Development and Characterization of Antimicrobial Chitosan/Polyethylene Oxide/Bacterial Cellulose Nanofibers

Polymers, Год журнала: 2025, Номер 17(5), С. 693 - 693

Опубликована: Март 5, 2025

This study introduces novel chitosan (CS) and polyethylene oxide (PEO) copolymers reinforced with bacterial cellulose (BC) to fabricate nanofibers using the electrospinning method. SEM analysis confirmed uniform nanofiber formation, CS/PEO/BC (~240 nm) exhibiting a larger diameter than CS/PEO ones (~190 nm). FTIR spectroscopy BC integration, while Differential scanning calorimetry indicated minimal impact on glass transition temperature. Notably, as compared nanofibers, demonstrated superior swelling capacity, accelerated biodegradation, enhanced mechanical (i.e., tensile) properties, maximum stress strain values of ~3.41 MPa ~0.01% vs. ~2.14 ~0.01%. Antimicrobial assays activity against strains, biocompatibility tests showed high cell viability at day seven (99.26% for nanofibers). These findings highlight potential promising candidates tissue engineering, offering improved strength, biodegradability, antimicrobial properties.

Effect of different biomass on properties of slurry fuel based on petroleum coke and municipal sludge

Petroleum Science and Technology, Год журнала: 2025, Номер unknown, С. 1 - 19

Опубликована: Янв. 5, 2025

To produce high-quality slurry fuel from petroleum coke and municipal sludge, the effects of various biomass materials on characteristics were investigated experimentally. The used in this experiment classified into three categories: monosaccharides (e.g., glucose), starch-based potato residue), cellulose-based corn straw, water hyacinth, rice husk, kelp). results revealed significant variations properties influenced by different types their respective proportions. Increasing content led to a decrease solid concentration bubble sludge (bubble-PCSS). However, reduction was moderate with biomass, whereas it pronounced especially kelp. addition significantly improved pseudoplastic rheological slurry. Specifically, when incorporated, flow characteristic index approached 0.7. Optimal stability bubble-PCSS achieved at 2% level biomass. In contrast, using such as kelp, husks, they required 3-4% reach optimal stability, which somewhat less favorable than that

Influence of Modification of Cysteine Residues in the Carbohydrate-Binding Domain on Cellulase Activity: Achieving Enhanced Performance and pH-Sensitive Recovery

Journal of Agricultural and Food Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 19, 2025

The conversion of cellulosic biomass into fermentable sugars represents a pivotal stage in the environmentally friendly and sustainable production clean fuels chemicals. In this paper, new strategy to enhance enzyme performance was proposed. This can achieve pH-sensitive recovery cellulase while improving catalytic activity stability enzyme. achieved by means chemical modification cysteine residue (−SH) carbohydrate-binding domain (CBD) with PEG-based modifier (Mal-PEG-FA). It shown that altered conformation cellulase, which significantly improved efficiency CBD enzyme, turn promoted particular, modified molecular weight 10 k demonstrated highest level activity, an increase 130.02% comparison native cellulase. Ultimately, effective aqueous phase system accomplished adjusting pH system. After five cycles, still maintained 81.0% its initial enzymatic activity. research is significant strategic importance for promotion efficient utilization.
