Is ecoli citrate positive?

Escherichia coli (E. coli) is typically citrate negative, meaning it cannot utilize citrate as its sole carbon source. However, some strains of E. coli, particularly certain Enterobacteriaceae, may exhibit citrate positivity due to specific metabolic capabilities. In laboratory tests, E. coli is generally classified as citrate-negative in standard media such as Simmons' citrate agar.


Organism which is citrate positive indole negative MR negative VP negative sorbitol negative?

The organism is likely to be Escherichia coli. E. coli is citrate positive since it can utilize citrate as a carbon source, but it is indole negative as it does not produce indole from tryptophan. Additionally, E. coli is MR (methyl red) negative and VP (Voges-Proskauer) negative, indicating its fermentation pattern. Lastly, E. coli is typically sorbitol negative, meaning it does not ferment sorbitol.
