Chitinophagaceae is an aerobic or facultatively anaerobic and rod-shaped family of bacteria in the phylum Bacteroidota. [4] [5] [6] [7] [8]
The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature [4] and the phylogeny is based on whole-genome sequences. [9] [lower-alpha 1]
The Thermoproteota are prokaryotes that have been classified as a phylum of the Archaea domain. Initially, the Thermoproteota were thought to be sulfur-dependent extremophiles but recent studies have identified characteristic Thermoproteota environmental rRNA indicating the organisms may be the most abundant archaea in the marine environment. Originally, they were separated from the other archaea based on rRNA sequences; other physiological features, such as lack of histones, have supported this division, although some crenarchaea were found to have histones. Until recently all cultured Thermoproteota had been thermophilic or hyperthermophilic organisms, some of which have the ability to grow at up to 113 °C. These organisms stain Gram negative and are morphologically diverse, having rod, cocci, filamentous and oddly-shaped cells.
The Hyphomicrobiaceae are a family of bacteria. Among others, they include Rhodomicrobium, a genus of purple bacteria.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
The Pseudonocardiaceae are a family of bacteria in the order Actinomycetales and the only member of the suborder Pseudonocardineae.
Deinococcus is in the monotypic family Deinococcaceae, and one genus of three in the order Deinococcales of the bacterial phylum Deinococcota highly resistant to environmental hazards. These bacteria have thick cell walls that give them Gram-positive stains, but they include a second membrane and so are closer in structure to Gram-negative bacteria. Deinococcus survive when their DNA is exposed to high doses of gamma and UV radiation. Whereas other bacteria change their structure in the presence of radiation, such as by forming endospores, Deinococcus tolerate it without changing their cellular form and do not retreat into a hardened structure. They are also characterized by the presence of the carotenoid pigment deinoxanthin that give them their pink color. They are usually isolated according to these two criteria. In August 2020, scientists reported that bacteria from Earth, particularly Deinococcus bacteria, were found to survive for three years in outer space, based on studies conducted on the International Space Station. These findings support the notion of panspermia, the hypothesis that life exists throughout the Universe, distributed in various ways, including space dust, meteoroids, asteroids, comets, planetoids or contaminated spacecraft.
Pararhizobium is a genus of Gram-negative soil bacteria that fix nitrogen. Some species of Pararhizobium form an endosymbiotic nitrogen-fixing association with roots of legumes.
Thermonema is a Gram-negative, chemoheterotrophic and aerobic genus from the phylum Bacteroidota.
Niastella is a bacterial genus from the family of Chitinophagaceae.
Coprothermobacterota is a phylum of nonmotile, rod-shaped bacteria.
Hydrotalea flava is a bacterium from the genus of Hydrotalea which has been isolated from industry distilled water from Sweden.
Niveitalea is a Gram-negative, and strictly aerobic genus of bacteria from the family of Chitinophagaceae with one known species. Niveitalea solisilvae has been isolated from forest soil from the Jeju island in Korea.
Chitinophaga is a genus of bacteria from the family of Chitinophagaceae.
Nitrospinota is a bacterial phylum. Despite only few described species, members of this phylum are major nitrite-oxidizing bacteria in surface waters in oceans. By oxidation of nitrite to nitrate they are important in the process of nitrification in marine environments.
The Rhodothermales are an order of bacteria.
Balneolales is an order of bacteria.
Saprospirales is an order of bacteria in the phylum Bacteroidota.
Hymenobacteraceae is a family of bacteria in the phylum Bacteroidota.
Persicobacteraceae is a family of bacteria in the phylum Bacteroidota.
Crocinitomicaceae is a family of bacteria in the order Flavobacteriales.
Thermoguttaceae is a family of bacteria.
