摘要：
The present study was carried out to assess bioethanol production from waste potatoes and optimize some fermentation variables for Zymomonas mobilis MTCC 2427. The waste potatoes contained 76% starch. Under solid state fermentation (SSF) maximum bioethanol of 14.17 g 100 mL(-1) medium was achieved at 35 degrees C when incubated for 120 hr. Under simultaneous saccharification and fermentation (SiSF), highest ethanol yield of 14.36 g 100 mL(-1) medium was attained at 35 degrees C, pH 5.5 and 120 hr. The ethanol produced was volatile, flammable, colourless and miscible in water and organic solvents having pleasant smell. SiSF fermentation gave more ethanol recovery than SSF method.
