Abstract ：
The disposal of discarded vulcanized natural rubber waste has presented substantial environmental challenges. This study aimed to investigate the degradation of vulcanized natural rubber through the utilization of enriched bacterial consortia with NRE3 derived from the soil. The highest weight loss of 38.84 % was achieved with NRE3 after four weeks of incubation. Additionally, the crosslinking density of rubber decreased by 32.3 % and the tensile strength decreased from 69.1 to 9.5 MPa. SEM analysis revealed the presence of significant cracks and holes on the surface of vulcanized natural rubber. Moreover, FT-IR and XPS analyses demonstrated a decrease in the sulfur (S) and carbon (C) content of the rubber, while the oxygen (O) content increased. The concentration of SO42- in the medium increased from 478.37 to 840.26 mg/L, indicating the collapse of the rubber structure. The NMR and GC-MS findings indicated the presence of degradation products, specifically polyisoprene oligomers and terpenoids. Through high-throughput sequencing analyses, Acinetobacter, Chryseobacterium, Stenotrophomonas and other bacterial were discovered in NRE3. Based on the chemical structure characterizations and molecular analyses, a degradation pathway was proposed. These findings pave a way for utilizing rubberdegrading microorganisms present in soil and contribute to the establishment of a biodegradation method for disposing of vulcanized rubber waste.

Abstract ：
Sulphate-reducing microorganisms, or SRMs, are crucial to organic decomposition, the sulphur cycle, and the formation of pyrite. Despite their low energy-yielding metabolism and intense competition with other microorganisms, their ability to thrive in natural habitats often lacking sufficient substrates remains an enigma. This study delves into how Desulfovibrio desulfuricans G20, a representative SRM, utilizes photoelectrons from extracellular sphalerite (ZnS), a semiconducting mineral that often coexists with SRMs, for its metabolism and energy production. Batch experiments with sphalerite reveal that the initial rate and extent of sulphate reduction by G20 increased by 3.6 and 3.2 times respectively under light conditions compared to darkness, when lactate was not added. Analyses of microbial photoelectrochemical, transcriptomic, and metabolomic data suggest that in the absence of lactate, G20 extracts photoelectrons from extracellular sphalerite through cytochromes, nanowires, and electron shuttles. Genes encoding movement and biofilm formation are upregulated, suggesting that G20 might sense redox potential gradients and migrate towards sphalerite to acquire photoelectrons. This process enhances the intracellular electron transfer activity, sulphur metabolism, and ATP production of G20, which becomes dominant under conditions of carbon starvation and extends cell viability in such environments. This mechanism could be a vital strategy for SRMs to survive in energy-limited environments and contribute to sulphur cycling. This study uncovers a unique mechanism where a non-phototrophic sulphate-reducing microorganism adapts to environments with limited or depleted substrates. It does this by harnessing photoelectrons from semiconducting minerals that coexist extracellularly, which are then used for energy production and metabolism. image

Abstract ：
Copper-based small-pore zeolites catalysts are the promising candidate catalysts for NOx abatement in current diesel vehicles with Chinese VI standards, due to the excellent NH3-SCR catalytic performance, hydrothermal stability, nitrogen selectivity and wide temperature window. However, the catalytic activity of copper-based small-pore zeolites is still significantly affected by sulfur oxides emitted from diesel vehicles, and even the irreversible deactivation occurs. The SO2-poisoning of Cu-based small-zeolites is mainly due to the accumulation of surface ammonium sulfate and sulfation of Cu active site sites. In this review, the research status of the structure and active sites of copper-based small-pore zeolites catalysts is summarized, and the sulfur poisoning mechanism of copper-based small-pore zeolites catalysts is discussed. Moreover, the research advance in the improvement of sulfur resistance of catalysts and the regeneration of sulfur-poisoned catalysts is also illustrated. The systematic understanding of mechanism of sulfur poisoning and regeneration is important for the design of novel, efficient catalyst. It is pointed out that the study on sulfur poisoning mechanism and regeneration mechanism of copper-based small-pore zeolites catalysts, as well as the synergistic effect of various poisoning factors and corresponding deactivation mechanism, are the main research directions for copper-based zeolites to be practically applied to ultra-low emission of nitrogen oxides in diesel vehicle exhaust in the future.

Abstract ：
The ferrite process has been developed to purify wastewater containing heavy metal ions and recycle valuable metals by forming chromium ferrite. However, organic matter has an important influence on the crystallization behavior and stability of chromite synthesized from chromium-containing wastewater. We focused on the in-fluence and effect mechanism of two typical organic acid salts (citrate (CA) and tartrate (TA)) on the process of chromium mineralization. It was found that the presence of organic matter leads to the increase of the residual content of Cr in CA system (0.50 mmol/L) and TA system (0.61 mmol/L) in the solution, and the removal of chromium was mainly due to the surface adsorption of Fe(III) hydrolysate. The decreased crystallinity of mineralized products is ascribed to the completion of organic compounds with Fe(II) and Fe(III), which hinders the formation of ferrite precursors. There was bidentate and monodentate chelation between -COO-and metal ions in the CA system and TA system respectively, which resulted in a stronger affinity between CA and iron. This study provides the underlying mechanism for Cr(III) solid oxidation by the ferrite method in an organic matter environment and is of great significance to prevent and control chromium pollution in the environment.

Abstract ：
Exclusion-zone (EZ) phenomenon generally refers to a long-range exclusion of particles at the interface between a hydrophilic surface and a bulk aqueous solution. Although the rejection of dissolved substances such as dyes and ions has previously been reported, it is still disputable till now due to the limitation of the optical microscopic observation. The controversy on the solute exclusion not only leads to significant divergence on our understanding of the EZ formation mechanisms, but also constrains the application of EZ phenomenon in physical, chemical, biological, and environmental processes. Therefore, here we propose a UV/Vis spectrophotometric method to clarify the occurrence of solute exclusion in the presence of hydrophilic surface. The consistence of the microscopic and UV/Vis spectrophotometric results in both particles and solutes proves that the UV/Vis spectrophotometric method is suitable for the quantitative characterization of the EZ formation process. Through this spectrophotometric method, we found the exclusion of particles and solutes with different exclusion behavior near hydrophilic surface. We expect this work will provide a different insight in understanding the underlying mechanisms for EZ formation and the long-range interactions between water and hydrophilic surface, as well as the possible application of this exclusion phenomenon in relevant fields.
