The appearance of E. coli will vary depending on what type of agar you used. But I assume you have used a standard nutrient agar type of medium. In that case E. coli colonies will look like pale yellow, round, smooth colonies.Well, at least that is how laboratory strains of E. coli will look.he appearance of E. coli will vary depending on what type of agar you used.

Escherichia coli, more commonly known as E. coli, is a group of bacteria that populate the human (and animal) gut. E. coli is usually thought of as a good bacterium; it lives in the intestines as part of the normal gut flora.. However, some strains of E. coli can cause very serious illness. These disease-causing (virulent) strains are usually classified by the action they have on the gut; these strains include enterohemorrhagic (called EHEC), enteropathogenic (called EPEC), enteroinvasive (called EIEC), and enterotoxigenic (ETEC).
