This investigation aimed at the production of bioethanol in the laboratory scale by undergoing co-culture fermentation in the presence of fungus, Aspergillus niger (AN106) and yeast, Saccharomyces cereviseae using cassava starch as the main substrate. The production of ethanol by direct bioconversion of cassava recorded to 7-9% (v/v).
