Production of Bioethanol by Co-Culture of Bacillus Substilis, Gliocladium roseum and Saccharomyces cerevisiae from Sago Waste

Author(s): S. H. Socrates*

Abstract: Biochemical characterization of sago industry waste shows that it is rich in carbohydrates, in more specific it contains 52 % of starch. This work deals with the management of waste for bioethanol production. The co fermentation to produce ethanol was carried out with Bacillus substilis (Bacteria), Gliocladium roseum (Fungus) and Saccharomyces Cerevisiae (Yeast). The results show that the ethanol yield 19.08 g/L was obtained in the co-culture of Bacillus substilis, Gliocladium roseum and Saccharomyces Cerevisiae.
