Pseudomonas fluorescens has multiple flagella, an extremely versatile metabolism, and can be found in the soil and in water.It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.
Pyrrolnitrin (PRN [1]) is a naturally occurring phenylpyrrole fungicide. [2] Pseudomonas and Burkholderia species produce pyrrolnitrin from tryptophan as secondary metabolite. [3] [4] It is believed that the antifungal properties come from inhibition of electron transport system.
2,4-Diacetylphloroglucinol or Phl [1] [2] is a natural phenol found in several bacteria: . Specific strains of the Gram-negative bacterium Pseudomonas fluorescens. [3] This compound is found to be responsible for the antiphytopathogenic [4] and biocontrol [5] properties in these strains.
In 2000, the complete genome of a Pseudomonas species was sequenced; more recently, the genomes of other species have been sequenced, including P. aeruginosa PAO1 (2000), P. putida KT2440 (2002), P. fluorescens Pf-5 (2005), P. fluorescens PfO-1, and P. entomophila L48.
The type that most commonly infects humans is Pseudomonas aeruginosa, which can lead to infections in the blood, lungs or other parts of the body, the CDC says. The agency points out that ...
"Biosynthesis of the antibiotic obafluorin from D-[U-13 C]glucose and p-aminophenylalanine in Pseudomonas fluorescens". Journal of the Chemical Society, Perkin Transactions 1 (1): 103– 107. doi : 10.1039/P19920000103 .
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]
The peptide chain produced by a given strain of Pseudomonas is currently thought to be invariant. Little is known about the particular function or importance of the ketoacid side chain, but it is well known [ 12 ] that pyoverdine molecules with different ketoacids ( congeners ) co-exist.
