Cuticle function is closely related to the structure of the cutin polymer. However, the structure and formation of this hydrophobic polyester of glycerol and hydroxy/epoxy fatty acids has not been fully resolved. An apoplastic GDSL-lipase known as CUTIN SYNTHASE1 (CUS1) is required for cutin deposition in tomato (Solanum lycopersicum) fruit exocarp. In vitro, CUS1 catalyzes the self-transesteri...
Commercial cell-based skin regenerative products are highly expensive, carry the risk of rejection and require a long cell culture period to manufacture. This work describes synthesis bilayer films from poly(globalide) (PGl) regenerated cellulose nanofibers (rCNFs) their use as cell-free scaffold support keratinocyte attachment proliferation. The method is simple, eco-friendly (as precursor obt...
Abstract Abundant seawater resources can replace the shortage of freshwater resources. The co-production xylo-oligosaccharides and glucose from sugarcane bagasse by subcritical CO 2 -assisted pretreatment was studied in this paper. We investigated effects conditions temperature, pressure reaction time on yield systems. maximum xylo-oligosaccharide 68.23% obtained at 165 °C/2 MPa/5 min. After fu...
In an effort to better understand the biomass recalcitrance, six natural poplar variants were selected as feedstocks based on previous sugar release analysis. Compositional analysis and physicochemical characterizations of these poplars were performed and the correlations between these physicochemical properties and enzymatic hydrolysis yield were investigated. Gel permeation chromatography (GP...
Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source for sustainable energy production and has the potential to be a valuable substitute. Various pretreatment techniques change the physical and chemical structures of the lignocellulosic biomass and improve the hydrolysis rate. The cost of ethanol production from lignocellulosic material is relatively...
In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...
