Pseudomonas stutzeri

Description and Significance

Description of the appearance, habitat, etc. of the organism, and why it is important. -denitrifying, nonflueorescing -found abundantly in environment, also opportunistic pathogen isolated in clinical setting (one of these clinical strains sequenced, the other two from environment I believe) -Oxygen used as terminal e acceptor, but ALL strains are also able to use nitrate as e acceptor as well (generally under anaerobic conditions) -colonies appear reddish brown, wrinkled, cratered, hard and can easily be removed entirely from the media they were grown on -monotrichous cells typically motile -opportunistic pathogen with low virulence -large range of growth conditions given that it can use multiple e receptors for anabolic metabolism, also can use a variety of C sources for energy -found in soils, the human body, marine habitats, and wastewater

Genome Structure

Description of the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence? Three clinical strains of Psuedomonas stutzeri have been completely sequenced, providing a great deal of information about the content of the genome. The genome is encoded on a singular chromosome which is circular. No plasmids were detected in any of the three sequences. The length of the chromosome of one particular strain was 4,547,930 bp, with the two other strains both being slightly longer. Genes for denitrification were found in two strains, but were absent in a third. All three strains contained genes encoding for benzoate and catechol degradation, as well as chemotaxis. -may want to go into greater detail about the differences found in the genomes between the three sequenced strains?

Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.

1-3um by 0.5um. Rod-shaped, usually with one flagellum

They are denitrifiers. (let's go into what that means)

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
