Pseudomonas fluorescens strain 48D1

Pseudomonas fluorescens strain 48D1 is a Gram-negative, rod-shaped bacterium that thrives as a heterotroph in various habitats. This organism is aerobe, requiring oxygen for growth, and exhibits mobility due to the presence of flagella. It is classified as mesophilic, with an optimal growth temperature of 25°C, and has a single replicon and a double membrane structure. Strain 48D1 is free-living and engages in biotic relationships with a diverse range of hosts, including Homo sapiens, various Metazoa, and multiple plant species such as Triticum aestivum (wheat), Solanum tuberosum (potato), and Solanum lycopersicum (tomato). It is also associated with several amphibian species and various plants, indicating its ecological versatility. Despite its beneficial roles in the environment, Pseudomonas fluorescens strain 48D1 is known to be associated with bacterial infections in animals, suggesting a pathogenicity potential. This characteristic emphasizes the importance of understanding the ecological roles and health implications of Pseudomonas fluorescens strains, particularly in contexts where they interact with both plant and animal hosts. The strain's diverse host range and free-living nature highlight its ecological significance, as it may play a role in nutrient cycling and microbial interactions within various ecosystems.
