Pectin is a minor wall polysaccharide with potential applications for bioproducts. Despite the application of specific plants and biomass-based sorbents for environmental remediation, little has been reported about characteristic roles of pectin. Using the natural rice mutant (Osfc16) treated with Cd, this study explored that pectin could predominately enhance Cd accumulation with lignocellulose, mainly due to remarkably raised uronic acids deposition. The Cd-treatment further reduced lignocellulose recalcitrance for significantly enhanced biomass saccharification and bioethanol production along with almost complete Cd release. Using all remaining fermentation rice residues that are of typical ribbon-structure and large surface, this study generated novel biosorbents by optimal chemical oxidation with the pectin extraction from citrus peels, and examined consistently raised Cd and methylene blue (MB) adsorption capacities. Therefore, this work has proposed a mechanism model about multiple pectin enrichment roles for Cd and MB removals in agricultural and industry locations with full lignocellulose utilization towards bioethanol production.

对果胶的洞察力在消除有毒镉和染料方面占主导地位,同时在理想的木质纤维素中产生乙醇
果胶是一种具有潜在应用的生物制品的小壁多糖。尽管特定植物和基于生物质的吸附剂用于环境修复,但关于果胶的特征作用的报道很少。使用天然水稻突变体(Osfc16) 用 Cd 处理,本研究探讨了果胶可以主要增强 Cd 与木质纤维素的积累,主要是由于糖醛酸沉积显着增加。Cd 处理进一步降低了木质纤维素的顽固性,显着增强了生物质糖化和生物乙醇的生产,同时几乎完全释放了 Cd。本研究利用所有剩余的具有典型带状结构和大表面的发酵米残渣,通过从柑橘皮中提取的果胶进行优化化学氧化,生成了新型生物吸附剂,并检测了持续提高的 Cd 和亚甲蓝 (MB) 吸附能力。所以,
