VG pretreated and enzyme hydrolyzed were analysis of surface area and morphology by SEM. Fig. 1 show the SEM of untreated VG, 1% NaOH, 0.5% H2SO4 and 10-fold of enzyme. This 1% NaOH to removal of lignin and modification of VG fiber show in Fig. 1(b). The preatreated VG with 1% NaOH -0.5% H2SO4 to swelling show in Fig. 1(C) moreover, H2SO4 to removal of hemicellulose, the show the easily for enzymatic hydrolysis. Fig. 1(d) show the hydrolyzed with 10-fold of Cellic®CTec 2. This figure
