ABSTRACT
The global population and industrialization have increased energy demand. This study focused on biobutanol production for biofuels and other high-value products. This study compares corn cob and cassava bagasse biobutanol production. Due to their estimated hemicellulose, cellulose, and lignin content, corn cob and cassava bagasse, both waste products, are suitable biobutanol feedstocks. Lab analysis did this. Dilute sulfuric acid and enzymatic hydrolysis produced fermentable sugar. The response surface methodology was used to optimize the sulfuric pretreatment's concentration, temperature, and time. This was done to recover lots of fermentable sugars from both feedstocks. At 760C, 31 minutes, and 4.3% (w/w) hydrogen sulfide, total sugars in corn cob and cassava bagasse showed their highest response, which was 804.23 mg/L and 807.28 mg/L, respectively. Enzymatic hydrolysis using cellulase and betaglucosidase enzymes was performed under these conditions. Within the first 24 hours after hydrolysis, there was an overall increase of 15% in the total sugars. Because of the findings of this research, it is possible to draw the conclusion that corncob bagasse and cassava bagasse are two excellent and environmentally friendly feedstock options for the production of biobutanol.
