To identify your unknown start at the beginning of the corresponding Dichotomous Key. Answer the tests step-by step.. For example, the identification of all gram-negative unknowns starts with the Oxidase test: Is your unknown Oxidase positive or negative? Depending on the result continue with the next test, until you reach a point at which you will obtain the name of one bacterial species. This is your gram-negative unknown.
