Yes. EMBA is a differential media for E.coli. E.coli will grow as dark blue/ purple colonies with green metallic sheen. Sometimes the green metallic sheen is more difficult to identify if you only are allotted a certain time to check results. Sometimes the presence of the green metallic sheen is for a fleeting time. Evidence of the green metallic sheen will be a glossy sheen to the inoculation streak. diana
