value of Ks?
1. The Monod equation is a mathematical model for the growth of microorganisms. K, (half saturation constant) is the substrate concentration at which half of the maximum specific growth rate is reached. Using the Monod equation, the growth rates as a function of substrate concentration are plotted for three microorganisms (A, B, and C) as below. Which microorganism has the lowest value of Ks? I II III IV μm S -Microbe A μ Ks + S ----Microbe B ........ Microbe C where μm = maximum specific growth rate, d-¹ S = concentration of rate limiting substrate, mg/L Ks = half saturation constant, mg/L 10 20 30 50 = concentration of limiting substrate when μ = 0.5 μm Limiting substrate concentration, S, mgBOD;/L (A) Microbe A (B) Microbe B (C) Microbe C (D) None of above Growth rate constant, μ, d-¹ 40
