The Oceanospirillales are an order of Pseudomonadota with ten families. [2]
Bacteria in the Oceanospirillales are metabolically and morphologically diverse, with some able to grow in the presence of oxygen and others requiring an anaerobic environment. [3] Members of the Oceanospirillales can be halotolerant or halophilic and require high salt concentrations to grow. [3] 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. [3] 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 Deepwater Horizon oil spill in 2010. [4] They are also common members of bacterial communities in the water column of the hadal zone of ocean trenches. [5]
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 . [6] In 2007, a seventh family was added with the identification of Litoricola lipolytica and the creation of its family Litoricolaceae. [2] [7]
The Hyphomicrobiales are an order of Gram-negative Alphaproteobacteria.
The Comamonadaceae are a family of the Betaproteobacteria. Like all Pseudomonadota, they are Gram-negative. They are aerobic and most of the species are motile via flagella. The cells are curved rod-shaped.
Oceanospirillaceae is a family of Pseudomonadota. Most genera in this family live in environments with high concentrations of salt; they are halotolerant or halophilic. They are marine, except Balneatrix which is found in fresh water and Venatorbacter, which is from terrestrial origin.All members are strictly aerobic, except Neptunomonas which can perform fermentation reactions.
The Ectothiorhodospiraceae are a family of purple sulfur bacteria, distinguished by producing sulfur globules outside of their cells. The cells are rod-shaped, vibrioid, or spirilla, and they are able to move using flagella. In general, they are marine and prefer anaerobic conditions. Ectothiorhodospiraceae are a vibrio bacteria that require salty living conditions to survive and grow: classifying them as slightly halophilic. Like all purple sulfur bacteria, they are capable of photosynthesis. To complete this energy process, Sulfur compounds are used as electron donors for carbon fixation in the pentose phosphate pathway. This elemental sulfur accumulates outside of the cells.
Slackia is a genus of Actinomycetota, in the family Coriobacteriaceae. Slackia is named after the microbiologist Geoffrey Slack.
The Myxococcota are a phylum of bacteria known as the fruiting gliding bacteria. All species of this group are Gram-negative. They are predominantly aerobic genera that release myxospores in unfavorable environments.
In the taxonomy of microorganisms, the Methanomicrobia are a class of the Euryarchaeota.
The Bacteroidaceae are a family of environmental gram-negative bacteria commonly found in the human gut microbiota.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
Caldanaerobacter is a Gram-positive or negative and strictly anaerobic genus of bacteria from the family of Thermoanaerobacteraceae.
Caldanaerobius is a genus of thermophilic, obligately anaerobic bacteria from the family of Thermoanaerobacteraceae.
Carboxydothermus is a genus of thermophilic, anaerobic bacteria from the family of Thermoanaerobacteraceae.
Desulfonatronovibrio is a Gram-negative, vibrios, anaerobic and motile genus of bacteria from the family of Desulfohalobiaceae with a single polar flagellum.
Conexibacter is a Gram-positive, non-spore-forming and aerobic genus of bacteria from the family Conexibacteraceae.
Solirubrobacter is a Gram-positive, spore-forming, aerobic, mesophilic and non-motile genus of bacteria from the family Solirubrobacteraceae.
Oribacterium is a strictly anaerobic and non-spore-forming bacterial genus from the family of Lachnospiraceae.
Frondihabitans is a Gram-positive, non-spore-forming and non-motil genus of bacteria from the family of Microbacteriaceae.
Heliorestis is an alkaliphilic genus of bacteria from the family of Heliobacteriaceae.
The Dermatophilaceae is a Gram-positive family of bacteria placed within the order of Actinomycetales. Dermatophilaceae bacteria occur on animal and human skin and in fish guts.
Phycisphaeraceae is a family of bacteria.
