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.
The phylum comprises six classes Acidithiobacilia, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Hydrogenophilia, and Zetaproteobacteria. The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence.
Dec 24, 2022 · Gammaproteobacteria include an exceeding number of important pathogens, e.g. Salmonella, Yersinia, Vibrio, Pseudomonas aeruginosa. Like all Proteobacteria, the Gammaproteobacteria are Gram-negative. Some Gammaproteobacteria are methane oxidizers, and many of them are in symbiosis with geothermic ocean vent dwelling animals.
Gammaproteobacteria. are ubiquitous Gammaproteobacteria that utilize a wide array of organic compounds, produce diverse secondary metabolites and antibiotics, colonize eukaryotic hosts, and inhibit plant and animal pathogens (Moore et al., 2006; From: Advances in Applied Microbiology, 2021
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria. The 313 members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches.
Sep 30, 2021 · The relative abundance of Gammaproteobacteria was significantly and directly correlated with the levels of oxidative stress and locomotive ability of the host. These results strongly supported Gammaproteobacteria as a potential indicator taxon in response to soil pollution, although limited to the environmental concentrations in this study.
Mar 5, 2010 · An initial set of protein families that approximated one occurrence per genome among 97 Gammaproteobacteria were selected from the GeneTrees database , and the alignments were used for HMMsearch using HMMer to find instances in the full set of 215 genomes. The 20 gene families with the lowest standard deviation of members per genome, the ...
