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.
5 days ago · Learning Objectives. Describe the unique features of each class within the phylum Proteobacteria: Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Deltaproteobacteria, and Epsilonproteobacteria. Give an example of a bacterium in each class of Proteobacteria.
Dec 24, 2022 · Gammaproteobacteria is a class of several medically, ecologically and scientifically important groups of bacteria, such as the Enterobacteriaceae ( Escherichia coli ), Vibrionaceae and Pseudomonadaceae. Like all Proteobacteria, the Gammaproteobacteria are Gram-negative.
Gammaproteobacteria consists of human pathogens (e.g., Pseudomonas aeruginosa Salmonella, Vibrio, and Yersinia,); some genera are methane oxidizers and some genera are in symbiosis with hydrothermal vent dwelling animals. Pseudomonas aeruginosa is a stringently aerobic, nonfermenting motile bacterium.
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria. The 313 members of the genus [2] [3] demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. [4] .
Dec 24, 2022 · Key Points. Proteobacteria include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera. All proteobacteria are Gram-negative, with an outer membrane mainly composed of lipopolysaccharides.
