Fig. 1From: Inhibition of lignin-derived phenolic compounds to cellulaseEffect of vanillin concentration on enzymatic hydrolysis (a) and apparent inhibition degrees (b) during cellulose conversion. Cellulose loading was 1 % (10 mg/mL) and cellulase concentration was 0.3 mg/mL. Error bars represented standard deviations, n = 3Back to article page
