Summary: In this study, fruit seeds of pomegranate cultivar Granata were extracted and analyzed to obtain information about their composition. The oily phase extracted from the seeds showed the presence of conjugated isomers of linolenic acid (CLNA isomers), which adds value to this traditionally considered waste. Different extraction methods were used, and the resulting oils were evaluated for their chemical composition. The prevalence of punicic acid in the triacylglycerol mixture was observed, with a higher content in the extract obtained by supercritical CO2.

Summary: Lipases are essential enzymes involved in the hydrolysis of triacylglycerol into fatty acids and have versatile applications, including biodiesel production. To maintain their stability and activity, lipases need to be immobilized on insoluble supports, with mesoporous silica nanoparticles being a promising option due to their thermal and mechanical stability, controlled textural characteristics, and surface functionalization capabilities.

Summary: This study revealed the accumulation of tricetin and tricetin 4'-O-glucoside in pomegranate floral tissues, specifically in anthers. Comparative transcriptome analysis identified 10 UGTs that are responsible for the glucosylation of tricetin, with PgUGT76Z1 and PgUGT73AL1 specifically glucosylating tricetin at the 4'-O position. Phylogenetic analysis suggested a convergent evolution of these tricetin UGTs. The identification and characterization of PgUGT76Z1 and PgUGT73AL1 provide insights into tricetin glucosylation and offer the potential for large-scale production of tricetin 4'-O-glucoside for further study of its bioactivities.

Summary: In this study, 75 members of the pomegranate ANS family were identified and categorized into four groups based on evolutionary relationships. These genes were unevenly distributed on seven chromosomes and most proteins were acidic and unstable. The proteins had alpha-spiral and irregular curl as the main structural elements, and conserved domains such as DIOX-N subfamily and 2OG-FeII_Oxy subfamily. The expression of pomegranate ANS genes was specific to variety and growth period.

Summary: This study investigated the fruit phenotypic and genetic variability, and relationships in 26 Greek and foreign pomegranate cultivars/accessions. Results showed low variability at both phenotypic and genotypic levels. The association study between phenotypic traits and molecular markers obtained using Multiple Regression Analysis could be valuable for marker-assisted breeding programs.

Summary: The pomegranate U-box gene family was identified and categorized into four groups based on the U-box domain. They were found to be unevenly distributed among the chromosomes and showed collinear duplications with Arabidopsis thaliana genome. Furthermore, the expression of these genes in pomegranate was induced by abiotic stressors. These findings provide valuable insights into the functional divergence of U-box genes in Punica granatum L.

Summary: The cooperation of biocatalysis and chemocatalysis in a catalytic cascade reaction has been widely studied. However, practical applications are hindered by enzyme fragility, poor compatibility between carriers and enzymes, and limited catalytic efficiency. In this study, a biomimetic cascade nanoreactor (GOx@COFs@Os) was developed, integrating glucose oxidase (GOx) and Os nanozyme with covalent organic framework (COF) capsules. The GOx@COFs@Os capsule provided a spacious microenvironment to retain GOx activity and protect it from incompatible environments. The COF capsule also improved substrate affinity and mass transfer efficiency, resulting in significantly improved catalytic efficiency compared to the free cascade system. Moreover, the biomimetic cascade capsule was successfully used for glucose monitoring, glutathione sensing, and bisphenol S detection. This strategy provides a new avenue for improving biocatalytic cascade performance and expanding its applications in various fields.

Summary: Adding polymers to injection water can increase viscosity and enhance oil recovery, but the adsorption of polymer to mineral surfaces may counteract these effects. The adsorption of HPAM molecules to silica and alumina surfaces varies, with Ca2+ ions on the silica surface causing increased adsorption by forming strong complexes with carboxyl groups on the polymer. The adsorption process is believed to involve a two-step process, with a primary adsorption followed by a slower secondary process involving rearrangements of adsorbed polymer molecules.

Summary: The study characterized the in-situ microscopic responses of organic layers on calcite surfaces to brines of different salinity, showing that the organic layers remain stable in high-salinity brines, desorb and swell in low-salinity brines, with the stiffness of the organic layers directly proportional to brine salinity. The observations were explained by the 'salting-out' effects, indicating the importance of destabilizing the organic layer for designing successful improved oil recovery strategies.

Summary: Natural molecules adsorbed on rock surfaces have a significant impact on geological processes such as oil recovery and underground CO2 storage. However, current geochemical models often overlook the formation and stability of these molecules. In this study, the authors use analytical techniques to investigate the deposition and desorption mechanisms of surface-active molecules on underground minerals, as well as their dependence on the composition of aqueous solutions.

Summary: In this study, a 2.5D glass microchannel coated with calcite particles was used to mimic the multiple porosity length scales and surface heterogeneity of carbonate reservoirs. The results showed that flooding with high-salinity water at varying temperatures and durations can effectively enhance the liberation of crude oil in the reservoir. The experiment also revealed that wall roughness in the microscale model plays a more significant role in oil retention than surface chemistry.
