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: The feasibility of utilizing an immobilization approach to enhance the PCBs degradation performance of a resuscitated strain Streptococcus sp. SPC0 was evaluated in this study. The results showed that the mixed matrix of polyvinyl alcohol (PVA) and sodium alginate (SA) provided a porous microstructure for SPC0 colonization and proliferation, leading to enhanced removal of PCBs through simultaneous adsorption and biodegradation. Immobilized SPC0 demonstrated 1.0-7.1 times higher PCB removal than free cells, with higher concentrations achieving more effective removal. Moreover, the immobilized SPC0 showed excellent stability and reusability after four cycles of reuse.

Summary: In this study, the resuscitation promoting activity of Rpf protein from N. halophila was reconstituted in vitro and in vivo. It was found that the Rpf protein had a significant effect on resuscitating the viable but non-culturable (VBNC) N. halophila. Knocking out the rpf gene in N. halophila resulted in slower growth rate and shorter spores compared to the wild-type strain. This study provides a foundation for the exploitation of actinomycetes resources using Rpf protein from N. halophila.

Summary: A new 4C2NP degrader NyZ417 was isolated and identified as a member within Cupriavidus genus, which utilized 4C2NP as the sole nitrogen source for growth and degraded it through an oxidative pathway. The monooxygenase encoding gene onpA(NyZ417) from its complete genome was confirmed to be involved in 4C2NP biotransformation. This study not only elucidated a functional gene for 4C2NP degradation but also provides a foundation for cleaning up 4C2NP residues in the environment.

Summary: A low-cost approach using in-situ reduction strategy was developed to prepare PDA@NixCo100-x nanotubes, which contained active NiCo nanoparticles encapsulated in the inner wall. The optimized PDA@Ni25Co75 nanotubes exhibited excellent photocatalytic performance, achieving 99.3% degradation of methyl orange and 95.7% degradation of 4-nitro phenol in 10 and 15 minutes, respectively, outperforming previous materials reported in literature. The self-sustained high-density PDA@Ni100Co0 nanotube arrays obtained by removing the membrane structure were efficient catalysts for pollutant capture. This cost-effective nanocatalyst approach has great potential for large-scale applications in environmental remediation, demonstrating significant innovation and contribution to the field.

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.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
