(f) Zymomonas mobilis
Spoilage by Zymomonas is unknown in beer, but though uncommon, is often considered the most serious form of spoilage in ale-type beer. Infection with can lead to total and prolonged loss of production and the economic con sequences have forced the closure of at least one brewery. Zymo monas is a facultative anaerobe, although some strains are unable to grow aerobically. The organism is unusual in that glucose is fer. mented anaerobically via the Entner-Doudoroff pathway. Zymo- monas is related phenotypically, genetically and ecologically to the acetic acid bacteria and may be derived from a common aerobic ancestor. Zymomonas mobilis has two sub-species, but only one Z mobilis ssp. mobilis, is a problem in beer
