Summary: Members of the Proteobacteria can enter a viable but non culturable (VBNC) state as a survival strategy under stressful conditions. Using Vibrio parahaemolyticus as a model organism, distinct subpopulations in the VBNC state with different resuscitation potentials and proteomic profiles were identified. Deletion of the lactate dehydrogenase gene triggered cells to enter VBNC state, while lactate addition extended resuscitation potential. The ability to survive in VBNC state may be linked to overcoming oxidative stress.

Summary: It was found that Rhodococcus biphenylivorans TG9 enters a viable but nonculturable (VBNC) state under anaerobic conditions, leading to a significant reduction in metabolic activity and degradation ability. However, resuscitation by providing oxygen can restore the degrading capacity of TG9 in the VBNC state, providing a new strategy to cope with survival under anaerobic conditions.

Summary: In this study, brackish groundwater samples from the Inner Dinarides and Serbian crystalline core regions of western Serbia were analyzed to isolate and identify bacteria capable of degrading plastic and lignocellulose. The genetic types of the examined occurrences were HCO3-Na + K and HCO3-Ca, Mg, belonging to the cold and warm groundwater with various pH levels. Through next-generation 16S sequencing, the most abundant genera identified were Aeromonas and Exiguobacterium. The presence of plastic-degrading bacteria in the investigated groundwater suggests potential applications in bioremediation of polluted groundwater resources.

Summary: A new biobased flame retardant (MHPA) was synthesized by neutralizing magnesium hydroxide (MH) with phytic acid (PA). Adding MHPA to ethylene vinyl acetate (EVA) significantly improved the fire retardancy, smoke suppression, and mechanical properties of the composites. The combination of MHPA and MH exhibited excellent carbonization and expansion effects, contributing to the improved flame retardancy.

Summary: This study compared the fouling behaviors of a membrane bioreactor (MBR) operated at normal and sludge bulking stages, and explored the different mechanisms behind these behaviors. The results showed that the MBR could be stably operated for about 60 days without membrane cleaning in the normal stage, while daily membrane cleaning was required in the sludge bulking stage. Further characterizations revealed that the bulking sludge had lower dewaterability, smaller particle size, higher fractal dimension, higher viscosity, abundant filamentous bacteria, and different types of extracellular polymer substances (EPS). It was suggested that microbial community transition was responsible for the occurrence of sludge bulking, which in turn affected membrane fouling. Based on these findings, it was proposed that providing extra force to offset a chemical potential gap caused by foulant layer structure transition during sludge bulking is necessary to sustain filtration and prevent extremely high specific filtration resistance (SFR).

Summary: This study investigated the combined effects of polymeric aluminum chloride (PAC) and polyacrylamide (PAM) on sludge dewatering, aiming to uncover the underlying mechanisms. The co-conditioning of 15 mg g-1 PAC and 1 mg g-1 PAM achieved optimal dewatering performance, significantly reducing the specific filtration resistance (SFR) of the co-conditioned sludge. The findings provide insights into the improved dewatering performance and the thermodynamic mechanisms of sludge dewatering with different chemical conditioning.

Summary: The study found that Rpf of Micrococcus luteus can resuscitate and stimulate the growth of PCB-degrading bacterial populations, thereby improving the bioremediation efficiency of PCBs. Soil microcosms amended with Rpf and LS1 degraded PCBs 1.1-3.2 times faster than control microcosms. The degradation process mainly occurred through the HOPDA-benzoate-catechol/protocatechuate pathways. These results suggest that Rpf and resuscitated strains serve as effective additives and bio-inoculants for enhanced bioremediation, providing new approaches for large-scale applications of in situ bioremediation.

Summary: This study investigates a new approach to improve the anaerobic digestion of waste activated sludge (WAS) by combining fungal mash and free nitrous acid (FNA) pretreatment. The fungal strain Aspergillus PAD-2, which secretes superior hydrolase, was isolated from WAS and cultured in-situ on food waste to produce fungal mash. The solubilization of WAS by fungal mash achieved a high release rate of soluble chemical oxygen demand, and the combined pretreatment of fungal mash and FNA further enhanced sludge solubilization and methane production.

Summary: The recycling of wastewater with multiple pollutants is an urgent issue, and gravity-driven membrane separation with metal-organic frameworks (MOFs) as membrane modifications has shown great potential. In this study, a novel Ni-MOF membrane was prepared by synthesizing flower-like nickel-based MOF particles and assembling them on a nylon membrane. The Ni-MOF membrane exhibited superhydrophilic and underwater superoleophobic properties, and demonstrated significantly improved rejection rates for various dye solutions, oil-water emulsion, and microplastic wastewater, while maintaining long-term stability. These findings highlight the broad application prospects of Ni-MOF membranes in wastewater treatment.

Summary: This study inserted titanium oxide nanotubes into the interlayer space of 2D MXene-based membranes to prepare PMT membranes with excellent performance. The PMT membrane has outstanding hydrophilicity, high retention rates, and ultra-high permeability. It also exhibits excellent antifouling and self-cleaning properties. The incorporation of TiONT increased the interaction energy between the membrane and pollutants, thereby improving its antifouling performance. This novel 2D membrane shows great promise for large-scale continuous separations of oil/water emulsions.

Summary: Quorum quenching (QQ) is a novel technique for controlling biofouling in membrane bioreactors (MBRs) by disrupting quorum sensing (QS) and inhibiting biofilm formation. This study evaluated the effectiveness of the QQ strain Brucella sp. ZJ1, encapsulated in alginate beads, in mitigating biofouling. The results showed that MBR with QQ beads extended operation time by 2-3 times without affecting pollutant degradation, and these beads maintained approximately 50% QQ activity even after 50 days of operation.
