Question

Quizplus · Accepted Answer

A gram-negative rod that ferments sugars to ethanol is characteristic of the genus Zymomonas. The fact that it is polar flagellated further supports this identification. Gluconobacter and Acetobacter are both gram-negative bacteria that oxidize ethanol to acetic acid, while Vibrio is a curved, gram-negative rod that is not known for fermenting sugars to produce ethanol.
