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.
The Oceanospirillales are an order of Pseudomonadota with ten families.
The Chromatiaceae are one of the two families of purple sulfur bacteria, together with the Ectothiorhodospiraceae. They belong to the order Chromatiales of the class Gammaproteobacteria, which is composed by unicellular Gram-negative organisms. Most of the species are photolithoautotrophs and conduct an anoxygenic photosynthesis, but there are also representatives capable of growing under dark and/or microaerobic conditions as either chemolithoautotrophs or chemoorganoheterotrophs.
Slackia is a genus of Actinomycetota, in the family Coriobacteriaceae. Slackia is named after the microbiologist Geoffrey Slack.
Bacteroidales is an order of bacteria. Notably it includes the genera Prevotella and Bacteroides, which are commonly found in the human gut microbiota.
The Bacteroidaceae are a family of environmental gram-negative bacteria commonly found in the human gut microbiota.
The Oceanimonas are a genus of marine bacteria. They are, like all Proteobacteria, gram-negative. The rod-shaped, motile organisms are aerobic and chemoorganotroph.
Chromatium is a genus of photoautotrophic Gram-negative bacteria which are found in water. The cells are straight rod-shaped or slightly curved. They belong to the purple sulfur bacteria and oxidize sulfide to produce sulfur which is deposited in intracellular granules of the cytoplasm.
Chromatium okenii is a Gram-negative bacterium found in water. It belongs to the Purple sulfur bacteria. These bacteria are capable of photosynthesis and use Hydrogen sulfide (H2S) as an electron donor for CO2 reduction and so do not produce oxygen. This type of photosynthesis is called anoxygenic photosynthesis. Chromatium okenii is anaerobic and the cells are slightly curved or straight rods.
Hyphomonadaceae are a family of bacteria in the order Caulobacterales.
Tolumonas is a genus of Gram-negative bacteria. It grows under aerobic and anaerobic conditions and is nonmotile. The cells are rods and occur in pairs or singly. It is known for one of its species biological bacterial production of toluene from phenylalanine and other phenyl precursors
Ilumatobacter is a genus from the order Acidimicrobiales.
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.
Patulibacter is a genus of bacteria from the family Patulibacteraceae.
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.
Thiorhodospira is a genus of bacteria from the family of Ectothiorhodospiraceae with one known species.
The Opitutaceae are a Gram-negative and chemoheterotrophic order of the domain Bacteria. Opitutaceae bacteria were isolated from soil and coastal marine springs.
