  1. 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
  2. bThe “Temp.” represents the abbreviation of temperature; the severity factors (logR0) for all pretreatments were calculated by the Eq. (3)
  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
  4. dThe component removal is calculated by the Eq. (2)
  5. eThe data represent the sum of the contents of xylan, mannan, and galactan in untreated Masson pine and the LHW-pretreated substrate
