1. How is actual motility of the bacteria distinguished from a wobble of the needle/loop when interpreting the motility portion of the SIM medium test?
2. What is the black precipitate in a positive sulfur reduction result in SIM medium? What two enzymes might be responsible for the sulfur reduction?
3. What does the Kovac’s reagent react with in a positive reaction? What molecule is broken down to create this product? What enzyme did these bacteria produce?
4. What is the cell using for nutrients if it does gamma hemolysis? Obviously since the red blood cells are not damaged, they are not the nutrient source. Agar is not a nutrient source, agar just makes the medium firm.
5. Blood agar is useful for detecting what general kinds of organisms (other than beta-hemolytic, etc.)? Name a species that might be traditionally detected/identified by its appearance on blood agar.
6. Why do we not allow you to culture from your throat in this exercise?
