A stream of growth medium containing 60% glucose and 40% growth factor A flowing at 500 kg per hour was divided into two feed streams for different cell cultures. One fourth of the growth medium was sent to fermenter 1 and the rest was sent to fermenter 2. What is the flow rates of glucose and growth factor A in the feed streams for the two fermenters

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
