10. Dynamics of Microbial Growth

The time between inoculation and the beginning of growth in a microbial culture is referred to as:

The log phase of the bacterial growth curve is marked by

In the growth curve of a bacterial population, the bacteria are rapidly increasing in number during the:

Rates of cell production and cell death are approximately equal during the _____ phase of microbial growth.

In a rapidly multiplying bacterial population, cell numbers increase

Which bacterial culture will have the highest growth rate?

Seven methods of measuring microbial growth were explained in this chapter. Categorize each as either a direct or an indirect method.

DRAW IT Label the trophophase and idiophase in this graph. Indicate when primary and secondary metabolites are formed.

Match the term to the proper description(s). A term can have more than one description. <IMAGE>

Which of the following is most useful in representing population growth on a graph?

a. logarithmic reproduction of the growth curve

b. a semilogarithmic graph using a log scale on the y-axis

c. an arithmetic graph of the lag phase followed by a logarithmic section for the log, stationary, and death phases

d. None of the above would best represent a population growth curve.

Draw and label the four distinct phases of a bacterial growth curve. Describe what is happening within the culture as it passes through the phases.

What is the difference between growth and reproduction?
