What are the differences between the
To describe: The difference between the lag phase and the log phase of a bacterial growth curve.
Introduction: The bacteria is the unicellular prokaryotic organism that maintains a definite shape since it contains the rigid cell wall. It is classified into different types based on the structure namely coccus (spherical shaped), Bacillus (rod-shaped), filamentous, spirilla (spiral-shaped), appendaged and pleomorphic bacteria. The structure of the bacteria can be viewed under the microscope by using the staining methods.
Explanation of Solution

- Why does a one-step growth curve differ in shapefrom that of a bacterial growth curve?arrow_forwardWhat 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.arrow_forwardAre you able to identify the lag, log, stationary and death phase in using these growth curves?Are you able to calculate the generation time for this microbe under the two conditions?arrow_forward
- Describe the following phases of the bacterial growth curve and draw them out:a. Lag phaseb. Logarithmic phasec. Stationary phased. Decline/death phasearrow_forwardHow do we calculate the generation time of a bacterial culture that increases in population of 104 to 1012 cells in 15 hours ?arrow_forwardList and define the four phases of growth in a bacterial growth curve.arrow_forward
- Are you able to identify the lag, log, stationary and death phase in using this growth curve? Are you able to calculate the generation time for the microbial under this condition?arrow_forwardWhat method of bacterial measurement does this graph represent? Is it considered direct, or indirect? What phase of the growth curve can NOT be measured using this method?arrow_forwardIf the generation time is 90 min and the initial population contains 103 cells, how many bacteria will there be after 8 hours of exponential growth?arrow_forward
- What type of overall bacterial growth does the following graph represent? aggregated logistic differential exponentialarrow_forwardHow might the bacterial growth curve change if a facultative anaerobe was first monitored for growth when grown in the presence of an O2 environment and, during its log (exponential) growth phase, the organism was suddenly placed in an anaerobic environment?arrow_forwardCompare and contrast the four phases of growth in a bacterial growth curve.arrow_forward
