Summary: The study focused on eight bacterial consortia developed from PAH-contaminated sediments, with consortium ACDMRT-8 showing efficient degradation of naphthalene, phenanthrene, fluoranthene, and pyrene within a short period. While Proteobacteria dominated the bacterial communities in all consortia, the diversity varied based on enrichment conditions and types of PAHs provided. Pseudomonas species were found to be abundant in four consortia, facilitating degradation of all four PAHs.

Summary: This study demonstrated that a co-culture of Hydrogenophaga eletricum and Methylobacillus sp. was the most efficient in degrading epoxiconazole, while none of the tested bacterial combinations showed potential to biodegrade fludioxonil. Metabarcoding analysis indicated that the biodegradation of epoxiconazole may be driven by less abundant phylotypes in the community.

Summary: We have achieved a successive alpha-expansion of pyracylene to form boat-shaped polycyclic compounds. The resulting compounds exhibit unique structural features, as revealed by X-ray crystallographic analysis. Experimentally and computationally, we observed significant red-shifted absorption bands in the UV/Vis spectra and multiple redox events, indicating a progressive narrowing of the HOMO-LUMO gap and evolution of the electronic structure and aromaticity.

Summary: This study investigated the interactive relationships among PAHs, PDGs, and bacterial communities in the rhizosphere soil and rice grain in PAH-contaminated paddy soil. It was found that PAHs played a critical role in shifting community composition in both soil and rice grain, while the abundance and diversity of PDB varied between the two environments. Additionally, different keystone species were identified in the soil and rice grain, with Pseudomonas and Sphingomonas being highlighted as important bacteria associated with PAH degradation in rice grain.

Summary: This study investigated the effects of different concentrations of a fresh PAH mixture and an aged natural PAH mixture on bacterial communities and PAH degradation potential in the Echinacea purpurea rhizosphere. The results showed that the enrichment of Actinobacteria and Patescibacteria in the rhizosphere was associated with enhanced PAH degradation potential, and different PAH mixtures favored different PAH-degrading bacteria. The study also highlighted the importance of soil nutrients and pH in shaping the PAH-degrading bacterial community in the rhizosphere.

Summary: This study investigated the anaerobic degradation activity of sulfonamide (SA) compounds and the associated bacterial community in wetland sediments. The results showed that only sulfamethoxazole (SMX) could be effectively degraded, and the degradation rate was faster in sediments with higher levels of SA contamination. The DNA-stable isotope probing (SIP) technique revealed that the active SMX-degrading bacteria were dominated by Proteobacteria in some sediments and by Firmicutes in others.

Summary: This study conducted metagenomic analysis on industrially contaminated soils, revealing that the abundance of PAH degradation genes and taxa did not differ significantly between soils with different pollution levels. The most abundant taxa carrying PAH degradation genes were actinobacteria from the Terrabacteria group. In addition to well-known PAH degraders such as Gordonia and Rhodococcus, other microbes like Azoarcus, Burkholderia, and Variovorax were found to possess genes related to PAH degradation, highlighting the non-specific and multifunctional nature of metabolic pathways encoded in these microorganisms.

Summary: This study aimed to construct consortia of Isochrysis galbana and bacteria with increased resistance to light stress. Four bacterial strains were found to promote algal growth and mitigate photoinhibition in I. galbana cells. Further analysis showed that the microalgal-bacterial consortia had higher efficiency of excitation energy capture and affected accumulation of proteins and polysaccharides in I. galbana cultures.

Summary: The study identified five bacterial consortia capable of degrading different PAHs, with consortium TC showing the highest efficiency in pyrene degradation and tolerance to high concentrations of pyrene and various heavy metals. Pseudomonas was the dominant genus in consortium TC, GS, and PL, while Achromobacter and Enterobacteriaceae were predominant in consortium PG and GD, respectively. Overall, consortium TC could be used for synergistic biodegradation of HMW PAHs and in situ bioremediation of sites contaminated with both PAHs and heavy metals.

Summary: Photocatalytic production of H2O2 is a potential green route to a greener future. However, the productivity is limited by rapid electron-hole separation and low oxygen reduction activity. In this study, a series of carbon nitrides with covalently bonded dual-functional ligands were designed to enhance H2O2 production and stability. The best-performing carbon nitride showed a high production rate and excellent stability. Mechanistic studies revealed that H2O2 was produced through a 2e(-) oxygen reduction reaction route. The excellent photocatalytic performance was attributed to the dual-functional ligand.

Summary: This study investigated the potential of indigenous microbial flora in salt-affected agroecological zones of Pakistan to enhance wheat production in saline areas. Bacterial strains with multiple characteristics were selected to develop a halotolerant bacterial consortium, which showed significant improvement in plant growth parameters. Fungal strains were also used separately and showed positive correlation with agronomical parameters. Field trials indicated the efficiency of these microbes in enhancing wheat growth. Promising results indicate the possibility of developing saline-specific biofertilizers and sustainable agriculture practices.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
