Fermentation of sugar to ethanol and  can also be done by Zymomonas mobilis, however the path is slightly different since formation of pyruvate does not happen by glycolysis but instead by the Entner–Doudoroff pathway.
Other microorganisms can produce ethanol from sugars by fermentation but often only as a side product. Examples are
* Heterolactic acid fermentation in which Leuconostoc bacteria produce lactate + ethanol + 
* Mixed acid fermentation where Escherichia produce ethanol mixed with lactate, acetate, succinate, formate, , and H
* 2,3-butanediol fermentation by Enterobacter producing ethanol, butanediol, lactate, formate, , and H
