Identification of bacteria in a mixed culture
WebAll of these characteristics can help identify the bacteria. A few tests that microbiologists will perform are isolation, staining reactions, biochemical reactions, indole tests, Catalase test, Coagulase test, Oxidase test and many others. Purpose The purpose of this experiment is to be able to identify the bacterial unknowns in a mixed culture Webof three different bacterial species. You will attempt to identify the three bacterial species in this first week using several standard microbiology identification techniques. However, before you can attempt to identify the individual bacterial species, you will need to separate the bacteria in the mixed liquid culture from each other.
