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. The Pseudomonadota are widely diverse, with differences in morphology, metabolic processes, relevance to humans, and ecological influence.
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. 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
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 whole class and even larger sets for each of four cohesive subregions of the tree.
Jules J. Berman, in Taxonomic Guide to Infectious Diseases, 2012. Class Gamma Proteobacteria holds in excess of 20 genera containing about four dozen species that infect humans. It would be unproductive to describe each species in this large and heterogeneous group of organisms. The infectious Gamma Proteobacteria are best understood by ...
1 Introduction. The gamma-proteobacterium Methylococcus capsulatus (Bath) is one of the most extensively studied methanotrophs. It is ubiquitous in nature and has frequently been used in commercial pilot studies involving methanotrophs ( Larsen and Joergensen, 1996; Murrell, 2010 ). Electron micrographs show that its cell envelope contains a ...
