Pseudomonadota (synonym "Proteobacteria") is a major phylum of Gram-negative bacteria. [10] Currently, they are considered the predominant phylum within the realm of bacteria. [ 11 ] They are naturally found as pathogenic and free-living (non- parasitic ) genera. [ 11 ]
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria.The 348 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches and hosts.
Mariprofundus ferrooxydans PV-1 twisted stalks TEM image. One example of Fe oxide morphotypes produced by the Zetaproteobacteria. Image by Clara Chan. The Zetaproteobacteria were first discovered in 1991 by Craig Moyer, Fred Dobbs and David Karl as a single rare clone in a mesophilic, or moderate temperature, hydrothermal vent field known as Pele's Vents at Kamaʻehuakanaloa Seamount (formerly ...
Gammaproteobacteria is a class of bacteria in the phylum Pseudomonadota (synonym Proteobacteria). It contains about 250 genera, which makes it the most genus-rich taxon of the Prokaryotes. [1] Several medically, ecologically, and scientifically important groups of bacteria belong to this class. All members of this class are Gram-negative.
It is found in soil, water, skin flora, and most human-made environments throughout the world. As a facultative anaerobe , P. aeruginosa thrives in diverse habitats. It uses a wide range of organic material for food; in animals, its versatility enables the organism to infect damaged tissues or those with reduced immunity.
The Aeromonadaceae are Gram-negative bacteria. [2] The species are facultative anaerobic organisms. [3] The cells are rod-shaped. They are mostly found in estuarine waters and fresh water, also in soil and sewage.
Alphaproteobacteria or α-proteobacteria, also called α-Purple bacteria in earlier literature, is a class of bacteria in the phylum Pseudomonadota (formerly "Proteobacteria"). [4] The Magnetococcales and Mariprofundales are considered basal or sister to the Alphaproteobacteria .
To illustrate the incredible diversity of hydrothermal vents, the list below is a cumulative representation of bacterial phyla and genera, in alphabetical order. As shown, proteobacteria appears to be the most dominant phyla present in deep-sea vents. Actinomycetota [16] Aquificota. Hydrogenobacter and Aquifex [15] [16] Chloroflexota [16 ...
