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.
