Step by step
Solved in 2 steps
- Describe each phase of the BACTERIAL GROWTH CURVE (explain what happens, give the cells characteristics…).Plot the bacterial growth curve. (Plot in an understandable and neat way)b. The growth rate of a certain species of bacteria is being modelled to determine the number of bacteria after certain period of time. The growth rate is proportional to the number of bacterial present. Assess the growth process and state the model equation that can be used.
- 4) Draw a typical bacterial growth curve. Label the stages of growth and the axis of the graph.Describe the events that occur with E. coli in each of the following growth conditions: in a medium containing glucose but not lactose; in a medium containing both sugars; in a medium containing lactose but no glucose; and in a medium containing neither sugarName two methods of control of growth for Mycobacterium tuberculosis pathogen in a patient with the disease and when confronted with the pathogen outside of the host. Be careful to specify if it is a physical method or a chemical method (check lecture to differentiate these two). Control of growth means how would you deal with an infection related to a person as well as how would you minimize the presence of the bacteria on a surface or object.
- Describe the following phases of the bacterial growth curve and draw them out:a. Lag phaseb. Logarithmic phasec. Stationary phased. Decline/death phaseBacterial cells are most likely to be affected by antibiotics when they are in this phase of the bacterial growth curve.Make a brief summary of each of the stages of bacterial growth.
- Describe the bacterial colonies providing information on shape, color, size, elevation and edge appearance.Why does a one-step growth curve differ in shapefrom that of a bacterial growth curve?What are the defining characteristics of the exponential/log phase of the bacterial growth curve. Explain the culture conditions that arise that cause the phase to end. In different culture media, and the exact same starting inoculum, will the end of exponential/log occur at the same time? Why or why not? A graph or a drawing of the growth curve would help but is not essential to answer this question.
