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.
The phylum comprises six classes Acidithiobacilia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia, and Zetaproteobacteria. [11] The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence.
Taksonomi. Rujukan. Proteobacteria adalah salah satu filum bakteri. Anggotanya mencakup berbagai bakteri patogen ternama, seperti Escherichia, Salmonella, Vibrio, dan Helicobacter, [1] serta bakteri yang sanggup ber simbiosis untuk menyemat nitrogen dari udara dan meng oksidasinya menjadi nitrat.
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.
All known PS bacteria belong to the “Gammaproteobacteria” and use H 2 S or S° as sole electron donor. The PNS bacteria occur among the “Alphaproteobacteria” and “Betaproteobacteria.” A great number of phototrophic Proteobacteria are versatile and can easily switch from a phototrophic to a heterotrophic lifestyle in the absence of ...
Mar 5, 2010 · The phylogeny of the large bacterial class Gammaproteobacteria has been difficult to resolve. Here we apply a telescoping multiprotein approach to the problem for 104 diverse gammaproteobacterial genomes, based on a set of 356 protein families for the ...
