The Oceanospirillales are an order of Pseudomonadota with ten families.

Description

Bacteria in the ''Oceanospirillales'' are metabolically and morphologically diverse, with some able to grow in the presence of oxygen and others requiring an

halotolerant Halotolerance is the adaptation of living organisms to conditions of high salinity. Halotolerant species tend to live in areas such as hypersaline lakes, coastal dunes, saline deserts, salt marshes, and inland salt seas and springs. Halophiles are ...

halophilic The halophiles, named after the Greek word for "salt-loving", are extremophiles that thrive in high salt concentrations. While most halophiles are classified into the domain Archaea, there are also bacterial halophiles and some eukaryotic species, ...

and require high salt concentrations to grow. While they grow in diverse niches, all ''Oceanospirillales'' derive their energy from the breakdown of various organic products. Bacteria in the ''Oceanospirillales'' are motile except for those in the genus ''Alcanivorax''. Bacteria in the ''Oceanospirillales'' include hydrocarbon-degrading groups such as ''Oleispira antarctica'', ''Thalassolituus oleivorans'', and ''Oleiphilus messinensis'' , which were found in the indigenous microbial community in deep waters after the

History

The order ''Oceanospirillales'' was first described in 2005 in the second edition of Bergey's Manual of Systematic Bacteriology, consisting of six families and with the type genus of '' Oceanospirillum''. In 2007, a seventh family was added with the identification of '' Litoricola lipolytica'' and the creation of its family ''Litoricolaceae''.
