Question

For a culture, \( \mu_{max}=0.8~h^{-1} \) and \( K_s=0.2~g/L \). At substrate concentration \( S=0.2~g/L \), \( \mu \) is

• A. \(0.2~h^{-1}\)
• B. \(0.4~h^{-1}\)
• C. \(0.6~h^{-1}\)
• D. \(0.8~h^{-1}\)

Hint:

Remember this important Monod relationship: \[ \boxed{ S=K_s \Longrightarrow \mu=\frac{\mu_{max}}{2} } \] Whenever the substrate concentration equals the half-saturation constant, the microorganism grows at half of its maximum growth rate.

Answer 1

The Correct Option is B
