The current study aimed to obtain fermentable sugars from canola waste feedstocks. High yields of fermentable sugars were obtained by processing the waste with SWH method, showing potential application in the bioethanol industry.
The current study aimed to obtain fermentable sugars from canola waste feedstocks cultivated different harvests by SWH. The processing conditions were temperature of 230 degrees 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.
