Polaromonas is a genus of Gram-negative bacteria from the family Comamonadaceae. [1] [2] Polaromonas species are psychrophiles. [1] [3]
Rhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Rhizobium species form an endosymbiotic nitrogen-fixing association with roots of legumes and Parasponia.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcus–Thermus group. It includes the following species:
The Aurantimonadaceae are a small family of marine bacteria. Six species are known. Aurantimonas coralicida causes a white plague in corals. Fulvimarina pelagi was isolated from seawater, and takes the form of nonmotile rods.
Fibrobacteres is a small bacterial phylum which includes many of the major rumen bacteria, allowing for the degradation of plant-based cellulose in ruminant animals. Members of this phylum were categorized in other phyla. The genus Fibrobacter was removed from the genus Bacteroides in 1988.
Epsilonproteobacteria are a class of Proteobacteria. All species of this class are, like all Proteobacteria, Gram-negative.
Enterobacter cloacae is a clinically significant Gram-negative, facultatively-anaerobic, rod-shaped bacterium.
Alteromonas is a genus of Proteobacteria found in sea water, either in the open ocean or in the coast. It is Gram-negative. Its cells are curved rods with a single polar flagellum.
The Chloroflexi or Chlorobacteria are a phylum of bacteria containing isolates with a diversity of phenotypes, including members that are aerobic thermophiles, which use oxygen and grow well in high temperatures; anoxygenic phototrophs, which use light for photosynthesis ; and anaerobic halorespirers, which uses halogenated organics as electron acceptors.
Tannerella forsythia is an anaerobic, Gram-negative bacterial species of the Cytophaga-Bacteroidetes family. It has been implicated in periodontal diseases and is a member of the red complex of periodontal pathogens. T. forsythia was previously named Bacteroides forsythus and Tannerella forsythensis.
Nitrospirae is a phylum of bacteria. It contains only one class, Nitrospira, which itself contains one order (Nitrospirales) and one family (Nitrospiraceae). It includes multiple genera, such as Nitrospira, the largest. The first member of this phylum, Nitrospira marina, was discovered in 1985. The second member, Nitrospira moscoviensis, was discovered in 1995.
Thermoanaerobacter is a genus in the phylum Firmicutes (Bacteria). Members of this genus are thermophilic and anaerobic, several of them were previously described as Clostridium species and members of the now obsolete genera Acetogenium and Thermobacteroides
Demequina is a genus in the phylum Actinobacteria (Bacteria).
Agromyces is a genus in the phylum Actinobacteria (Bacteria).
Algoriphagus is a genus in the phylum Bacteroidetes (Bacteria).
Alistipes is a genus in the phylum Bacteroidetes (Bacteria).
Armatimonadetes is a phylum of gram-negative bacteria.
Polaromonas glacialis is a Gram-negative, psychrophilic bacterium from the genus Polaromonas, which was isolated with Polaromonas cryoconiti from an alpine glacier.
Polaromonas hydrogenivorans is a Gram-negative, nonmotile, non-spore-forming, psychrotolerant bacterium from the genus Polaromonas, which was isolated from Alaskan forest soil. P. hydrogenivorans has the ability to oxidize hydrogen and its colonies are white.
Polaromonas naphthalenivorans is a Gram-negative, oxidase- and catalase-positive, non-spore-forming, nonmotile bacterium from the genus Polaromonas, which was isolated from coal-tar contaminated freshwater sediment. P. naphthalenivorans has the ability to degrade naphthalene. Its colonies have a smooth and glistening surface.
The Nautiliaceae are a family of bacteria placed in an order to itself, Nautiliales, or in the order Campylobacterales. The members of the family are all thermophilic. They are:
