Figure 2From: Biorefining of wheat straw: accounting for the distribution of mineral elements in pretreated biomass by an extended pretreatment-severity equationRecovery of glucose, lignin, silicon (Si), and ash in the washed fiber fraction of hydrothermal pretreated wheat straw (weight base, dry matter). No dependency of the pretreatment conditions were observed by multiple linear regression (whole model P > 0.05).Back to article page
