Microbiology
1. What are the principles in the use of TZCA (Tetrazolium Chloride agar), YDCA (Yeast Dextrose Carbonate agar), and KMBA (King's Medium B agar) in describing cultural characteristics of bacteria?
2. List down three other media with their uses in describing the cultural characteristics of bacteria.
3. Why do some microorganisms characteristically form growth of the pellicle type in nutrient broth?
4. What environmental factors may alter formation of a pellicle?
5. What is the importance of using a test/ control organism in describing the cultural characteristics of an unknown bacterium?
This is for an exercise about cultural characteristics of bacteria controls:
Staphylococcus aureus in Nutrient agar
Pseudomonas aeruginosa in King's Medium B agar
Serratia marcescens in Tetrazolium Chloride agar
Micrococcus luteus in Yeast Dextrose Carbonate agar
