What is Pseudomonas putida used for?

What is Pseudomonas putida used for?

Pseudomonas putida is capable of converting styrene oil into the biodegradable plastic PHA. This may be of use in the effective recycling of polystyrene foam, otherwise thought to be not biodegradable.

Is Pseudomonas putida a plant pathogen?

Pseudomonas putida is a saprophytic soil bacterium that has the capacity to colonize the root of crop plants (Espinosa-Urgel et al., 2000; Molina et al., 2000). It is a well-established biocontrol agent that provides growth advantages to the plant (Weller, 2007). In this study we identified and characterized the P.

Is Pseudomonas putida genetically modified?

Pseudomonas putida WCS358r, genetically modified to have improved activity against soil-borne pathogens, was released into the rhizosphere of wheat.

What diseases does Pseudomonas putida cause?

Pseudomonas putida is an uncommon cause of skin and soft tissue infections. It is often associated with trauma or immunocompromised state. We present the first lethal case of bacteremia due to skin and soft tissue infections, which had malnutrition, immobility, and peripheral vascular disease as risk factors.

Is Pseudomonas putida used to clean oil spills?

These bacteria are known as hydrocarbon degrading bacteria. Pseudomonas can digest the hydrocarbons in oil. They are gram negative bacteria that are found in soil, water and plants and animals. A species called Pseudomonas putida is widely used in oil spill decontamination or bioremediation.

Where is Pseudomonas putida found?

Pseudomonas putida is a Gram-negative bacterium found in water and soil, particularly in the rhizosphere at a relatively high population density (10). This microorganism has been studied extensively as a model for biodegradation of aromatic compounds such as naphthalene (11) and styrene (12, 13).

Which bacteria is called superbug that could clean oil spills?

In 1971, Prof. Chakrabarty got notable recognition for development of a genetically engineered Pseudomonas, “an oil eating bacteria” also known as “superbug” while working at General Electric Research and Development Center.

How was Pseudomonas putida produced?

In P. putida and most other bacteria, these precursors are produced from pyruvate and glyceraldehyde 3-phosphate by the methylerythritol 4-phosphate (MEP) pathway, whereas other bacteria synthesize the same precursors from acetyl-CoA using the unrelated mevalonate (MVA) pathway.

How does Pseudomonas putida CBB5 eat caffeine?

Pseudomonas putida CBB5 breaks caffeine into a carbon dioxide molecule and an ammonia molecule, according to Physorg. No other caffeine eating bacterium has previously been found.

Is pyocyanin a unique test for the identification of Pseudomonas aeruginosa?

Pseudomonas aeruginosa is the only gram-negative bacillus capable of producing the very distinctive water-soluble pigment pyocyanin. We evaluated the reliability of this characteristic as a unique test for the identification of this organism by using Tech agar (BBL Microbiology Systems, Cockeysville, Md.) medium.

What are the characteristics of Pseudomonas aeruginosa?

The most characteristic feature of Pseudomonas aeruginosa is the production of soluble pyocyanin pigment: a water soluble blue green phenazine compound. From the beginning, pyocyanin had been used as a reversible dye with a redox potential similar to that of menaquinone.

What is the role of PCN in the pathophysiology of Pseudomonas aeruginosa infection?

Despite in vitro studies demonstrating that PCN interferes with multiple cellular functions, its importance during clinical infection is uncertain. This is partially caused by the difficulty in defining the contribution of PCN among the numerous virulence factors produced by P. aeruginosa during infection.
