Morphology and Physiology

Naumannella halotolerans is a Gram-positive, non-motile bacterium. It is rod-shaped and can form short chains or occur singly. Like other members of the Propionibacteriaceae family, Naumannella is anaerobic, meaning it thrives in environments devoid of oxygen. However, it is halotolerant, capable of growing in high salt concentrations, a trait that distinguishes it from other closely related genera.

Habitat and Ecology

This bacterium was first isolated from saline soils in Germany. Its ability to tolerate high salinity suggests it is well-adapted to extreme environments, such as salt flats, saline lakes, or coastal soil. Its ecological role in such environments is not entirely understood, but it is likely involved in the degradation of organic matter and may play a role in nutrient cycling in saline ecosystems.
