Flashcards
Log (Exponential) Phase
Log (Exponential) Phase
The phase of bacterial growth where the population increases exponentially, resulting in a straight line on a log plot.
Stationary Phase
Stationary Phase
The stage of bacterial growth where the rate of cell division equals the rate of cell death, resulting in a stable population size.
Bacterial Sensitivity in Log Phase
Bacterial Sensitivity in Log Phase
During the log phase, bacteria are most sensitive to conditions that interfere with their growth process.
