E. coli was continuously cultured in a continuous stirred tank fermenter with a working volume of 1.0 I by chemostat. A medium containing 4.0 g1^-1 of glucose as a carbon source was fed to the fermenter at a constant flow rate of 0.5 I h^-1, and the glucose concentration in the output stream was 0.20 g1^-1, The cell yield with respect to glucose YxS was 0.42 g dry cells per gram glucose. Determine the cell concentration in the output stream
