Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: This study investigated the effect of suitable substrates on the removal of PAHs in constructed wetlands. One of the wetland systems (CW-D) achieved satisfactory and stable PAHs removal by 23.80%-31.18% compared to the control group after 120 days of operation. Microbial degradation was identified as the main PAHs removal mechanism, and the increased proportion of microbial degradation in CW-D resulted in higher PAHs removal. Root length and microbial diversity were found to be the two driving factors affecting PAHs removal. This study provides comprehensive insights into the importance of suitable substrates, as well as the related mechanism and driving factors for PAHs removal in constructed wetlands.

Summary: Tequila's increasing demand has led producers to develop faster production processes. There are two processes for sugar extraction in Tequila production: with or without cooking agave cores (TrP and NCP). Each process generates different vinasses. This work focuses on vinasses characterization from both Tequila production processes. The physicochemical parameters of vinasses from different processes were analyzed, with the findings indicating that the differences between each type of vinasses are more physicochemical than biological, influenced by the sugar extraction process.

Summary: The increasing production of biosolids from urban wastewater treatment poses pollution problems, and better management and disposal methods are needed. Composting biosolids with bovine manure and rice husks can yield an organic amendment for agricultural soils. This study analyzed a composting process with different treatments for 120 days and developed compost quality indexes (CQIs) based on 18 physicochemical, biological, and ecophysiological indicators. The CQIs, including the nitrification index and synthetic enzymatic index, differentiated the quality of the compost according to the treatments applied. The developed CQIs can be used to determine the quality of biosolids composting systems and reduce monitoring costs.

Summary: As the global population grows, the demand for food increases, leading to a strain on food production systems and soil degradation. Soil quality indexes (SQIs) have been developed to maintain and improve soil quality, but analyzing and comparing results has been historically difficult due to the variety of soils and SQIs. This study conducted a systematic review with meta-analysis on soil quality studies of agricultural soils, finding that chemical indicators were the most prevalent in SQIs and conventional soil management had negative effects on soil quality.

Summary: This study aimed to validate the removal of total petroleum hydrocarbons (TPH) in a pilot system. Both bioremediation and natural attenuation treatments were applied to six piles of oil-contaminated soil, and the removal of alkanes, polycyclic aromatics (PAH), TPH, and bacterial diversity were evaluated at different time points. The results showed that bioremediation was more effective in removing alkanes, PAH, and TPH compared to natural attenuation. The presence of Panicum maximum and secondary vegetation facilitated the development of beneficial soil microorganisms and improved the efficiency of TPH removal.

Summary: Recent studies have been mainly focused on using entomopathogenic fungi for biocontrol of ambrosia beetles, with limited research on the potential of bacteria as biocontrol agents against ambrosia fungi. Future research should further explore the antifungal activity of bacterial strains in harsh environments, isolate more effective strains with dual biocontrol effects, and determine the best application methods of biocontrol agents in the field. Integration of microbiome studies in pest and disease management strategies may provide tools to manipulate beetle and host plant microbiomes for reduced insect fitness.

Summary: Soil microbial community coalescence, the mixing and interaction of microbial communities, has been found to enhance the stability and complexity of rhizobacterial networks, leading to improved plant health and biomass. This study investigated the effects of different degrees of bacterial community coalescence on plant disease resistance by mixing soils from healthy and diseased habitats for watermelon planting. The results showed that mixing in more healthy soil reduced the plant disease index and increased biomass by improving the stability and complexity of the rhizobacterial network. Core taxa Nitrospirillum and Singulisphaera were enriched in the rhizosphere from healthy soils and played important roles in disease suppression and regulating the positive cohesion and modularity of the networks. Overall, these findings provide insights into the potential mechanism of microbial community coalescence for improving plant microbial community function and suggest new tools for enhancing plant fitness via soil microbiota mixing.

Summary: Collembolans, the diverse group of soil invertebrates, are affected by anthropogenic climate warming, which alters their diversity and density. In addition to abiotic stressors, changes in food availability, specifically the abundance of saprotrophic and mycorrhizal fungi, influence Collembola responses to climate warming. Collembolans prefer saprotrophic fungi but rely on mycorrhizal fungi when food sources are scarce. Understanding the mechanisms behind these dietary shifts in warm-dry and warm-wet soil conditions is crucial for predicting the impact of climate change on Collembola-fungal interactions.
