Pseudomonas putida strain KH-18-2

Pseudomonas putida strain KH-18-2 is a Gram-negative, mesophilic, rod-shaped bacterium that primarily inhabits soil and wastewater environments. As a heterotrophic organism, it derives its energy from organic compounds. The bacterium exists as single cells and exhibits mobility, facilitated by the presence of flagella. This strain is facultatively anaerobic, allowing it to thrive in both oxygen-rich and oxygen-poor conditions. Pseudomonas putida KH-18-2 possesses a double membrane structure and contains a single replicon, which is characteristic of many bacteria within the Pseudomonas genus. Pseudomonas putida KH-18-2 is known for its biotic relationships, being free-living and interacting with a diverse range of hosts. These hosts include various plant species such as Triticum aestivum (wheat), Solanum lycopersicum (tomato), and Oryza sativa (rice), as well as algae and even animals like Struthio camelus (ostrich) and the fungus Ophiostoma piceae. Despite its ecological versatility, Pseudomonas putida KH-18-2 is also associated with nosocomial infections, indicating its potential pathogenicity in animals, including humans. This dual role as both a beneficial environmental organism and a potential pathogen highlights the complex interactions within microbial communities and their varying impacts on ecological and human health.
