Pseudomonas putida strain MC4-5222

Pseudomonas putida strain MC4-5222 is a Gram-negative, rod-shaped bacterium that primarily inhabits soil and wastewater environments. This strain is heterotrophic, utilizing organic compounds as its energy source, and exhibits facultative anaerobic metabolism, allowing it to thrive in both aerobic and anaerobic conditions. P. putida MC4-5222 is motile, possessing flagella that facilitate its movement. The strain has a mesophilic temperature range, indicating optimal growth at moderate temperatures. It is characterized by a single replicon and possesses two membranes, typical of Gram-negative bacteria. P. putida MC4-5222 is free-living and has been associated with a diverse array of biological hosts, including various plants (e.g., Triticum aestivum, Solanum lycopersicum, Oryza sativa) and even animals (e.g., Homo sapiens, Struthio camelus). While this strain is not known to sporulate, it has been implicated in nosocomial infections, suggesting a potential pathogenic relationship with animal hosts. Its ability to thrive in various ecological niches and its interactions with a wide range of hosts emphasize the ecological versatility of Pseudomonas putida. This adaptability not only highlights its role in natural soil and wastewater ecosystems but also raises concerns regarding its presence in clinical settings, where it may contribute to health complications. The strain's varied interactions with both plant and animal life illustrate the complex dynamics of microbial life and its implications for health and disease.
