The growth of bacteria to form a product, P, is carried out in a 25 dm² CSTR. The bacteria consume the nutrient substrate to generate more cells and the desired product: Substrate → More Cells + Product, catalyzed by cells currently in the system The CSTR was initially inoculated with bacteria and now has reached steady state. Only substrate (nutrient) is fed to the reactor at a volumetric crate of 5 dm³/h and a concentration of 30 g/dm³. The growth law of the cells, rg (grams cells / (h dm³)), is expressed as: Hmax CsCc Km + Cs Where µmar = 0.5hr" and K„ = 5 g/ dm³. The rate of substrate consumption is related to growth rate by: -rs = Ys/c\g Where Ysc is the grams of substrate consumed per gram of cells produced, 1.25 for this system.
