General MicrobiologyThe IMViC test series is used to differentiate members of the Enterobacteriaceae family, including E. coli. E. coli typically has an indole positive (indole is produced when tryptophan is metabolized), methyl red positive (indicating the ability to ferment glucose and produce acid), Voges-Proskauer positive (produces acetoin from glucose), and citrate negative (does not utilize citrate as a sole carbon source) biochemical profile. This profile helps distinguish it from other related bacteria like Proteus and Klebsiella species.
