Unit ratio of the associated lignin in the untreated and biopretreated cellulosic samples (the subscript X represents the different incubation weeks). A 1N NaOH (ester-bound phenolics); B 4N NaOH (ether-bound phenolics); C alkaline nitrobenzene oxidation (non-condensed phenolics). (S represents the total mass of syringaldehyde, syringic acid and acetosyringone; V represents the total mass of vanillin, vanillic acid and acetovanillone; H represents the total mass of p-hydroxybenzoic acid and p-hydroxybenzaldehyde).
