Most E. coli (about 97%) produce beta-glucuronidase which produces a blue precipitate associated with the colony indicated by the blue to red-blue colonies. The top film traps gas produced by the lactose fermenting coliforms and E. coli. About 95% of E. coli produce gas, as indicated by colonies associated with entrapped (D) Colony morphology at 37°C and 22°C of co969 and co969 ΔVC2744 carrying either pHL100-bipA, for overexpression of V. cholerae co969 VC2744 from the isopropyl-β-d-thiogalactosidase-inducible Plac promoter, pHL100-ECbipA; or pHL100-PPbipA, for overexpression of the bipA variants of Escherichia coli MG1655 K-12 or Pseudomonas putida KT2440, respectively, or the empty plasmid (pHL100).

Passing result: E. coli should appear as pink to red colonies. Describe features of colonies. See variations in colonial morphology among various species of bacteria. Bacteria grow on solid media as colonies. A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike. The shape of E.coli colonies in nutrient agar is circular while in blood agar is irregular.

For the purposes of this evaluation, pink and purple/blue colonies were also selected for confirmation and inoculated into EC‐MUG broth. Enterotoxigenic Escherichia coli, or ETEC, is the name given to a group of E. coli that produce special toxins which stimulate the lining of the intestines causing them to secrete excessive fluid, thus producing diarrhea.
