Reduction of ethanol content in wine with an improved combination of yeast strains and process conditions
Food Microbiol. 2023 Oct;115:104344. doi: 10.1016/j.fm.2023.104344. Epub 2023 Jul 25.ABSTRACTOne interesting strategy to address the increasing alcohol content of wines, associated with climate change, is to reduce the ethanol yield during fermentation. Within this strategy, the approach that would allow the clearest reduction in alcohol content is the respiration of part of the grape sugars by yeasts. Non-Saccharomyces species can be used for this purpose but suffer from a limited ability to dominate the process and complete fermentation. In turn, Saccharomyces cerevisiae shows a high production of acetic acid under the g...

Simultaneous degradation of microplastics and sludge during wet air oxidation
In this study, three common MPs (polyethylene, polystyrene, and polyethylene terephthalate, which are called PEMPs, PSMPs, and PETMPs) were added into the sludge samples (1 g MP in 180 mL sludge), to test the effects of WAO on sludge and MPs. The results showed that WAO simultaneously degraded sludge and the PEMPs, and the two degradation processes were relatively independent when oxygen was supplied adequately. The dissolution of PSMPs and organic matter in sludge was not affected by each other, but the degradation rate was slowed down due to the interaction of ketones and benzene compounds. The hydrolysis of sludge and P...

A novel PPAR β/FFA1 dual agonist Y8 promotes diabetic wound healing
CONCLUSION: Our results suggest that PPARβ/FFA1 dual agonist Y8 has the effect of promoting the healing of diabetic ulcer wounds in vivo and in vitro, and its therapeutic effect is better than that of single-target agonists.PMID:37562666 | DOI:10.1016/j.ejphar.2023.175934

C-H functionalization of quinoline N-oxides catalyzed by Pd(II) complexes: a computational study
Phys. Chem. Chem. Phys., 2023, Accepted Manuscript DOI: 10.1039/D3CP02445H, PaperPaulo J. Costa, Frederico F. Martins, Chao Pi, Xiuling Cui, Maria Jos é Calhorda Pd(II) catalysts, particularly the acetate salt in acetic acid, tended to favor the regioselective C-H activation of quinoline N-oxides (QOs) at the C2 position. However, Pd(II)Cl2 was shown to catalyze... The content of this RSS Feed (c) The Royal Society of Chemistry

Citrus honeys from three different regions of Turkey: HPLC-DAD profiling and in vitro enzyme inhibition, antioxidant, anti-inflammatory and antimicrobial properties with chemometric study
The objectives of the present study are to compare the phenolic profiles and biological activities of 15 citrus honey samples from three different locations in Turkey using a chemometric approach. The HPLC-DAD analysis was used to determine phenolic profiles. Nineteen phenolic compounds were identified. Gallic acid (107.14-717.04 μg/g) was recorded as the predominant compound. AF (Antalya-Finike) had the highest antioxidant activity in ABTS•+ (IC50: 18.01±0.69 mg/mL), metal chelating (IC50: 6.20±0.19 mg/mL) and CUPRAC (A0.50: 12.05±0.68 mg/mL) assays, while it revealed the best anti-inflammatory activity against COX-...

Green Additives in Chitosan-based Bioplastic Films: Physical, Mechanical, and Chemical Properties
ChemSusChem. 2023 Aug 7:e202300585. doi: 10.1002/cssc.202300585. Online ahead of print.ABSTRACTTo switch to alternatives for fossil-fuel-based polymer materials, renewable raw materials from green resources should be utilized. Chitosan is such a material that is a strong, but workable derivative from chitin, obtained from crustaceans. However, various applications ask for specific plastic properties, such as certain flexibility, hardness and transparency. With different additives, also obtainable from green resources, chitosan-based composites in the form of self-supporting films, ranging from very hard and brittle to soft...

Valorisation of the residual aqueous phase from hydrothermally liquefied black liquor by persulphate-based advanced oxidation
Chemosphere. 2023 Aug 4:139737. doi: 10.1016/j.chemosphere.2023.139737. Online ahead of print.ABSTRACTHydrothermal liquefaction of Kraft black liquor is a promising method for the production of valuable organic chemicals. However, the separation of the biochar and biocrude leaves a residual aqueous phase in large volumes, which needs to be properly managed to make the process profitable. In this work, the persulphate-based advanced oxidation was assessed, for the first time ever, as a pretreatment of this aqueous phase to reduce its content of phenolic compounds and alcohols, which hinder further valorisation strategies. R...

Effects of deacetylation degree of chitosan on the structure of aerogels
Int J Biol Macromol. 2023 Aug 3:126123. doi: 10.1016/j.ijbiomac.2023.126123. Online ahead of print.ABSTRACTChitosan aerogels, obtained by (supercritical) CO2 drying of hydrogels, are novel adsorbents because of their large surface area and high porosity. Intrinsic properties of chitosan such as molecular weight (MW) and degree of deacetylation (DDA) had large impacts on the characteristics of chitosan aerogels. Although there are a few studies about the effects of solely DDA or MW on aerogel structure, none of them has focused on the mutual effects. The study aims to investigate the combined effects of MW and DDA of chitos...
