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 ]
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 ...
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.
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.
These bacteria are found in all environments that support life on Earth. Within this category, notable species include the model organism Escherichia coli , along with various pathogenic bacteria , such as Pseudomonas aeruginosa , Chlamydia trachomatis , and Yersinia pestis .
Another example, Thermochromatium tepidum, has been found in several hot springs in western North America at temperatures above 58 °C (136 °F) and may represent the most thermophilic extant Pseudomonadota. [30] Of the purple sulfur bacteria, many members of the Chromatiaceae family are often found in fresh water and marine
Alphaproteobacteria is a type of proteobacteria, and it can be divided into several different orders, including Rhodobacterales, Rhodospirillales, and Caulobacterales. Although there are numerous orders of Alphaproteobacteria, there are over 100 families of bacteria within the class. Among these, the most abundant is the Pelagibacteraceae ...
The Pelagibacterales are an order in the Alphaproteobacteria composed of free-living marine bacteria that make up roughly one in three cells at the ocean's surface. [2] [3] [4] Overall, members of the Pelagibacterales are estimated to make up between a quarter and a half of all prokaryotic cells in the ocean.
