The current study aimed to obtain fermentable sugars from canola waste feedstocks cultivated different harvests by SWH. The processing conditions were temperature of 230 °C, water/solids mass ratios of 4 and 8 g water/g feedstock, and reaction time of 60–1800 s. For H433 silique 2019 and H575 stalk 2020, the highest fermentable sugar yields were obtained, resulting in 10.2 g/100 g silique and 11.5 g/100 g stalk, respectively. For all stalk and silique biomasses, xylose and cellobiose presented a high content. Organic acid yield was higher for DH canola silique (16.22 g/100 g silique). Accordingly, this study pioneered the exploration of the potential of canola lignocellulosic materials to produce fermentable sugars, which can be broadly encouraging when applied in the bioethanol industry.

油菜原料通过亚临界水水解生产可发酵糖的潜力

目前的研究旨在从通过 SWH 培养的不同收成的油菜废料原料中获得可发酵糖。处理条件是温度为 230 °C,水/固体质量比为 4 和 8 g 水/g 原料,反应时间为 60-1800 s。对于 H433 长角果 2019 和 H575 茎秆 2020,获得了最高的可发酵糖产量,分别产生 10.2 克/100 克长角果和 11.5 克/100 克茎秆。对于所有茎秆和长角果生物质,木糖和纤维二糖含量较高。DH canola sillique (16.22 g/100 g sillique) 的有机酸产率较高。因此,这项研究开创了探索油菜木质纤维素材料生产可发酵糖的潜力,这在应用于生物乙醇行业时可以得到广泛的鼓舞。
