for this study. Enzymatic hydrolysis of pretreated EFB fibers was conducted in accordance with the standard National Renewable Energy Laboratory (NREL) procedure for chemical analysis and testing [14]. Operating conditions were 50 °C, pH 4.8 (controlled using sulfuric acid), and agitation at 60 Hz. The enzyme loading amounts were 40 FPU/g cellulose (Cellic® CTec 2) and 15% Cellic® HTec 2 (this value was based on the amount of Cellic® CTec 2 loaded into the mixture). Enzymatic hydrolysis was performed once two batches of the pretreated mixture were collected. After saccharification, the sample was transferred to the fermentation tanks and fermented with 5% Saccharomyces cerevisiae at 33 °C for 48 h.
