A double reciprocal plot was created from the specific growth rate and limiting-substrate concentration data obtained from a chemostat experiment. A linear regression gave values of 1.25 h and 100 mg hL-1 for the intercept and slope, respectively.
(a) The respective values of the Monod kinetic constants μm (h-1) and K. (mg L-¹) are as follows:

The same culture (with the m and K, values as computed above) is cultivated in a 10 L chemostat being operated with a 50 mL min-1 sterile feed containing 50 g L-1 of substrate. Assuming an overall yield coefficient of 0.3 (g- DCW) (g- substrate), the respective values of the outlet biomass and substrate concentrations are

Continuous stirred tank fermenter is characterized by (biomass concentration X kg/m3, residual substrate is S kg/m3, Sf=substrate concentration in feed kg/m3, Dilution rate = D and µm>>D and Km<Sf, XD= the biomass productivity kg/m3h. If the dilution rate is doubled to 2D then the new steady state values in comparison with earlier steady state is characterized by
