Da Silva et al. reported that planetary ball milling was more effective for sugar cane bagasse than straw, whereas wet disk milling was more appropriate for the pretreatment of sugar cane straw than bagasse, in terms of the glucose and xylose yields [43, 53]. This might be due to the difference in composition and structural arrangements …
