A microbial fermentation to produce ethanol is performed in a 50L CSTR or chemostat. Glucose plus minerals and trace elements are fed to the chemostat at 5 L/h with a glucose concentration 30 g/L (CSo). Determine the steady-state concentration of glucose, CS, and cells, CC, with a cell maintenance requirement, m, of 0.05 g-substrate/g-cell/h. The microorganism has the following kinetic characteristics max = 0.5 h-1, KS = 5 g/L, YC/S=0.5 g-cell/g-substrate
