This research was carried out in the National Commission for Biotechnology in Syria, during 2011- 2013. The aim of this research was to study to effect of some growth parameters on production of ethanol using LMG 404 strain of Zymomonas mobilis bacteria, which was imported from Belgium. Four levels of temperature (25, 30, 35 and 40° C), and pH values (6, 6.5, 7 and 7.5), and Brix% (16, 20, 24 and 28) were studied on the ability of this strain to produce ethanol from sugar beet molasses. The results showed that the highest ethanol production was at 30º C, pH=6.5, and Brix=16%.
Key words: Molasses, Fermentation, Ethanol, Zymomonas mobilis.
