Acetobacter estuniensis

Genus/species: Acetobacter estuniensis

Gram Stain: Negative

Morphology:

  • Cell: ellipsoid or rod-shaped
  • Colony:
  • Liquid Growth: dispersed

Physiological Traits: 
Carbon sources are glucose, ethanol, mannitol; produce acetic acid; requires oxygen for growth but may be able to use other reducible compound as electron acceptors to survive partial anaerobiosis; organic acids may be possible oxidation substrates.
