A continuous culture is maintained under steady-state conditions in a chemostat where the dilution rate equals the specific growth rate. If the maximum specific growth rate (μmax) of the organism is 0.8 h^-1 and the substrate concentration at which the organism grows at this rate is 1.6 g/L, determine the substrate concentration (in g/L) at which the specific growth rate becomes 0.4 h^-1. Assume Monod kinetics apply and Ks=0.4 g/L.

In a chemostat experiment, a microbial species with 𝜇_max=1.0 h⁻¹  and 𝐾𝑠=0.2 g/L is maintained at steady-state. If the dilution rate is set to 0.5 h^-1, calculate the substrate concentration (S) in the reactor (in g/L), assuming Monod growth.
