. What is a typical pattern of growth of a bacterial population?
- An exponential phase followed by a stasis phase.
- A lag phase, followed by the log phase, followed by a stationary phase.
- An exponential phase followed by a slow-growth phase.
- An exponential phase, followed by a decline phase.
- A lag phase, followed by a stationary phase, followed by the log phase\
Homework Answers
The correct answer is - B-
Explanation- The bacterial growth kinetics shows 4 stages- the
lag phase(when the bacteria divides very less and also are less in
number), followed by log phase(where the bacteria has all become
very active
and starts dividing by binary fission vigorously), followed by
stationary phase(when the bacteria divide, but they also die-such
that the death rate and division rate are same) and finally death
phase(the bacterial population decreases--due to the accumulation
of toxic products in the medium).

a. Write down a differential equation for bacterial growth during the exponential phase (batch culture), where k is the instantaneous growth rate. b. Solve the equation. Your solution should be a continuous function that gives the number of cells as a function of time. c. Write an equation for the doubling time (generation time) in terms of k. d. Parameterize your equation as follows: Assume that you start with 10 cells, and that it takes each cell 30 minutes to...

a) During the exponential phase of bacterial growth, the lab strain of E. coli has doubling time of about 30 minutes. If you start with 10,000 cells per mL of culture, and let them grow exponentially 2 hours in a flask, what is the final density of the culture? Show and explain your calculations. b) If you plated a100μL of 1:1000 dilution that culture (after it had grown in a flask for 2 hrs) how many colonies would you expect...
