Citrobacter freundii strain GEO_16_Eff_A

Citrobacter freundii strain GEO_16_Eff_A is a Gram-negative, nonsporulating rod-shaped bacterium that exhibits facultative anaerobic metabolism. This strain has been isolated from diverse environments, including hospital sewage, intestinal tracts, sewage systems, soil, and surface waters, indicating its adaptability to various ecological niches. As a facultative anaerobe, Citrobacter freundii strain GEO_16_Eff_A can thrive in both aerobic and anaerobic conditions, allowing it to exploit a range of substrates for growth depending on the availability of oxygen. Its presence in hospital sewage and surface waters suggests it may play a role in nutrient cycling, particularly in environments impacted by human activity. The ability of this strain to inhabit complex environments like sewage and soil highlights its potential involvement in biogeochemical processes and its interaction with other microbial communities. Understanding the ecological roles of Citrobacter freundii in such varied habitats could provide insights into microbial dynamics and the impact of anthropogenic influences on microbial diversity and function in aquatic and terrestrial ecosystems.
