Pseudomonas putida strain DLL-E4

Pseudomonas putida strain DLL-E4 is a Gram-negative, rod-shaped bacterium primarily found in soil and wastewater environments. It is classified as a heterotroph, relying on organic compounds for energy. This strain exhibits a facultative oxygen requirement, allowing it to thrive in both aerobic and anaerobic conditions. DLL-E4 possesses mobility, facilitated by the presence of flagella, and it typically exists as single cells. With a mesophilic temperature range, Pseudomonas putida strain DLL-E4 can adapt to moderate temperature fluctuations common in its natural habitats. It has a simple genetic structure characterized by a single replicon and is bounded by two membranes, typical of Gram-negative bacteria. Strain DLL-E4 does not produce spores, which is consistent with its ecological niche. The strain has demonstrated various interactions with a wide range of hosts, including plants such as Triticum aestivum (wheat), Solanum lycopersicum (tomato), and Oryza sativa (rice), as well as other organisms like Chlamydomonas reinhardtii and Struthio camelus. However, it is noteworthy that Pseudomonas putida strain DLL-E4 is also associated with nosocomial infections in humans, indicating its potential pathogenicity in animal hosts. The ecological significance of this strain lies in its ability to thrive in diverse environments while engaging in complex interactions with both flora and fauna. Its role as a free-living bacterium in soil and wastewater systems may contribute to nutrient cycling and the health of these ecosystems, highlighting its importance in environmental microbiology.
