Abstract: The conversion of starch from unhydrolyzed cassava flour to ethanol by a pure culture of Endomycopsis fibdigera and by a co-culture of this amylolytic yeast and the bacterium Zymmonas mobilis was studied.The best overall results were obtained using the mixed culture. After 96 h of fermentation of a medium containing 150 g/l initial cassava starch, an ethanol concentration of 31.4 g/l, a productivity of 0.33 g ethanoyl x h and a yield of 0.21 g ethanoyg initial starch were reached. The highest yield (0.37 g/g)…
