Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. Th ...

capabilities and other species that cause spoilage of milk and dairy products. ''Pseudomonas aeruginosa'' can cause chronic opportunistic infections that have become increasingly apparent in immunocompromised patients and the ageing population of industrialised societies. The genome sequences of several pseudomonads have become available in recent years and researchers are beginning to use the data to make new discoveries about this bacterium.

'' is a group of Gram-negative, nonmotile and nonfermentative bacteria belonging to the family Moraxellaceae. They are important soil organisms where they contribute to the mineralisation of, for example, aromatic compounds. ''Acinetobacter'' species are able to survive on various surfaces (both moist and dry) in the hospital environment, thereby being an important source of infection in debilitated patients. These bacteria are innately resistant to many classes of

Gamma-150 RNA motif
The gamma-150 RNA motif is a conserved RNA structure that is found in bacteria within the order Pseudomonadales. Because gamma-150 RNAs are not consistently in 5' UTRs, the gamma-150 motif is presumed to correspond to a non-coding RNA.
