Marinoida

Marinoida is a genus of marine bacteria belonging to the family Marinomonadaceae. These bacteria are typically Gram-negative and rod-shaped, often observed as motile by means of a single polar flagellum. They are commonly found in marine environments, including seawater, sediment, and associated with marine organisms such as algae and invertebrates.

Members of the genus Marinoida are generally aerobic, requiring oxygen for respiration, and are chemoorganotrophic, meaning they derive energy from organic compounds. Their metabolic capabilities can vary, but many species are known to be capable of degrading complex organic matter present in their marine habitats. This characteristic suggests a role in nutrient cycling within these ecosystems.

The taxonomy of Marinoida has been established through phylogenetic analysis, primarily based on 16S rRNA gene sequences. Several species have been described and formally named within the genus, each with specific physiological and genetic characteristics. Research into Marinoida contributes to our understanding of marine microbial diversity and the ecological functions performed by bacteria in ocean environments.
