Chitosan (CS) aerogels with oriented pore structures exhibit broad application prospects owing to light weight, high porosity, and favorable bioactivity, but the dominating drawback in low mechanical strength greatly hinders their functional advantages. In this study, two types of silk microfibers with similar diameter yet different aspect ratios (1–3 (denoting as SmSF) and 50–100 (denoting as LmSF)) were used as fillers to reinforce CS aerogels prepared by directional freeze casting. The distinction of SmSF and LmSF in size led to their notable variations in distribution pattern, as SmSF embedded within the individual CS lamellae while LmSF traversed throughout the adjacent CS lamellae, which in consequence significantly influence their mechanical reinforcing efficiency. The compressive strength values could be improved from 61.67 kPa (pure CS aerogel) to 82.13 kPa (SmSF/CS aerogel) and 165.03 kPa (LmSF/CS aerogel), respectively, attributing to the transition in deformation mechanisms from a bending- to crumpling-dominated mode. In addition, the embedding or bridging structure could also change the liquid transportation property of CS aerogels. The results of this study demonstrated the feasibility of applying filler-size-mediated strategy for material structural optimization.</div></div>","PeriodicalId":52344,"journal":{"name":"Journal of Bioresources and Bioproducts","volume":"10 2","pages":"Pages 187-198"},"PeriodicalIF":20.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143890747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They include 10,13-epoxy-11-methyl-octadecan-10,12-dienoic acid, which has been identified in the lipid fraction of latex from two <em>Hevea brasiliensis</em> genotypes commonly known as the source of natural rubber. Those two genotypes, namely RRIM501 and PB235, are from Rubber Research Institute of Malaysia (RRIM) and Prang Besar, Malaysia (PB), respectively. This research aimed to undertake the first ever investigation into the existence of this potential high value-added co-product in the lipid fraction of 48 <em>Hevea brasiliensis</em> genotypes, seeking to study the widest possible clonal variability. The results showed furan fatty acid exists in all lipid fractions of their latices. Its content varied significantly, ranging from 0.01% to 0.71% (<em>w</em>/<em>w</em> in latex), the highest concentrations were found in genotypes from the Institut de Recherche sur le Caoutchouc (IRCA) in Côte d'Ivoire, Prang Besar (PB) in Malaysia, and Rubber Research Institute of Vietnam (RRIV) in Vietnam breeding programs. A positive correlation with total fatty acid content was observed when its content exceeded 0.10%, suggesting an additive rather than a substitutive role with the other fatty acids present. Interestingly, linoleic and palmitoleic acids strongly correlated with the furan fatty acid concentration, indicating a possible biosynthetic pathway linkage. In terms of yield per tapping PB235, RRIV4, RRIV2, IRCA41, IRCA18, PB324, IRCA814, IRCA323, and IRCA109 genotypes showed the highest production potential, with yields range of 1 367–2 446 mg furan fatty acid per tree per tapping. Notably, the biochemical markers of natural rubber productivity (sucrose, inorganic phosphorus, thiols, and total solid content) showed no direct involvement in furan fatty acid biosynthesis during latex regeneration between tappings. Based on knowledge of the parentage of the studied clones, a trait heritability study was conducted and genotype PB5/51 was identified as a very worthwhile genitor for improving furan fatty acid contents in a breeding population.</div></div>","PeriodicalId":52344,"journal":{"name":"Journal of Bioresources and Bioproducts","volume":"10 1","pages":"Pages 111-122"},"PeriodicalIF":20.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the accumulation of lignin in high concentrations in the body brings about varying degrees of biotoxicity. Herein, a controlled/sustained release polyvinyl alcohol/chitosan/sulfonated lignin hydrogel (PVA-CS-L) integrated mechanical strengthening and bioactivities of lignin was developed. The lignin-induced non-covalent bond network (van der Waals force, hydrogen and electrostatic interactions) promoted energy dissipation when the hydrogel was subjected to stretching and compression. This endowed the PVA-CS-L hydrogel with improved tensile (∼36 kPa) and compressive strength (∼900 kPa), as well as compressive toughness (∼9.0 MJ/m³), which were superior to the polyvinyl alcohol/chitosan hydrogel (PVA-CS) (31 kPa, 680 kPa, and 7.5 MJ/m³, respectively). The construction of electrostatic interaction could not only slow down the sudden release of lignin but also make the hydrogel exhibit a good pH-sensitive behavior of controlled-release lignin. Also, the developed hydrogel had good biocompatibility and the released lignin had reactive oxygen species scavenging as well as inhibitory activity against <em>Staphylococcus aureus</em>. Finally, preliminary evaluation of drug delivery reveals that the presence of lignin enabled the hydrogel to exhibit longer-lasting controlled/sustained epigallocatechin gallate release properties.

In this review, we summarize recent developments in the use of biomass materials to engineer macroporous tissue engineering scaffolds. We highlight key techniques, such as microparticles assembly, leaching template, and bioprinting that can create macropores within scaffolds composed of biomass materials and their composites.
