Citrobacter is a genus of gram-negative bacteria in the Enterobacteriaceae family.

The species C. amalonaticus, C. koseri, and C. freundii use solely citrate as a carbon source. These bacteria can be found almost everywhere in soil, water, wastewater, etc. It can also be found in the human intestine. They are rarely the source of illnesses, except for infections of the urinary tract and infant meningitis.

Citrobacter shows the ability to accumulate uranium by building phosphate complexes.^[1]
