Abstract
The efforts to produce bioethanol using non-crop raw material are recently developed. Sargassum crassifolium is a promising raw material for biofuel production since containing a high concentration of polysaccharides. Pre-treatment of seaweed at working pressure of 15 Psi, temperature of 121^oC and sulphuric acid concentration of 0.2 M increased the reducing sugars concentration up to 26.68 g/l. The application of cellulase (0.5 g/ml) helped increasing the reducing sugars concentration up to 2.56 times (increasing up to 68.32 g/l). Fermentation using a naturally β-glucosidase producing yeast, Saccharomyces cereviceae (JCM 3012) (0.15 g/ml), produced the final bioethanol
conversion up to 90.99%. The activity of β-glucosidase increased up to 20.39 U/ml during fermentation that assisted the degradation of seaweed.
