E. coli is grown in a chemostat with a working volume of 1.0 litre. A medium containing 4 g litre¹ of glucose as growth limiting substrate is fed to the fermenter at a constant flow rate of 0.5 litre h*¹. The glucose concentration in the outlet stream is 0.2 g litre-1. The cell yield (Yxs) is 0.42 g g¹¹. Determine the cell concentration in the output stream and the specific growth rate. [Ans: x= 1.6 g L¹; μ = 0.5 h¹]
