Commercial Scale Quantification of Lignin
Abstract: Lignin, an aromatic biopolymer, in the terrestrial lignocellulosic biomass constitutes the single largest and sustainable source of biofuels and biochemicals. The recalcitrant nature of lignin is a hindrance to its chemical or biochemical conversion. Moreover, its insolubility in water too is a major challenge in its quantification which is a necessary step prior to and after its conversion. Though there are celebrated quantification methods like the classical Klason lignin method …
