Citrobacter is a genus of Gram-negative coliform bacteria in the Enterobacteriaceae family.
The species C. amalonaticus, C. koseri, and C. freundii can use citrate as a sole carbon source. Citrobacter species are differentiated by their ability to convert tryptophan to indole (C. koseri is the only citrobacter to be commonly indole-positive), ferment lactose (C. koseri is a non-lactose fermentor), and use malonate.
Citrobacter shows the ability to accumulate uranium by building phosphate complexes.
These bacteria can be found almost everywhere in soil, water, wastewater, etc. They 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 and sepsis.
