In a batch culture, the initial bacterial count is \(N_0 = 1.0 \times 10^{3}\) cells. After 6 h, the population under Condition A reaches \(N_A = 8.0 \times 10^{5}\) cells, whereas under Condition B it reaches \(N_B = 2.0 \times 10^{5}\) cells. Assuming exponential growth, the number of generations \(g\) in time \(t\) satisfies \(N = N_0 \times 2^{t/g}\). Determine the generation time (in hours) for each condition and indicate which condition supports faster bacterial growth.

Answer Options

Correct Answer A. Condition A: generation time ≈ 0.62 h; Condition B: generation time ≈ 0.79 h. Condition A grows faster.
B. Condition A: generation time ≈ 0.75 h; Condition B: generation time ≈ 0.62 h. Condition B grows faster.
C. Condition A: generation time ≈ 0.62 h; Condition B: generation time ≈ 0.79 h. Both conditions grow at the same rate.
D. Condition A: generation time ≈ 0.55 h; Condition B: generation time ≈ 0.90 h. Condition A grows faster.
Correct Answer
A
Correct Option:
Condition A: generation time ≈ 0.62 h; Condition B: generation time ≈ 0.79 h. Condition A grows faster.
