Summary: This study quantified the impact of subsurface conditions on CO2 foam, finding that increasing salt concentration significantly affects foam stability and CO2 molality. Additionally, increasing surfactant amount had negligible impact on CO2 molality. The CO2 foam exhibited non-Newtonian shear thinning behavior and showed potential for enhanced oil recovery and carbon storage in subsurface environment.

Summary: This study utilized a polyphasic taxonomy approach to accurately classify six strains within the Enterobacter cloacae complex (ECC). The 16S rRNA gene-based phylogeny failed to group all ECC species into a monophyletic cluster, while genome sequence-based phylogenetic approaches successfully grouped all species. A new species named Enterobacter pasteurii sp. nov. was proposed based on comprehensive genotypic and phenotypic characterizations.

Summary: The widespread use of synthetic pesticides has led to various issues, necessitating the development of new microbial derived insecticides for safe and environmentally-friendly pest control. This study evaluated the toxicity of a biosurfactant produced from Enterobacter cloacae on mosquito larvae and termites, finding that it exhibited larvicidal and anti-termite activity. The biosurfactant caused substantial tissue damage in the studied organisms. These findings suggest that the microbial biosurfactant has great potential for the control of mosquitoes and termites.

Summary: The study revealed that high CEC montmorillonite clay minerals can adsorb more bacterial cells, thus providing a certain level of protection for microorganisms against Pb2+ stress. However, the addition of Enterobacter sp. actually increased the residual Pb2+ concentration in the solution by 7.5%, indicating that the adsorption of typical soil bacterium on clay minerals has a certain impact on the adsorption of Pb.

Summary: The widespread application of polysaccharides is limited by low syneresis impact. Our study demonstrated that the thermodynamic instability of kappa-carrageenan polysaccharide is the origin of syneresis and investigated the effects of KCl salt on critical concentration and LCCT. The difference between Tg and LCCT serves as the thermomotive force behind the syneresis of many colloidal gels.

Summary: In this study, a novel exopolysaccharide (EPS) derived from Alteromonas macleodii Mo 169 was used to prepare selenium nanoparticles (SeNPs). The synthesized nanoparticles exhibited good dispersion and spherical shape, with an average size of 32 nm. The cytotoxicity of the EPS and EPS/SeNPs bio-nanocomposite was evaluated on human keratinocyte and fibroblast cell lines, showing no significant cytotoxicity for EPS alone and only mild cytotoxicity for the bio-nanocomposite at higher concentrations. Moreover, the non-cytotoxic concentrations of EPS/SeNPs bio-nanocomposite demonstrated a significant cellular antioxidant effect on the tested cell line, reducing ROS levels by up to 33.8%.

Summary: This study identified a new dinoflagellate, Heterocapsa sp. AC210, as a producer of novel exopolysaccharides (EPS). The cultivation and EPS production in a bioreactor were thoroughly evaluated. The EPS consisted of seven different sugar monomers, including rare fucose and glucosamine not previously reported in dinoflagellates' EPS. The EPS also exhibited a high sulphate content, which is associated with biological properties. Cytotoxicity tests showed that the EPS did not reduce cell viability at concentrations up to 1 g L-1. Furthermore, antioxidant and anti-inflammatory assays demonstrated the potential application of the EPS in cosmeceutical and biomedical fields, as it reduced intracellular reactive oxygen species and IL-8 and IL-6 secretion in keratinocytes.

Summary: The marine isolate Alteromonas macleodii Mo 169 secretes an exopolysaccharide (EPS) that can be used to synthesize and stabilize silver and gold nanoparticles (AgNP and AuNP). The EPS possesses negatively charged functional groups, allowing it to function as a reducing agent and stabilizer for metallic nanoparticles. The synthesized nanoparticles showed promising physical-chemical and biological characteristics, including a polysaccharide layer that reduced aggregation and cytotoxicity. These findings demonstrate the potential of A. macleodii Mo 169 EPS for the development of novel biomaterials for wound care and other applications.

Summary: For the production of polyhydroxyalkanoates (PHA) using nitrogen-rich feedstocks, the typical strategy of restricting cell growth by nitrogen limitation is not applicable. In this study, Donnan dialysis was evaluated as an alternative method to remove excess nitrogen ions by separating ammonium ions from volatile fatty acids in the media. The use of Fumasep and Ralex membranes showed better performance in terms of ammonium extraction compared to Ionsep.

Summary: The polysaccharide FucoPol has shown great potential as a biomaterial in the biomedical field due to its good mechanical properties, biocompatibility, and anti-inflammatory activity. In this study, FucoPol hydrogel membranes (HMs) were loaded with caffeine or diclofenac sodium using diffusion or mixing methods. The diffusion method led to higher caffeine loading, while the mixing method resulted in higher diclofenac sodium loading. The HM1_DCAF membranes had increased mechanical and rheological parameters compared to the HM1_DDS membranes, possibly due to leaching during the drug-loading process. The release profiles showed fast release for diffusion-loaded membranes and prolonged release for mixing-loaded membranes. These findings support the suitability of FucoPol HMs as platforms for topical drug delivery.

Summary: In this study, FucoPol, a fucose-rich polyanionic polysaccharide, was used for the preparation of hydrogel membranes (HMs) with Fe3+ as a crosslinking agent. The influence of Fe3+ and FucoPol concentrations on the strength of HMs was evaluated. The results showed that the FucoPol concentration had a more significant effect on the HMs' strength than the Fe3+ concentration. HMs with different FucoPol concentrations exhibited different microstructures and mechanical properties.

Summary: The current study investigates the spray-drying formation of microencapsulated geraniol powder using the exopolysaccharide EPS-K1B3 produced by Halomonas caseinilytica K1 as the wall material. The antimicrobial activity of the functional emulsions prepared at different pH values was evaluated against Listeria innocua and Escherichia coli. The results show that the microencapsulated geraniol powder exhibited prolonged antimicrobial efficacy, with the highest activity observed at pH 5 against L. innocua. This highlights the importance of pH in the functional properties of geraniol microcapsules.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
