Abstract
The study examined the impact of high temperature chemical prehydrolysis methods: acid (H2SO4 and HCl) and alkali (NaOH) on ethanol yield of sweet sorghum plant. After prehydrolysis samples ware hydrolyzed enzymatically (ACCELLERASE®1500 and ACCELLERASE®XC) and subjected to ethanol fermentation with yeast Saccharomyces cerevisiae SIHA Active Yeast 6. The highest ethanol yield (77.8 cm3 kg-1) of sweet sorghum biomass was obtained, applicable for the pretreatment 2% sulfuric acid (IV) at 150°C. However, in the case of lower prehydrolysis temperatures (121, 134°C) preferred seems to be sodium hydroxide at 6 or 10% use.
