell. Lysostaphin is a typical bacteriolytic enzyme for degrading bacterial cell walls via hydrolysis of pentaglycine cross-links, showing potential to combat multidrug-resistant bacteria. However, there are still grand challenges for native lysostaphin because of its poor shelf stability and limited bioavailability.

Covalent modification of cell membranes has shown promise for tumor imaging and therapy. However, existing membrane labeling techniques face challenges such as slow kinetics and poor selectivity for cancer cells, leading to off-target effects and suboptimal efficacy. Here, we present an enzyme-triggered self-immobilization labeling strategy, termed E-SIM, which enables rapid and selective labeling of tumor cell membranes with bioorthogonal trans-cycloctene (TCO) handles .

Managing wastewater and using renewable energy sources are challenges in achieving sustainable development goals. This study provides an overview of the factors influencing the performance of algae-based membrane bioreactors (AMBRs) for contaminant removal from wastewater and biogas production. This review highlights that the performance of AMBRs in removing total phosphorus (TP) and nitrogen (N) from wastewater can reach up to 93% and 97%, respectively, depending on parameters such as pH, hydraulic retention time (HRT), and algae concentration.

Mitigating the release of extracellular antimicrobial resistance genes (exARGs) from wastewater treatment plants (WWTPs) is crucial for preventing the spread of antimicrobial resistance from human domains into the environment. This study aimed to evaluate the applicability of intI1 as a performance indicator for securing the removal of exARGs at WWTPs. We investigated the reduction of exARGs and intI1 in a full-scale WWTP, where identical wastewater was treated using conventional activated sludge (CAS) and membrane bioreactor (MBR) systems.

Energy from renewable resources has been growing in popularity, which ultimately helps reduce emissions of greenhouse gases (GHGs) and contaminants. Since hydrogen (H) has a higher combustion production of energy than hydrocarbon fuels, it has been identified as a clean, sustainable, and environmentally friendly energy source. There are several benefits to producing biohydrogen (bioH) from renewable sources, including lower cost and increased sustainability.
