👉 Johnstonella is a gram-positive, rod-shaped bacterium that belongs to the family of Enterobacteriaceae and is commonly found in soil and water bodies. It primarily lives as a commensal in soil ecosystems, where it can be present in association with other bacteria or fungi. Its ability to adapt to different environments and survive under extreme conditions makes it an important part of the natural history of soils and aquatic ecosystems.
