Thermithiobacillus is a genus of nonsporeforming, rod-shaped, Gram-negative bacteria. The name derives from the Latin thermae, for warm baths, and the Classical Greek θείος, theios for sulfur. The type species of this genus was previously assigned to the genus Thiobacillus, but it was reclassified on the basis of 16S rRNA analysis in 2000, creating this genus.
The Gemmatimonadota are a phylum of bacteria established in 2003. The phylum contains two classes Gemmatimonadetes and Longimicrobia.
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.
Polynucleobacter is a genus of bacteria, originally established by Heckmann and Schmidt (1987) to exclusively harbor obligate endosymbionts of ciliates belonging to the genus Euplotes.
Limnohabitans is a genus of bacteria established by Hahn et al. (2010). The genus contains four species which all represent planktonic bacteria dwelling in the water column of freshwater lakes, reservoirs, and streams.
Limnohabitans curvus is an aerobic, nonmotile bacterium from the genus Limnohabitans and family Comamonadaceae, which was isolated from the pelagic zone from a freshwater lake in Mondsee in Austria.
Roseateles aquatilis is a Gram-negative, oxidase-positive, catalase-negative, aerobic, rod-shaped bacterium with a single polar flagellum from the genus Roseateles, which was isolated from industrial water and fresh water. Colonies of R. aquatilis are clear.
Polynucleobacter necessarius is a bacterium of the genus Polynucleobacter.
Polynucleobacter difficilis is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, freshwater bacterium of the genus Polynucleobacter, isolated from the Lake Sevan from a depth of 60 m in Armenia.
Dyadobacter is a genus of gram negative rod-shaped bacteria belonging to the family Spirosomaceae in the phylum Bacteroidota. Typical traits of the genus include yellow colony colour, positive flexirubin test and non-motile behaviours. They possess an anaerobic metabolism, can utilise a broad range of carbon sources, and test positive for peroxide catalase activity. The type species is Dyadobacter fermentans, which was isolated from surface sterilised maize leaves,.
Polynucleobacter asymbioticus is an aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, free-living bacterium of the genus Polynucleobacter. The type strain was isolated from a small pond located in the Austrian Alps in the area of Salzburg and described as a new subspecies of Polynucleobacter necessarius in 2009. The classification of the type strain was hampered by the fact that its closest described relative represented obligate endosymbionts, i.e. P. necessarius, not available as a pure culture suitable for standard tests for delineation of prokaryotic species. Therefore, the strain was preliminarily placed in the subspecies P. necessarius subsp. asymbioticus. Later sequencing of the genome of the type strain revealed that the strain represented a novel species within the genus Polynucleobacter. Therefore, its taxonomic rank was lifted from the subspecies to the species level. Strains of P. asymbioticus dwell as planktonic organisms in acidic, humic-rich freshwater systems. Comparative genome analyses revealed that P. asymbioticus represents an atypical member of the family Burkholderiaceae regarding its small genome size and its passive lifestyle. A recent study used a collection of 37 P. asymbioticus strains isolated from various ponds located in a larger region of the Austrian Alps to gain insights in the evolution of Polynucleobacter bacteria.
Polynucleobacter wuianus is an aerobic, chemo-organotrophic, catalase- and oxidase-positive, free-living bacterium of the genus Polynucleobacter, isolated from a small pond located in the Austrian Alps in the area of Salzburg. Bacteria affiliated with this species represent planktonic bacteria (bacterioplankton) dwelling in acidic freshwater systems. The species was named after the Chinese limnologist and microbiologist Qinglong L. Wu who isolated the type strain.
The Silvanigrellales are an order of the phylum Bdellovibrionota. They include currently only the single family Silvanigrellaceae.
Silvanigrella is a genus of the phylum Bdellovibrionota. The genus currently contains two described species: Silvanigrella aquatica and Silvanigrella paludirubra.
Rhodoluna is a Gram-positive, non-spore-forming and non-motile genus of bacteria from the family of Microbacteriaceae. The type strain of the only species Rhodoluna lacicola encodes an actinorhodopsin, which is a light-diven proton pump enabling light energy conversion, potentially resulting in a mixotrophic physiology. The type strain of R. lacicola was isolated from Lake Tai in China. The type strain MWH-Ta8 is remarkable for its very small cell size ultramicrobacterium and its small genome size of only 1.4 Mbp. The type strain has a planktonic lifestyle, that is freely floating the water column of aquatic systems. Currently, the genus Rhodoluna contains two described species.
Polynucleobacter sphagniphilus is an aerobic, chemo-organotrophic, non-motile, free-living bacterium of the genus Polynucleobacter.
Terrimesophilobacter mesophilus is a Gram-positive, aerobic, mesophilic and motile bacterium from the genus of Terrimesophilobacter which has been isolated from soil from a field from Bigeum Island in Korea.
Bacteriovoracales is an order of bacteria.
Aquiluna is a genus of bacteria from the order Actinomycetales. As of 2022, Aquiluna is a monotypic genus, with the only validly published species being Aquiluna borgonia. The genus was first proposed in 2009, but its type species Candiatus Aquiluna rubra was not validly published.
