Pseudomonas fragi is a psychrophilic, Gram-negative bacterium that is responsible for dairy spoilage.[1] Unlike many other members of the genus Pseudomonas, P. fragi does not produce siderophores.[2] Optimal temperature for growth is 30 °C, however it can grow between 0 and 35 °C.[3] Based on 16S rRNA analysis, P. fragi has been placed in the P. chlororaphis group.[4]
