Posted 26 April 2009 - 10:24 PM
Does anyone having idea that E.coli culture can give slight yellowish colonies on Macckonkey agar . I havent seen such type of colonies in past. Presently I am trying to demonstrate purity of one of the E. coli culture. All other test like Indole test is showing E. coli , but on Macconkey few colonies are yellowish. Does anyone has idea about this. Your suggestions and observations are necessary to come out with conclusion.
