“…However, they mostly focused on the effects of the pretreatment on the enzyme susceptibility of the solid residues resulted from pretreatment. On the other hand, reports on the production of xylose from the biomass were mostly used inorganic acids, such as sulfuric, hydrochloric, and nitric acids and combined with conventional heating (Ahmed et al, 2001, de Paiva et al, 2009, Rahman et al, 2007, Rocha et al, 2014, Ji et al, 2017, Krishania et al, 2018. The use of microwave and organic for producing xylooligosaccharides from beechwood xylan and corncob hemicellulose with xylose as by product has been reported by Lin et al (2017).…”
