They are rod-shaped bacteria that are straight or curved. The Gram stain is negative. Many species are motile by polar flagella , some are immobile. They usually occur individually, but pairs or short chains also occur. They do not form endospores or microcysts .
Growth and metabolism
All representatives are chemo-organotrophic , photosynthesis is not carried out. They are facultatively anaerobic , so they can live in the presence or absence of oxygen and use fermentation to generate energy. When oxygen is present, aerobic breathing is performed. Most species are oxidase- positive and use glucose as a metabolic substrate . They reduce nitrate to nitrite . Many species use ammonium salts as the sole source of nitrogen. Oceanimonas needs NaCl . The representatives of the family tolerate a relatively wide range of temperatures for growth, there are both mesophilic and psychrophilic species.
Some types of Aeromonas are among the spoilage agents in food, as these types are psychrophilic (cold-loving), they can also spoil cold storage goods . The species of Aeromonas pathogenic to humans include e.g. B. Aeromonas punctata subsp. caviae and Aeromonas hydrophila . Aeromonas hydrophila can also cause disease in fish, but is primarily known as a pathogen in frogs.
The family of the Aeromonadaceae forms together with the family of the Succinivibrionaceae the order of the Aeromonadales , this is in the class of the Gammaproteobacteria. Aeromonas is the type genus of the family and the order. The family includes the following genera (as of January 24, 2019):
