Pseudomonas putida- An Overview


Pseudomonas putida is a Gram-negative, rod-shaped, saprophytic soil bacterium that belongs to the fluorescent group of Pseudomonas species . It is widely distributed in various ecological habitats, such as soil, water, plants, animals, and human beings. It has a versatile metabolism and can degrade a wide range of organic compounds, including aromatic hydrocarbons, alcohols, sugars, and amino acids. It can also produce different forms of fluorescent pigments, such as pyoverdine and pyoluteorin.

Pseudomonas putida is generally considered a non-pathogenic bacterium that rarely causes infections in humans . However, some strains of P. putida can act as opportunistic pathogens in immunocompromised individuals, such as newborns, cancer patients, and people with cystic fibrosis or AIDS . The common sites of infection include the bloodstream, skin, soft tissues, and lungs . The infections can be serious and life-threatening if not treated promptly and appropriately .

Pseudomonas putida was first described by Trevisan in 1889. The genus name `putida` is derived from the Latin term `putida`, meaning stinking or fetid, indicating the occurrence of the bacteria in spoiled food items and the aromatic odor on solid media. Pseudomonas putida is considered an evolutionary group that includes several other species based on the common 16S rRNA sequences. P. putida is further classified into two biovars; biovar A and biovar B.

Pseudomonas putida is one of the most studied and exploited bacteria in biotechnology and bioremediation. It has the ability to decompose various pollutants, such as oil spills, pesticides, herbicides, and heavy metals. It can also produce useful compounds, such as biodegradable plastics, antibiotics, enzymes, and biosurfactants. Moreover, it can be used as a biocontrol agent to protect plants from pathogenic microorganisms.

Pseudomonas putida is a remarkable bacterium that has a great potential for environmental and industrial applications. It is also a model organism for studying bacterial physiology, genetics, and evolution. In this article, we will provide an overview of the classification, habitat, morphology, cultural characteristics, biochemical characteristics, virulence factors, pathogenesis, clinical manifestation, lab diagnosis, treatment, prevention, and industrial uses of Pseudomonas putida.
