Citrobacter freundii str. c196

Citrobacter freundii strain c196 is a Gram-negative, rod-shaped bacterium that exhibits facultative anaerobic metabolism. This strain is nonsporulating and has been identified in a variety of environments, including hospital sewage, the intestinal tract, general sewage, soil, and surface waters. Its presence in diverse habitats suggests a versatile ecological role, allowing it to adapt to both anaerobic and aerobic conditions. The ability to thrive in hospital sewage indicates a potential association with human activity, while its isolation from natural environments such as soil and surface waters highlights its adaptability and resilience. The varied habitats of C. freundii str. c196 may reflect its role in nutrient cycling and organic matter decomposition within these ecosystems. Its adaptable nature may enable it to respond to environmental changes, potentially influencing microbial community dynamics in both clinical and natural settings. This strain's capacity to inhabit both anthropogenic and natural environments underscores its significance in understanding microbial ecology and the impacts of human waste on microbial populations in the environment.
