Practice question
Question
The maximum cell concentration (g l^-1) expected in a bioreactor with initial cell concentration of 1.75 g l^-1 and an initial glucose concentration of 125 g l^-1 is (Yx/s = 0.6 g cell/g substrate
Explanation
Xmax =X0+ Yx/s×S0 =1.75+0.6×125=76.75 g/L. Assumes substrate fully consumed for growth, no maintenance or product formation, representing theoretical maximum biomass achievable from given glucose under yield coefficient, useful for reactor design.
