Citrobacter freundii

Citrobacter freundii is a Gram-negative, rod-shaped bacterium characterized by the presence of true flagella and a facultative anaerobic metabolism. This microbe is nonsporulating, which indicates its inability to form spores as a survival mechanism under adverse conditions. C. freundii is typically found in diverse habitats, including hospital sewage, the intestinal tract of various hosts, general sewage, soil, and surface waters. The genomic architecture of C. freundii is notable, comprising ten replicons, which reflects its complex genetic organization and potential adaptability to various environments. The strain is represented by multiple genome accessions, underscoring the existence of various genomic sequences associated with this species. C. freundii's environmental versatility allows it to thrive in different niches, providing insight into its potential role in nutrient cycling and microbial community dynamics. Its presence in both clinical and environmental settings highlights its ecological significance and the need for further research to understand its interactions within microbial ecosystems.
