ResumoAbstract Ethanol production from fresh tubers, flour and starch of tapioca was studied by simultaneous saccharification and fermentation procedure. A 20% enzyme‐liquefied slurry showed about 2–3% reducing sugars, which increased to 10% on enzymic saccharification for 4h. Alcoholic fermentation of this hydrolysate with Saccharomyces cerevisiae , Var. ellipsoideus , yielded 8–9% alcohol showing about 95% fermentation efficiency. Large scale fermentation of tapioca flour by this process also showed fermentation efficiency of 90% thereby indicating the economic viability of the process.
