Abstract The polydispersity of commercially available kraft lignins (KLs) is one the factors limiting their applications in polymer-based materials. A prerequisite thus to develop lignin fractionation strategies compatible with industrial requirements and restrictions. For this purpose, a solvent-based technique has been addressed. partial solubility KL common solvents compliant sustainable chemistry was studied, results were discussed relation Hansen parameters. Based on screening, solvent...
Abstract Hemicelluloses, a family of heterogeneous polysaccharides with complex molecular structures, constitute fundamental component lignocellulosic biomass. However, the contribution each hemicellulose type to mechanical properties secondary plant cell walls remains elusive. Here we homogeneously incorporate different combinations extracted and purified hemicelluloses (xylans glucomannans) from softwood hardwood species into self-assembled networks during cellulose biosynthesis in...
Summary Pattern‐triggered immunity (PTI) is activated in plants upon recognition by pattern receptors (PRRs) of damage‐ and microbe‐associated molecular patterns (DAMPs MAMPs) derived from or microorganisms, respectively. To understand better the plant mechanisms involved perception carbohydrate‐based structures recognized as DAMPs/MAMPs, we have studied ability mixed‐linked β‐1,3/1,4‐glucans (MLGs), present some microbial cell walls, to trigger immune responses disease resistance plants. A...
Abstract The structure of branched polysaccharides involves a hierarchy levels, from the constituent sugars, then branching pattern, up to macromolecular architecture, and supramolecular organization. Finding causal relations between this complex structure/architecture both (bio)synthetic mechanisms final properties is needed for understanding functionality polysaccharides, which important in fields ranging improved nutrition health through papermaking pharmaceuticals. structural complexity...
The first two-dimensional structural distributions are reported for a hyperbranched polymer, the two dimensions being macromolecular size and individual branch length. 2D native starch, polymer with both short- long-chain branched components (amylopectin amylose), were obtained by fractionation using size-exclusion chromatography combined enzymatic debranching. These show distinct architectures: separate "mountains" corresponding to amylopectin amylose "foothills" assigned hybrid...
Sugarcane bagasse and straw are generated in large volumes as by-products of agro-industrial production. They an emerging valuable resource for the generation hemicellulose-based materials products, since they contain significant quantities xylans (often twice much hardwoods). Heteroxylans (yields ca 20% based on xylose content sugarcane straw) were successfully isolated purified using mild delignification followed by dimethyl sulfoxide (DMSO) extraction. Delignification with peracetic acid...
This study explores the preparation of antioxidant starch food packaging materials by incorporation valuable phenolic compounds extracted from sunflower hulls, which are an abundant by-product industry. The were with aqueous methanol and embedded into films. Their effect on films was investigated in terms activity, optical, thermal, mechanical, barrier properties changes molecular structure. structure affected during thermal processing resulting a decrease molar mass, smaller amylopectin...
Xylan is tightly associated with cellulose and lignin in secondary plant cell walls, contributing to its rigidity structural integrity vascular plants. However, the molecular features nanoscale forces that control interactions among microfibrils, hemicelluloses, are still not well understood. Here, we combine comprehensive mass spectrometric glycan sequencing dynamics simulations elucidate substitution pattern softwood xylans investigate effect of distinct intramolecular motifs on xylan...
Sequential subcritical water extraction of birchwood without delignification reveals the interconnected molecular features hemicellulose and lignin that regulate recalcitrance.
This study showed that rice straw waste is a valuable source for the extraction of water-soluble phenolic compounds can be successfully incorporated into bioactive starch-based films. The major in extract were identified as ferulic, p-coumaric and protocatechuic acid using UHPLC-MS. Homogeneous films with antioxidant properties produced by melt blending compression molding changes physico-chemical evaluated. starch slightly reddish-colored exhibited good in-vitro antiradical scavenging...
Commercial mucin glycoproteins are routinely used as a model to investigate the broad range of important functions mucins fulfill in our bodies, including lubrication, protection against hostile germs, and accommodation healthy microbiome. Moreover, purified increasingly selected building blocks for multifunctional materials, i.e., components hydrogels or coatings. By performing detailed side-by-side comparison commercially available lab-purified variants porcine gastric mucins, we decipher...
SUMMARY Xylan is the most abundant non‐cellulosic polysaccharide in grass cell walls, and it has important structural roles. The name glucuronoarabinoxylan (GAX) used to describe this variable hemicellulose. It a linear backbone of β‐1,4‐xylose (Xyl) residues that may be substituted with α‐1,2‐linked (4‐ O ‐methyl)‐glucuronic acid (GlcA), α‐1,3‐linked arabinofuranose (Ara f ), sometimes acetylation at ‐2 and/or ‐3 positions. role these substitutions remains unclear, although there increasing...
