In this study, total 19 straw samples from four Brassica species were determined with a diverse cell wall composition and varied biomass enzymatic digestibility under sulfuric acid or lime pretreatment. Correlation analysis was then performed to detect effects of cell wall compositions and wall polymer features (cellulose crystallinity, hemicellulosic monosaccharides and lignin monomers) on rapeseeds biomass digestibility. As a result, coniferyl alcohol (G-lignin) showed a strongly negative effect on biomass saccharification, whereas hemicellulosic monosaccharides (fucose, galactose, arabinose and rhamnose) were positive factors on lignocellulose digestions. Notably, chemical analyses of four typical pairs of samples indicated that hemicellulosic monosaccharides and G-lignin may coordinately influence biomass digestibility in rapeseeds. In addition, Brassica napus with lower lignin content exhibited more efficiency on both biomass enzymatic saccharification and ethanol production, compared with Brassica junjea. Hence, this study has at first time provided a genetic strategy on cell wall modification towards bioenergy rapeseed breeding.

The firmness of the two apple varieties: Idared and Pinova was similar during ripening, while it decreased significantly during 3-month storage only for Idared. Pectin-rich fractions were isolated from apple flesh tissue: water-soluble pectin (WSP), imidazole-soluble pectin (ISP), and hemicellulose-rich fractions: natively acetylated hemicelluloses (LiCl-DMSO), deacetylated hemicelluloses (KOH). It was shown that the degree of acetylation (DAc) of the hemicelluloses fraction (LiCl-DMSO) increased during apple ripening and storage, with higher values for Idared.

There are abundant glycosylated substances such as cellulose, hemicellulose, and phytochemical glycosides in plants, which could be converted into functional chemicals such as monosaccharides, oligosaccharides, and bioactive aglycones by cleavage of glycosidic bonds using glycoside hydrolases (GHs). Among those GHs, β-glucosidase and β-xylosidase are the rate-limiting enzymes for degrading cellulose and hemicellulose, respectively, and can convert a variety of glycosylated substances. These two enzymes play important roles in the high value use of plant resources and have great potential applications.

The agro-industry generates substantial waste, necessitating eco-friendly solutions. This study introduces a novel molecularly imprinted polymer (MIPs) for the selective separation of D-xylose from sugarcane residues. A non-covalent imprinted polymer was synthesized via precipitation and optimized through D-xylose adsorption assays.
