Figure 2From: Optimization of NaOH-catalyzed steam pretreatment of empty fruit bunchTime course of SSF of NaOH-soaked EFB (10% w/w) pretreated under different conditions: (a) 1.5% NaOH, 160°C, 10 min; (b) 3.0% NaOH, 160°C, 10 min; (c) 3.0% NaOH, 160°C, 11 min 20 sec. The SSF was performed with 40 FPU of Cellic CTec2/g glucan at 30°C and 200 rpm for 36 h in a 500 ml flask.Back to article page
