Severe infections caused by multi-drug-resistant Gram-negative rods pose a clinical threat due to their high mortality risk. The global spread of plasmid-mediated colistin-resistance genes has become a serious problem. In this study, we identified spp. harboring and from a wastewater treatment plant in Japan.

Previous studies have indicated the great performance of electrooxidation (EO) to mineralize per- and polyfluoroalkyl substances (PFASs) in water, but different anions presented in wastewater may affect the implementation of EO treatment in field applications. This study invetigated EO treatment of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), two representative perfluoroalkyl acids (PFAAs), using porous Magnéli phase titanium suboxide anodes in electrolyte solutions with different anions present, including NO3-, SO42-, CO32- and PO43-. The experiment results indicate that CO32- enhanced PFAS degradation, while NO3- suppressed the degradation reactions with its concentration higher than 10 mM.

Purifying methane from natural gas using adsorbents not only requires the adsorbents to possess excellent separation performance but also to overcome additional daunting challenges such as humidity interference and durability requirements for sustainable use. Herein, porous organic crystals of a new macrocycle () with superhydrophobic and self-healing features are prepared and employed for the purification of methane (>99.99% purity) from ternary methane/ethane/propane mixtures under 97% relative humidity.

Wastewater is commonly contaminated with many pharmaceutical pollutants, so an efficient purification method is required for their removal from wastewater. In this regard, an innovative tertiary Se/SnO@CMC/Fe-GA nanocomposite was synthesized through encapsulation of metal organic frameworks (Fe-glutaric acid) onto Se/SnO-embedded-sodium carboxy methyl cellulose matrix to thoroughly evaluate its effectiveness for adsorption of levofloxacin drug from wastewater. The prepared Se/SnO@CMC/Fe-GA nanocomposite was analyzed via UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) to valuate optical property, size, morphology, thermal stability, and chemical composition.

The consideration of scarcity and overexploitation of freshwater at the organizational level increased interest in the water footprint. The water footprint measures freshwater use for activities, taking into account water consumption and pollution contamination by classifying consumed water into groundwater and surface water (blue water), rainwater (green water), and polluted water (grey water). This study aims to identify a comprehensive water footprint inventory analysis for a denim washing organization and assess the grey water footprint (GWF) based on the effluent concentration of pollution indicators (chemical oxygen demand (COD), suspended solids (SS), ammonium nitrogen (NH4-N), and phenol) measured monthly in 2021.

Ibuprofen (IBP) is one of the most consumed drugs in the world. It is only partially removed in wastewater treatment plants (WWTPs), being present in effluent wastewater and sewage sludge, causing the widespread introduction of IBP as an emergent xenobiotic in different environmental compartments. This study describes the use of CSW11, recently described as an IBP degrader, through bioaugmentation processes for the removal of IBP from water under different conditions (additional carbon sources, various concentrations of glucose and IBP).
