Bioethanol Production Using Simultaneous Saccharification and Fermentation Method
Keywords:
Bioethanol, Rhizopus sp, Saccharomyces cerevisiae IR2, Tuber crops, Simultaneous Saccharification and Fermentation MethodsAbstract
Bioethanol, an alcohol produced by fermentation of plant biomass containing carbohydrates by micro-organisms is considered a dominant form of fuel for future. Production of this renewable fuel, especially from starchy materials such as tuber/energy crops, and cereal holds a remarkable potential to meet the future energy demand because of its potential for high productivity. However, this potential can only be realized by selecting appropriate feedstock and production system. This study focused on comparison of bioethanol productivities from tuber/energy crops such as cassava, sweet potato, yam, cocoyam and (cereal) maize using the co-cultures of Rhizopus sp and Saccharomyces cerevisiae IR2 in simultaneous saccharification and fermentation method. Gelatinized sweet potato and cocoyam flours using solid state cultures (koji) gave the highest bioethanol production of 2.29 % (v/v). The gelatinization of flours resulted in increased ethanol production compared to raw flours.
