Isolation from beer of a sucrose‐fermenting species of Zymomonas confirmed as Z. mobilis , is recorded. Motility and H 2 S production were variable and sensitive to precise environmental conditions. The beer‐spoilage potential of this species was established as limited. A strain of Z. anaerobia was isolated which acquired sucrose‐fermenting ability after growth in fructose. It is doubtful, therefore, whether the creation of two distinct species within this genus is valid.
