FOLLOW UP QUESTIONS: a 1. For each test, prepare a flash card with the following information (or you could create a single table and fill in the table for all tests): a. Name of the test b. Purpose of the test (enzymes present/absent, what you learn about the bacetria from doing the test) c. Colored sketch of positive result and negative result; note final pH where applicable d. Names of indicators (if applicable) and key reagents c. Other important details (e.g. reversion may occur, check results after 24 hours) 2. Distinguish between fermentation tests and respiration tests in terms of what each category of test tells you about the microbes you are studying. 3. Sketch a labeled, colored flow diagram for the nitrate test procedure, including results at each step and how to interpret the results. 4. In a situation similar to the practicum, what would you look for to state that a particular test is positive for mannose fermentation? Describe in detail. 5. In a situation similar to the practicum, what would you look for to state that a particular microbe is both oxidative and fermentative Describe in detail. 12, SP 16
6. Identify two methods for determining whether bacteria exhibit motility. Why might organisms that are normally motile display a loss of motility (under what circumstances)? 7. Distinguish motility from Brownian motion, as observed with a microscope. 8. Sketch both a positive and a negative motility stab. 9. Describe how motility can be an important factor in causing disease. 13, SP 16
