1. Why do variations in generation time exist?
a. Among different species of microorganisms?
b. Within a single microbial species?
2. What do you predict would happen to the shape of the growth curve if you were to subculture vibrio growing in log phase rich medium into a poor growth medium? Draw a diagram showing your answer.
3. The generation time and growth rate of an organism grown in the laboratory can be easily determined by constructing a typical growth curve. Would you expect the growth rate of the infectious organisms found in an abscess that developed from a wound to mimic the growth curve obtained in the laboratory?
4. Is generation time a useful parameter to indicate the types of media best suited to support the growth of a specific organism?
