Citrobacter freundii strain 18-1

Citrobacter freundii strain 18-1 is a Gram-negative, rod-shaped bacterium that is classified as a facultative anaerobe and is nonsporulating. This strain is typically found in diverse habitats, including hospital sewage, the intestinal tract, various sewage environments, soil, and surface waters. The ability of C. freundii strain 18-1 to thrive in both aerobic and anaerobic conditions allows it to occupy various ecological niches, adapting to fluctuating oxygen levels commonly encountered in its environments. Given its presence in hospital sewage and the intestinal tract, C. freundii strain 18-1 may play a role in microbial communities associated with human health and environmental sanitation. The strain's adaptability to diverse habitats suggests that it may engage in complex interactions with other microorganisms, potentially influencing nutrient cycling and organic matter decomposition in its ecosystems. This characteristic highlights the importance of C. freundii strain 18-1 in both clinical and environmental contexts, where it may contribute to the maintenance of microbial diversity and stability.
