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.
Adhaeribacter is a genus in the phylum Bacteroidota (Bacteria).
Naxibacter suwonensis is a Gram-negative aerobic motile with a single flagellum, and rod-shaped bacterium which was isolated with Massilia jejuensis from air samples on the Jeju Island and Suwon region of Korea.
Massilia aerilata is an aerobic, Gram-negative, rod-shaped, motile bacterium from the genus Massilia and the family Oxalobacteraceae which was isolated from air samples in the Suwon region of the Republic of Korea. 16S rRNA gene sequence analysis have shown that it belongs to the genus of Massilia. Colonies of M. aerilata are light yellow.
Massilia albidiflava is a Gram-negative, rod-shaped, oxidase and catalase positive, non-spore-forming motile bacterium from the genus Massilia and the family Oxalobacteraceae which was isolated with Massilia dura, Massilia plicata, and Massilia lutea from soil samples in southeast China.
Massilia aurea is a Gram-negative, rod-shaped non-spore-forming motile and strictly aerobic bacterium from the genus Massilia and family Oxalobacteraceae. It was isolated from the drinking water distribution system in Seville, Spain. M. aurea produces yellow-pigmented colonies.
Massilia consociata is a Gram-negative, non-spore-forming, rod-shaped bacterium from the genus Massilia and family Oxalobacteraceae, which was isolated from a human clinical specimen. Its 16S rRNA gene sequence has shown that M. consociata belongs to the class Betaproteobacteria and is closely related to Naxibacter varians.
Massilia dura is a Gram-negative, rod-shaped, non-spore-forming bacterium from the genus Massilia and family Oxalobacteraceae, which was isolated with Massilia albidiflava, Massilia plicata, and Massilia lutea from soil samples collected from southeast China. Colonies of M. dura are hard and compact and their color is pale white to yellow.
Massilia jejuensis is a Gram-negative, aerobic, rod-shaped, motile bacterium with a single flagellum from the genus Massilia and family Oxalobacteraceae, which was isolated with Naxibacter suwonensis from air samples in the Jeju Island and Suwon region of Korea. Colonies of M. jejuensis are light orange.
Massilia lutea is a Gram-negative, non-spore-forming, short rod-shaped, motile bacterium with a peritrichous flagellum from the genus Massilia and family Oxalobacteraceae.
Massilia niabensis is a Gram-negative, aerobic, motile, rod-shaped bacterium from the genus Massilia and family Oxalobacteraceae, which was isolated with Massilia niastensis from air samples from Suwon in Korea. Colonies of M. niabensis are yellowish white.

Roseomonas is a genus of Gram negative bacteria. The cells are coccoid rods when viewed microscopically. Certain species are known to be opportunistic infections for humans.
Sediminibacillus is a genus of bacteria from the family of Bacillaceae. Sediminibacillus species are halophilic bacteria and found in salty human stools and marine sponges. Sediminibacillus species are identified from Plakortis dariae sponge of the Saint Martin's island of the Bay of Bengal, Bangladesh.
Janibacter is a genus of Gram positive, nonmotile, non-sporeforming bacteria. The genus name is derived from the two-faced Roman god Janus, referring to the fact that the cells of the original strain could be rod-shaped or coccoid.
Janibacter hoylei is a species of Gram positive, aerobic, bacterium. The species was initially isolated from cryovials that sampled high altitude air between 20 and 41 km above sea level. The species was first described in 2009, and the species is named after English astronomer Fred Hoyle. Two other new species were discovered during the same survey: Bacillus isronensis and Bacillus aryabhattai.
Terrabacter aeriphilus is a species of Gram-positive, nonmotile, non-endosporeforming bacteria. Cells are either rods or coccoid. It was initially isolated from an air sample in Taean County, South Korea. The species was first described in 2010, and its name is derived from Latin aer (air), and Greek philos (loving).
Terrabacter aerolatus is a species of Gram-positive, nonmotile, non-endosporeforming bacteria. Cells are either rods or coccoid. It was initially isolated from an air sample in Jeju Province, South Korea. The species was first described in 2007, and its name is derived from Latin aer (air) and latus (carried).
