Summary: VR is a byproduct of crude oil vacuum distillation, primarily used for the production of syn-gas, hydrogen, heavy fuel oil for power generation and shipping. Due to its high sulfur content, desulfurization is necessary according to emission standards. Detailed molecular characterization of sulfur species in VR can be achieved using high-resolution FT-ICR MS, enabling classification and understanding of the sulfur structures present.

Summary: The leaf essential oil of Michelia formosana exhibits antifungal activity against wood decay fungi. Four sesquiterpenoids, including guaiol, bulnesol, and beta-elemol, showed higher antifungal activity against brown-rot fungus Laetiporus sulphureus and white-rot fungus Lenzites betulina. The molecular structure of these sesquiterpenoids contains the hydroxyisopropyl group. The findings suggest that sesquiterpenoids from the leaf essential oil of M. formosana have the potential to be used as natural fungicides for decay control of lignocellulosic materials.

Summary: This study investigated the immune response of vaccinated individuals and COVID-19 patients, and found that the affinity maturation rate of antibodies is higher after vaccination than after a natural infection. The results showed that Sputnik V vaccine can induce high-avidity IgG that persists for at least 6 months, providing long-lasting protection. These findings support the choice of a 4-6 month time period for booster immunization after vaccination or previous illness.

Summary: The ability of different ecophysiological groups of white rot fungi to degrade phthalic acid esters (PAEs) was studied. It was found that wood-destroying saprotrophs such as Trametes hirsuta and Steccherinum ochraceum can rapidly biodegrade diethylhexyl phthalate (DEHP), while litter saprotroph Crucibulum laeve efficiently transforms dibutyl phthalate (DBP). All fungi showed high sensitivity to diethyl phthalate (DEP), with Trametes hirsuta being the most resistant. The study also revealed the formation of various metabolites, including ionol, when PAEs are present in the medium.

Summary: A comparative analysis of fatty acids and volatile organic compounds in skimmed cow's milk fermented by different probiotic strains was conducted. The differences between strains were complex and not solely attributed to individual fatty acids. The nutritional and biological value of the fermented milk samples varied among the different strains. Analysis of volatile organic compounds revealed that odor-forming compounds were mainly fatty acids and their reaction products. The aroma of the fermented milk products coincided with the organoleptic assessment, exhibiting a typical yogurt and curdled milk flavor with floral and fruity notes.

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.
