explain the possible factors affecting the growth of e.coli that results to no growth after doubling time.
Step by step
Solved in 3 steps
- 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 sugarExplain the results in detail for population growth of E.coli at various temperatures at different timesDifferentiate the growth curve exhibited by the same inoculum under the following conditions. Draw and label the parts of your growth curve. A). If it is exponentially growing and inoculated in the same nutritious medium under the same optimum conditions. B). If it is taken from an old culture and inoculated into the same nutritious medium and incubated under the same optimum conditions in (A). C). If it is taken from an old culture and inoculated to a different and less nutritious medium and incubated under the same optimum conditions as (A).
- Explain how an enzyme can be useful in treating a bacterialinfection, such as that which occurs with cystic fibrosis.TRUE OF FALSE: Is E coli colonies colorless in Eosin Methylene BlueAgar (EMBA)? Coliform colonies colorless in Eosin Methylene BlueAgar (EMBA)?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.
