Study Notes
Microbial Growth Curve
- During the lag phase, microbial cells prepare to enter into the active growth phase.
Exponential Phase
- Cell growth occurs at a constant rate during this phase.
Stationary Phase
- The cessation of cell growth in the stationary phase is led by the depletion of nutrients and accumulation of waste products.
- Starving bacteria produce Dps proteins that protect DNA in the stationary phase.
- The production of Dps proteins makes starving bacteria more resistant to damage in the stationary phase.
