^aThe numbers after T and t stand for the pretreatment temperature (°C) and duration (min); B, E, P, SSR and K refer to the abbreviations of bamboo, eucalyptus, Masson pine, solid substrate recovery and Klason, respectively

^bThe “Temp.” represents the abbreviation of temperature; the severity factors (logR₀) for all pretreatments were calculated by the Eq. (3)

^cThe data before and after slashes (/) are the component content based on the o.d. the weight of raw materials and pretreated substrates, respectively

^dThe component removal is calculated by the Eq. (2)

^eThe data represent the sum of the contents of xylan, mannan, and galactan in untreated Masson pine and the LHW-pretreated substrate
