Question
  1. missing a name or two from the list (Enterobacter aerogenes), and (Serratia rubidaea) - should be 20
  2. Proteus Vulgaris (spelling) is eliminated under citrate so you can't have it at the end.
  3. Which test MR or VP - not both


some of the above choices are strict aerobes and some are facultative anaerobes. This is helpful to first eliminate a set from your possibilities (look them up to figure this out)

At first eliminate the organisms that *cannot* do something your organism *can*. This means you have a positive test result and you eliminate those that are always negative for that result. That way you do not have to worry that you accidentally killed the unknown before you inoculated it. You Do still need to be concerned that you interpreted the test results correctly and did not introduce a contaminant that has the ability you were testing while your true unknown did not.
