A new method was proposed which allowed more accurate crystallinity results for lignocellulose comparing to conventional calculation models. The is based on the estimation of changing rate XRD intensity I = f(2θ) over entire range scattering angles. Pure crystalline and amorphous cellulose were used as calibration samples, since can be easily determined by 13C CP/MAS NMR. successfully applied three types plant biomass model mixtures, such a mixture birch xylem with micro cellulose, alkaline...
Kraft pulp enzymatic hydrolysis is a promising method of woody biomass bioconversion. The influence composition and structure kraft fibers on their efficiency was evaluated while using four substrates, unbleached hardwood (UHP), softwood (USP), bleached (BHP), (BSP). Hydrolysis carried out with Penicillium verruculosum enzyme complex at dosage 10 filter paper units (FPU)/g pulp. changes in fiber morphology were visualized optical electron microscopy. Fiber cutting swelling quick xylan...
The global development of the bioeconomy is impossible without technologies for comprehensive processing plant renewable resources. use proven pretreatment raises possibility industrial implementation enzymatic conversion polysaccharides from lignocellulose considering process’s complexity. For instance, a well-tuned kraft pulping produces substrate easily degraded by cellulases and hemicelulases. Enzymatic hydrolysis bleached hardwood pulp was carried out using an enzyme complex...
Polysaccharide-based cryogels are promising materials for producing scaffolds in tissue engineering. In this work, we obtained ultralight (0.046–0.162 g/cm3) and highly porous (88.2–96.7%) with a complex hierarchical morphology by dissolving cellulose phosphoric acid, subsequent regeneration freeze-drying. The effect of the dissolution temperature on acid freezing time hydrogels structure properties were studied. It has been shown that prolonged leads to formation denser stronger network...
Cryogelation is a developing technique for the production of polysaccharide materials biomedical applications. The formation macroporous structure during freeze-drying solutions creates biomaterials suitable tissue engineering. Due to its availability, biocompatibility, biodegradability, and non-toxicity, chitin promising natural porous engineering; however, use limited due difficulty dissolving it. This work describes preparation cryogels using phosphoric acid as solvent. Compared typical...
The efficiency of biocatalysts based on a cellulase complex obtained using the fungus Penicillium verruculosum in hydrolysis kraft pulp softwood and hardwood timber was studied. activity toward unbleached bleached dependence conversion cellulose content non-cellulosic components were determined. It is shown that wet highly reactive enzymatic by from P.verruculosum great interest as substrate when scaling biotechnological processes bioconversion renewable raw materials.
Abstract Silver nanoparticles (AgNP) were obtained by reduction of silver ions in alkaline solutions polygalacturonic acid (PGA), the main chain pectins. The growth AgNP during reaction was monitored UV/Vis spectroscopy. PGA containing AgNPs nanoprecipitated into an anti-solvent (ethanol) bath. Spherical particles ca. 70 nm observed atomic force microscopy embedded spherical registered transmission electron (TEM) and scanning (SEM) microscopies. AgNP’s distribution determined both TEM SEM...
