5. True. All the members of Enterobacteriaceae are gram-negative. So they give the oxidase test negative. Oxidase test is used to determine whether an organism performs aerobic or anaerobic respiration.
6. True. As with the fresh medium, the test gives accurate results as the oxidase test uses the enzyme cytochrome c to identify oxygen receptor chains.It works best when the culture is fresh and the loop is also fresh and sterilized properly.
7. True. Oxidase test gives positive results when the color changes to blue/purple in the medium. This means that bacteria are aerobic.

You have been given another unknown and the Gram stain results revealed Gram positive rods. Your TA now tells you that you should inoculate your unknown into a TSB broth to be incubated at 65 degrees C for 24 hr. and to streak it onto a TSA plate for isolation. The TSA plate is incubated at 35-37 degrees C for 24 hr. It will then be used to do further inoculations of your...
