Summary Cassava and sago starch were evaluated for their feasibilities as substrates for ethanol production using Zymomonas mobilis ZM4 strain. Before fermentation, the starch materials were pretreated employing two commercial enzymes, Termamyl (thermostable α-amylase) and AMG (amyloglucosidase). Using 2 μl/g of Termamyl and 4 μl/g of AMG, effective conversion of both cassava and sago starch into glucose was found with substrate concentration up to 30%(w/v) dry substances. Fermentation study performed using these starch hydrolysates as substrates resulted in ethanol yield at an average of 0.48g/g by Z. Mobilis ZM4.
