Two important members of the Enterobacteriaceae family are Escherichia coli and Enterobacter aerogenes . Both can be differentiated on the basis of IMViC test. Enterobacter species are able to utilize sodium citrate as the sole carbon source while E. coli fail to do so. You can get the answers you need here. The best, most helpful solutions are offered without charge.

Is Enterobacter aerogenes citrate positive or negative?
Klebsiella aerogenes, previously known as Enterobacter aerogenes, is a Gram-negative, oxidase negative, catalase positive, citrate positive, indole negative, rod-shaped bacterium. The bacterium is approximately 1-3 microns in length, and is capable of motility via peritrichous flagella. -

Result Interpretation of Citrate Utilization Test Positive Reaction: Growth with color change from green to intense blue along the slant. Examples: Salmonella, Edwardsiella, Citrobacter, Klebsiella, Enterobacter, Serratia, Providencia, etc. Negative Reaction: No growth and No color change; Slant remains green -

Citrate Utilization Test- Principle, Media, Procedure and Result
- Summary: Citrate Utilization Test- Principle, Media, Procedure and ResultThis test is among a suite of IMViC Tests (Indole, Methyl-Red, Vogues-Proskauer, and Citrate) that are used to differentiate among the Gram-Negative bacilli in the family Enterobacteriaceae.Citrate agar is used to test an organism’s ability to utilize citrate as a source of energy. The medium contains citrate as the sole carbon source and inorganic ammonium salts (NH4H2PO4) as the sole source of nitrogen.Bacteria that can grow on this medium produce an enzyme, citrate-permease, capable of…
