The Comamonadaceae are a family of the Betaproteobacteria. [3] 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. [4]
The Hyphomicrobiales are an order of Gram-negative Alphaproteobacteria.
The Oceanospirillales are an order of Pseudomonadota with ten families.
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 Alteromonadaceae are a family of Pseudomonadota. They are now one of several families in the order Alteromonadales, including Alteromonas and its closest relatives. Species of this family are mostly rod-like shaped and motile by using one polar flagellum.
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.
Bacteroidales is an order of bacteria. Notably it includes the genera Prevotella and Bacteroides, which are commonly found in the human gut microbiota.
Variovorax is a Gram-negative and motile genus of bacteria from the family Comamonadaceae. It belong to the class called Betaproteobacteria. It is an aerobic bacteria and most of its species is found in soil and freshwater. The demographic distribution of this species is primarily in Europe, Asia and the Americas, as well as the polar regions. Its designated species is Variovorax paradoxus which arose from the species Alcaligenes paradoxus being grouped under the Variovorax genus. Variovorax paradoxus constitutes to the methylotrophic microbiota of the human mouth.
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
The Lachnospiraceae are a family of obligately anaerobic, variably spore-forming bacteria in the order Eubacteriales that ferment diverse plant polysaccharides to short-chain fatty acids and alcohols (ethanol). These bacteria are among the most abundant taxa in the rumen and the human gut microbiota. Members of this family may protect against colon cancer in humans by producing butyric acid. Lachnospiraceae have been found to contribute to diabetes in genetically susceptible (ob/ob) germ-free mice.
Acidicapsa is a bacterial genus from the family of Acidobacteriaceae.
Ilumatobacter is a genus from the order Acidimicrobiales.
Desulfosarcina is a Gram-negative and strictly anaerobic bacteria genus from the family of Desulfosarcinaceae.
Luteococcus is a bacterial genus from the family Propionibacteriaceae.
Tessaracoccus is a Gram-positive, non-spore-forming, facultatively anaerobic and non-motile bacterial genus from the family Propionibacteriaceae.
Marmoricola is a Gram-positive and chemoorganotrophic bacterial genus from the family of Nocardioidaceae.
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.
Blastococcus is a Gram-positive, coccoid and aerobic genus of bacteria from the family of Geodermatophilaceae.
Hippea is an obligate anaerobic and moderately thermophilic bacteria genus from the family of Desulfobacteraceae. Hippea is named after the German microbiologist Hans Hippe.
Heliorestis is an alkaliphilic genus of bacteria from the family of Heliobacteriaceae.
