Summary: Gordonia sp. SCSIO19801 is a bacterium isolated from the South China Sea that can effectively utilize phenanthrene as the sole carbon source. It degrades phenanthrene via the salicylate metabolic pathway and has the ability to utilize other aromatic compounds. These characteristics make it a potential candidate for biodegradation of petroleum hydrocarbons in marine environments.

Summary: Understanding the degradation potentials in PAHs-contaminated sites is essential for effective bioremediation strategies. The pahE gene has been identified as a better functional marker for assessing the biodegradation potential of indigenous PAHs-degrading bacteria. This study investigated the distribution of pahE and its relationship with environmental factors across different PAHs-polluted ecosystems. The results provide insights into the ecophysiology and distribution of aerobic PAHs-degrading bacteria in contaminated sites.

Summary: Halotolerant strain CO100 of Staphylococcus sp. isolated from contaminated sediments in Tunisia showed efficient hydrocarbon degradation ability and synthesized a lipopeptide biosurfactant BS-CO100 with strong tensioactive properties under various conditions, non-cytotoxic to human cells. BS-CO100 also exhibited anti-biofilm and anti-adhesive activities, making it a promising candidate for bioremediation of oil-polluted areas, even under saline conditions.

Summary: Environmental pollution caused by polycyclic aromatic hydrocarbons (PAHs) is high-risk due to their carcinogenic, teratogenic, and mutagenic properties, and has been widely studied. Phenanthrene (PHE), a low molecular weight PAH with three benzene rings, is a common contaminant in the environment. In this study, a PHE-degrading bacterium called Stenotrophomonas indicatrix was isolated from industrial contaminated soil using enrichment culture techniques. This is the first demonstration of the ability of S. indicatrix to degrade and mineralize PHE.

Summary: The palladium-catalyzed cyclotrimerization of ortho-silylaryl triflates is a well-established method for synthesizing polycyclic aromatic hydrocarbons with triphenylene cores. In the reaction of pyrene with o-silylaryl triflates, higher homologues with eight- and ten-membered rings were unexpectedly formed along with the trimer, and a protocol was developed to isolate all members of this series. This novel class of PAHs was thoroughly investigated using various techniques, including X-ray diffraction, UV/Vis and fluorescence spectroscopy, and theoretical calculations. A mechanistic proposal for the formation of all higher cyclooligomers was supported by density functional theory (DFT) calculations.

Summary: A comparative study was conducted on the total bacterial communities and cultivable polycyclic aromatic hydrocarbons (PAH) degrading bacteria in different functional zones in Moscow and Murmansk. The results showed variations in the PAH composition in road and leaf dust. Analysis of the microbial communities indicated that minor degrading strains may play a key role in PAH degradation.

Summary: Polycyclic aromatic hydrocarbons (PAHs), particularly chrysene, have toxic effects on the liver by increasing relative liver weight and elevated serum ALT levels; the hepatotoxicity of chrysene is dependent on the aryl hydrocarbon receptor (AhR), while Nrf2 plays a crucial role in protecting against oxidative liver injury induced by chrysene.

Summary: Although the association between single PAHs exposure and telomere length has been studied, the relationship between mixed PAHs exposure and telomere length in the general population is still uncertain. This study analyzed 8 PAHs and their correlation with telomere length, finding that mixed PAHs exposure was negatively associated with telomere length. Specifically, 2-napthol and 2-fluorene concentrations showed a significant negative correlation with telomere length. These findings indicate that PAHs may have a negative impact on telomere length in the general population.

Summary: This study used Escherichia coli BL21(DE3) as a model to investigate the adaptation process of microbial cells during transfer from Luria-Bertani medium to minimal medium. The findings revealed that sequential transfers from minimal medium to fresh medium accelerated cell growth rate and led to the occurrence of genetically adapted cells, contributing to a shortened lag time. Furthermore, genetic heterogeneity was observed in microbial populations during adaptation to new environments, enhancing microbial adaptability.
