Figure 4From: Structural characterization of alkaline hydrogen peroxide pretreated grasses exhibiting diverse lignin phenotypesCorrelating pyrolytic yields of aromatics to Klason lignin. A comparison of all biomass types for all pretreatment conditions shows that the relationship between (A) aromatic pyrolytic yield versus Klason lignin and (B) the pyrolitic 4-vinylguaiacol as a proxy for cell wall ferulates versus Klason lignin with both normalized to the mass of the untreated sample to indicate the amount of material removed from the cell wall.Back to article page
