The main difference between Pseudomonas Aeruginosa and Pseudomonas Putida is that P. Aeruginosa is a disease-causing microorganism whereas P. putida is a saprophytic soil bacterium.
P. aeruginosa and P. putida are two types of Pseudomonas species that belong to the Family Pseudomonadaceae. Both are Gram-negative, rod-shaped bacteria.

What is Pseudomonas Aeruginosa
P. aeruginosa is an encapsulated bacterium that is Gram-negative. It is an aerobic or facultative anaerobic bacterium. More importantly, P. aeruginosa is a disease-causing bacterium in plants, animals, and humans. It is also a multidrug-resistant pathogen. In general, it causes hospital-acquired infections such as ventilator-associated pneumonia and various sepsis syndromes. Normally, P. aeruginosa is an opportunistic pathogen that causes serious infections during existing disease conditions. In addition, it affects immunocompromised individuals. However, it is difficult to treat P. aeruginosa infections as the bacteria is multidrug-resistant.

Furthermore, P. aeruginosa lives in soil, water, skin flora, and most man-made environments. Generally, it is an aerobic bacterium that thrives in the normal atmosphere. It can tolerate low oxygen atmospheres as well. Its versatility allows the bacterium to infect damaged tissues as well as individuals with reduced immunity. Inflammation and sepsis are the generalized symptoms of P. aeruginosa infections. It can be fatal when the bacterial infection is in the lungs, the urinary tract, and kidneys. Because it thrives on moist surfaces, this bacterium is also found on and in medical equipment, including catheters, causing cross-infections in hospitals and clinics. However, the bacterial infection of P. aeruginosa is less virulent in comparison to Gram-positive Staphylococcus aureus and Streptococcus pyogenes.
What is Pseudomonas Putida
P. putida is a Gram-negative, rod-shaped bacterium that is saprophytic. More importantly, P. putida is capable of undergoing bioremediation of environmental pollutants. Generally, the wild-type strains of P. putida are capable of bioremediating the soil inoculant to remedy naphthalene-contaminated soils. P. putida is capable of converting styrene oil into biodegradable plastic PHA. This is due to the effective recycling of the polystyrene form. However, it is the first patented organism in the world.

Moreover, the diverse metabolism of the P. putida species allows the bioremediation of different organic sources taking into account their energy source. Bioremediation is the degradation of environmental pollutants by the use of microorganisms.
Similarities Between Pseudomonas Aeruginosa and Pseudomonas Putida
- P. aeruginosa and P. Putida are two types of Pseudomonas species of the Family Pseudomonadaceae.
- Both are Gram-negative, rod-shaped bacteria.
- They are aerobic, non-spore-forming, catalase-positive, and oxidase-positive bacteria.
- One or more flagellum provides them motility.
Difference Between Pseudomonas Aeruginosa and Pseudomonas Putida
Definition
P. aeruginosa refers to a common encapsulated, Gram-negative, aerobic–facultatively anaerobic, rod-shaped bacterium that can cause disease in plants and animals, including humans while P. putida refers to a Gram-negative, rod-shaped, saprotrophic soil bacterium.
Habitat
Usually, P. aeruginosa lives in the soil, water, and skin flora while P. putida lives in the soil and water.
Pathogenicity
P. aeruginosa can cause diseases in plants, animals, and humans, while P. putida is a saprophytic bacterium that is rarely pathogenic.
Importance
P. aeruginosa causes hospital-acquired infections while P. putida is important in bioremediation.
Conclusion
In brief, P. aeruginosa and P. putida are two species of the genus Pseudomonas. Both are Gram-negative, rod-shaped bacteria. Both bacteria live in the soil and water. heyY are aerobic bacteria. P. aeruginosa lives in skin flora and it causes diseases in plants, animals, and humans. However, P. putida is a saprophytic bacterium. Therefore, the main difference between P. aeruginosa and P. putida is their pathogenicity.
