Abstract |
Cassava pulp, a solid by-product from cassava starch processing, is a promising and underused biomass that can be converted into biofuels and other value-added products. The aim of this research was to produce ethanol from cassava pulp through pre-hydrolysis and simultaneous saccharification and fermentation (PSSF) using α-amylase, glucoamylase, and cells of Saccharomyces cerevisiae TISTR 5339 immobilized on bacterial cellulose. The ratio between α-amylase and glucoamylase, as well as the concentration of cassava pulp were optimized before use in the PSSF process. Results showed that the optimum ratio was 75:25 on a wet mass basis, and the optimum cassava pulp concentration was 60 g/L. Pre-hydrolyzing 200 mL of 60 g/L of cassava pulp at 50°C for 2 h using 10% (w/v) of the mixed enzymes at 75:25 ratio, followed by simultaneous saccharification and fermentation (SSF) at 30°C using 10% (w/v) of immobilized S. cerevisiae cells gave 18.2±0.69 g/L of ethanol, with a productivity of 0.15 g/(L h) and a fermentation efficiency was 63.93%. |
