A study was carried out on the role of different trace element on the production of Bioethanol by an ethanol resistant strain Saccharomyces cerevisiae AB810 for the selection of suitable medium. It was observed that Zn2+, Mn2+ and Fe3+ were required for this ethanol resistant strain. The optimum levels of Zn2+ 5 μg/ml, Mn2+ 10 μg/ml and Fe3+ 15μg/ml were required for the maximum production of Bioethanol. But other elements mainly Cu2+, Ni2+, Co2+, Fe2+ and Mo6+ had an adverse effect on Bioethanol production by this strain. Thus, addition of necessary trace element into the fermentation medium resulted significant (p<0.001)increase in Bioethanol production of 16.6% compared to the production of Bioethanol before addition of necessary trace elements into the fermentation medium(12.0%).
