Fig. 4From: Limitation of cellulose accessibility and unproductive binding of cellulases by pretreated sugarcane bagasse ligninCorrelation between PSCB cellulose hydrolysis yields after 72 h with Celluclast and Novozym 188 and the accessible cellulose surface. NaOH PSCB (orange), H2SO4 PSCB (red), NaHSO3/H2SO4 PSCB (green), SO2/steam PSCB (black), and Na2SO3/NaOH PSCB (blue). Enzyme loadings were 2.5, 5, 10, 20, and 30 mg/gBack to article page
