| Abstract: | This
study presents ethanol production from enzymatically hydrolyzed sugarcane
bagasse using Saccharomyces cerevisiae.Response
surface methodology (RSM) was used to optimize conditions for the production of
endo b-1, 4 glucanase component of cellulase using Aspergillus
nidulans MTCC344 under solid state condition,
employing pretreated bagasse as chief substrate. Cellulase thus produced was
utilized for hydrolyses of pretreated bagasse resulting in soluble sugars. FTIR
and XRD of bagasse
showed
structural changes through pretreatment, in favor of enzymatic hydrolysis
during cellulase production. Ethanol produced was found to be strongly
dependent on pretreatment given, hydrolysis and fermentation conditions. |
