Bacterial Growth Phases

Lag, Exponential, Stationary, and Death Phases with Nutrient Limitation

Phase: LAG
Generation: 0
Population: 0
Nutrients: 100%
Growth Rate: 0.00
Dead Cells: 0

Bacterial Growth Curve

Lag Phase: Cells adapt to new environment, synthesize enzymes.
Exponential: Rapid binary fission with constant doubling time.
Stationary: Growth = death due to nutrient depletion.
Death Phase: Cell death exceeds division, population declines.
