1. Define bacterial growth curve? Explain the different phases of growth of bacteria?
2. Define the following terms:
a. Growth rate constant
b. Generation time.
3. A bacterium increases its number from 5 X 103 cells/ml to 2 X 108 cells/ml in 10 hours. Calculate the mean generation time?
4. A student is performing bacterial growth curve experiment. At time t = 0 hours, he inoculated 50 ml of the favorable growth medium with 100 bacterial cells. After six hours, the bacterial population was around 450 CFU/ 50 ml bacteria. Calculate the growth constant "k" for the bacteria?
5. A typical bacterial cell increases from one cell to 512 cells in 10 hours. What is the generation time of this bacterium?
