Abstract

Arundo donax was used to investigate the effect of enzyme and substrate concentration on hydrolysis, pre-hydrolysis and simultaneous saccharification and fermentation (PSSF) and simultaneous saccharification and fermentation (SSF). Hydrolysis was performed at 37 and 50 °C. At the highest biomass (10%) and enzyme (69.63 FPU g-1 cellulose) loading, the highest glucose concentration (32.35 g L-1) was obtained (at 50 °C). SSF resulted in a cellulose conversion (91.93%) and an ethanol concentration (19.77 g L-1) higher than those obtained using PSSF with pre-hydrolysis at 37 °C (86.86%; 18.78 g L-1) and PSSF with pre-hydrolysis at 50 °C (81.62%; 17.66 g L-1). A positive correlation between cellulase concentration, cellulose conversion and ethanol content was observed. In PSSF, the increase in solid loadings caused a reduction in the theoretical ethanol yield, but the ethanol concentration in PSSF and SSF increased. SSF appears to be an advantageous strategy for bioethanol production from Arundo donax.
