Conclusions
The results showed that ethanol production from mahula flowers
by S. cerevisiae was 21.2% higher in comparison to Z. mobilis. For
both the microorganisms, the peak ethanol concentration was obtained
after 96 h of fermentation. Despite many efforts undertaken
world wide, Zymomonas has not yet been commercialized for
ethanol production due to its low tolerance to temperature, ethanol
and utilization of limited substrate range, as evident from the
present study.
