Phenolic compounds in hydrolysate generated by flowthrough and batch pretreatment of cellulolytic enzyme lignin. Cumulative release of phenolic compounds from flowthrough pretreatment (20 mL/min) are plotted as a function of time: (a) 140°C, 12 minutes; (b) 140°C, 192 minutes; (c) 180°C, 12 minutes; (d) 180°C, 192 minutes. Distribution of primary phenolic compounds after batch pretreatment: (e) at 140°C for 192 min and (f) at 180°C for 12 min.
