    Bioethanol is one of the leading alternative biofuel to fossil fuels and can be use in
    existing gasoline engines without any major modification. Bioethanol can be
    produced from sugar containing biomass fermentation using different potential
    strains. In this study, the gram negative, facultative anaerobic, rod shaped strain
    ‘Zymomonas mobilis’ was used as microorganism to produce bioethanol from sugar
    cane molasses using anaerobic fermentation. The study was conducted to investigate
    the optimized conditions for production of bioethanol through batch fermentation
    process. The fermentation unit was designed to determine the effect of process
    parameters such as fermentation temperature, pH, sugar concentration and supply of
    nutrients. The Zymomonas mobilis produced 9.3% (v/v) bioethanol by utilizing 16
    g/100mL sugar with the fermentation efficiency 92.5%. The fertilized based nutrients
    were supplied to enhance the production of bioethanol yield. The bioethanol yield
    produced by using this strain in optimized conditions is in good compromise with
    previous study and also compared with commercially available yeast strain.
