What are the Pseudomonas species?

What are the Pseudomonas species?

These include P aeruginosa, P fluorescens, P putida, P cepacia, P stutzeri, P maltophilia, and P putrefaciens. Only two species, P mallei and P pseudomallei, produce specific human diseases: glanders and melioidosis.

What are the characteristics of Pseudomonas?


  • Rod-shaped.
  • Gram-negative.
  • Flagellum one or more, providing motility.
  • Aerobic.
  • Non-spore forming.
  • Catalase-positive.
  • Oxidase-positive.

What are the major distinctive properties of the bacteria in the genus Pseudomonas?

Pseudomonas spp. belong to the family Pseudomonadaceae and are psychrophilic catalase-positive obligate aerobic (i.e. they require presence of O2 to survive) Gram-negative bacteria. They are usually single curved (banana like) or in the shape of straight rods. They are made mobile by polar flagella.

What are the uses of Pseudomonas?

Pseudomonas aeruginosa has beneficial uses in various industrial and commercial sectors around the globe. These include waste degradation, oil refineries, textile products, agriculture, pulp and paper, mining, and explosive industries.

What are the names of the other genera of Pseudomonas?

Other strains previously classified in the genus Pseudomonas are now classified in the genera Burkholderia and Ralstonia.

What kind of exopolysaccharide does Pseudomonas secrete?

A significant number of cells can produce exopolysaccharides associated with biofilm formation. Secretion of exopolysaccharides such as alginate makes it difficult for pseudomonads to be phagocytosed by mammalian white blood cells.

How are Pseudomonas able to survive in harsh conditions?

Aminoglycosides such as tobramycin, gentamicin, and amikacin are other choices for therapy. This ability to thrive in harsh conditions is a result of their hardy cell walls that contain porins. Their resistance to most antibiotics is attributed to efflux pumps, which pump out some antibiotics before they are able to act.

What kind of compounds can Pseudomonas degrade with cyanide?

P. pseudoalcaligenes, which is able to use cyanide as a nitrogen source. P. resinovorans, which can degrade carbazole. P. veronii, which has been shown to degrade a variety of simple aromatic organic compounds.
