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 also include a second membrane and are therefore 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.
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Bacillota. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Rhodoplanes is a phototrophic genus of bacteria. Rhodoplanes produces hopanoids like diplopterol, tetrahymanol, 2-methyldiplopterol, 2-methyltetrahymanol, bacteriohopanetetrol, bacteriohopaneaminotriol and carotenoids like spirilloxanthin, rhodopin, anhydrorhodovibrin, 1,1′-dihydroxylycopene and 3,4,3′,4′-tetrahydrospirilloxanthin
Sphingomonas aurantiaca is a Gram-negative and psychrotolerant bacteria from the genus of Sphingomonas which has been isolated from indoor dusts from animal sheds in Finland.
Sphingomonas faeni is a Gram-negative bacteria from the genus of Sphingomonas which has been isolated from indoor dusts from animal sheds in Finland.
Ammoniphilus is a Gram-variable, strictly aerobic, rod-shaped, haloalkalitolerant spore-forming, obligately oxalotrophic and motile bacterial genus from the family of Paenibacillaceae with peritrichous flagella. In the cell wall of Ammoniphilus is meso-diaminopimelic acid.
Arcicella is a genus of aerobic bacteria from the family of Spirosomaceae.
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.
Roseomonas rosea is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pink-colored bacteria. It was first isolated from a children's day care center in 1995. Further work on the isolate led to the proposal of a new genus and species, Muricoccus roseus in 2003. Further work on M. roseus found that the species belonged in the genus Roseomonas, and also led to Teichococcus ludipueritiae being reclassified as Roseomonas ludipueritiae in 2009. The new name for the species is Roseomonas rosea. The species name is derived from Latin rosea (pink), referring to the pink color the bacterial colonies will form, which is also a present in most Roseomonas species.
Roseomonas gilardii is a species of Gram negative, strictly aerobic, coccobacilli-shaped, pink-pigmented bacterium. It is the type species of the genus Roseomonas. The new species was among the first Roseomonas species proposed in 1993, and is named for "Gerald L. Gilardi for his many contributions to bacteriology and, specifically, for his contributions in the area of glucose-nonfermenting gram-negative rods." R. gilardii is pathogenic for humans, causing bacteremia and other infections.
Frigoribacterium is a Gram-positive, non-spore-forming and motile genus of bacteria from the family of Microbacteriaceae.
