Question 9

A standard growth curve for a population of yeast cells of a single species in a closed batch culture includes a stationary phase.

Which option describes the characteristics of the stationary phase?

Interspecific competition for nutrients, such as glucose, reaches its peak.

The rate of cell division equals the rate of cell death as resources become limiting.

The accumulation of toxic metabolites, such as ethanol, causes the death rate to far exceed the division rate.

Logarithmic growth occurs at its maximum rate because there is no competition for space.
