Citrobacter freundii strain AR_0116

Citrobacter freundii strain AR_0116 is a Gram-negative, nonsporulating rod-shaped bacterium that exhibits facultative anaerobic metabolism. This strain is part of a diverse group of bacteria commonly found in various environments, including hospital sewage, the intestinal tract of humans and animals, as well as in soil and surface waters. As a facultative anaerobe, C. freundii strain AR_0116 can grow in both aerobic and anaerobic conditions, allowing it to thrive in the variable oxygen environments characteristic of its habitats. Its presence in hospital sewage highlights its potential association with human activities and waste management systems, while its occurrence in soil and surface waters suggests a broader ecological role. The adaptability of C. freundii strain AR_0116 to different environments may contribute to its survival and persistence in diverse ecological niches. This adaptability could facilitate its interactions with other microbial communities, potentially influencing nutrient cycling and the degradation of organic matter in its habitats. Further exploration of its ecological roles could provide insights into the dynamics of microbial communities in environments impacted by human activity.
