🧮 Cell Growth Formulas
📊 Typical Doubling Times
| Organism | Doubling Time |
|---|---|
| E. coli (optimal) | 20 minutes |
| Yeast (S. cerevisiae) | 90-120 minutes |
| HeLa cells | 24 hours |
| Primary mammalian cells | 24-48 hours |
| M. tuberculosis | 15-20 hours |
📈 Growth Phases
- Lag Phase: Cells adapt to new environment, minimal division
- Log/Exponential Phase: Rapid, constant growth rate (this calculator assumes)
- Stationary Phase: Growth slows due to nutrient depletion
- Death Phase: Cell death exceeds division
❓ FAQ
When should I take measurements?
Take measurements during the exponential/log phase for accurate growth rate calculations. Lag and stationary phases don't follow exponential kinetics.
What affects doubling time?
Temperature, nutrients, pH, oxygen levels, and cell density all affect growth rate. Optimal conditions give the shortest doubling time.
