Moritellaceae

Moritellaceae is a family of Gram-negative, facultatively anaerobic bacteria belonging to the order Vibrionales. The type genus of this family is Moritella. Members of Moritellaceae are typically rod-shaped and motile. They are characterized by their ability to grow under psychrophilic conditions, meaning they thrive in cold environments.

The genus Moritella was first described in 1998. Several species have been identified, primarily isolated from marine environments. These include *Moritella marina*, *Moritella aenigmatica*, and *Moritella profunda*. They are often found in association with marine animals, such as fish and invertebrates, and can be isolated from deep-sea sediments and hydrothermal vents.

Physiologically, Moritellaceae are known for their cold-adaptation mechanisms, which allow them to maintain membrane fluidity and enzyme activity at low temperatures. They are chemoheterotrophic, utilizing organic compounds for energy and carbon. While generally considered non-pathogenic, their presence in marine food webs and potential involvement in the spoilage of seafood are areas of interest. Further research is ongoing to fully understand their ecological roles and metabolic capabilities.
