During which phase of the microbial growth cycle are cells most metabolically active and dividing at a constant maximum rate?

#Question id: 40188

#Applied Microbiology

Match the growth phase in Column A with its correct characteristic in Column B.

Column A (Phase)	Column B (Characteristic)
1. Lag Phase	A. Exponential decrease in the number of living cells.
2. Log Phase	B. Adaptation to new environment; synthesis of enzymes.
3. Stationary Phase	C. Nutrient depletion leads to equal rates of growth and death.
4. Death Phase	D. Uniform and rapid cell division; population doubles.

Read the following statements regarding the bacterial growth curve and choose the correct option.

Statement I: In the Lag phase, there is an immediate increase in the cell number as bacteria start dividing instantly.

Statement II: Secondary metabolites (like antibiotics) are predominantly produced during the Stationary phase.
