Alteromonas is a genus of Pseudomonadota [1] 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 etymology of the genus is Latin alter -tera -terum, another, different; monas (μονάς), a noun with a special meaning in microbiology used to mean unicellular organism; to give Alteromonas, another monad [2]
Members of the genus Alteromonas can be referred to as alteromonads (viz. Trivialisation of names).
The genus was described by Baumann et al. in 1972, [3] but was emended by Novick and Tyler 1985 to accommodate Alteromonas luteoviolacea (now Pseudoalteromonas luteoviolacea ), [4] Gauthier et al. 1995, who split the genus in two ( Pseudoalteromonas ) [5] and Van Trappen et al. in 2004 to accommodate Alteromonas stellipolaris. [6]
"Alteromonas-like sub-group" has been identified by microbial culture, metagenomics, and FISH-probe microscopy in the typhlosole sub-organ of the shipworm cecum as a symbiont digesting lignin. [7]
The genus contains eight species (but 21 basonyms), namely [2]
Many alteromonads were reclassified as members of Pseudoalteromonas in 1995 [5]
Other former alteromonads:
Pseudoalteromonas is a genus of marine bacteria. In 1995, Gauthier et al proposed Pseudoalteromonas as a new genus to be split from Alteromonas. The Pseudoalteromonas species that were described before 1995 were originally part of the genus Alteromonas, and were reassigned to Pseudoalteromonas based on their rRNA-DNA analysis.
Thermus is a genus of thermophilic bacteria. It is one of several bacteria belonging to the Deinococcota phylum. According to comparative analysis of 16S rRNA, this is one the most ancient group of bacteria Thermus species can be distinguished from other genera in the family Thermaceae as well as all other bacteria by the presence of eight conserved signature indels found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins that are exclusively shared by members of this genus.
Halomonadaceae is a family of halophilic Pseudomonadota.
Pseudoalteromonas piscicida is a marine bacterium. It is known to produce a quorum sensing molecule called 2-heptyl-4-quinolone (HHQ), which functions as a bacterial infochemical. Research into the effects of this infochemical on phytoplankton is currently being conducted by Dr. Kristen Whalen of Haverford College.
Algicola is a genus in the phylum Pseudomonadota (Bacteria).
Alishewanella is a genus in the phylum Pseudomonadota (bacteria).
Pseudoalteromonas aurantia is an antibacterial-producing marine bacterium commonly found in Mediterranean waters. In 1979, Gauthier and Breittmayer first named it Alteromonas aurantia to include it in the genus Alteromonas that was described seven years earlier, in 1972 by Baumann et al. In 1995, Gauthier et al renamed Alteromonas aurantia to Pseudoalteromonas aurantia to include it in their proposed new genus, Pseudoalteromonas, which they recommended splitting from Alteromonas.
Pseudoalteromonas citrea is a yellow-pigmented marine bacterium that is antibiotic-producing and was isolated from Mediterranean waters off Nice. Originally named Alteromonas citrea, nearly two decades later it was reclassified as part of the Genus Pseudoalteromonas.
Pseudoalteromonas denitrificans is a marine bacterium.
Pseudoalteromonas distincta is a marine bacterium.
Pseudoalteromonas espejiana is a marine bacterium.
Pseudoalteromonas luteoviolacea is a marine bacterium which was isolated from seawater near Nice.
Pseudoalteromonas rubra is a marine bacterium.
Pseudoalteromonas tetraodonis is a marine bacterium isolated from the surface slime of the puffer fish. It secretes the neurotoxin, tetrodotoxin. It was originally described in 1990 as Alteromonas tetraodonis but was reclassified in 2001 to the genus Pseudoalteromonas.
Pseudoalteromonas undina is a marine bacterium isolated from seawater off the coast of Northern California. It was originally classified as Alteromonas undina but was reclassified in 1995 to the genus Pseudoalteromonas.
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.
Margalitia is a genus of gram-positive or gram-variable rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Margalitia shackletonii.
Robertmurraya is a genus of mostly Gram-Positive rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Robertmurraya siralis.
Rossellomorea is a genus of Gram-Positive or Gram-variable staining rod-shaped bacteria in the family Bacillaceae from the order Bacillales. The type species of this genus is Rossellomorea aquimaris.
