Question 18
XL-SNAT2 marksNeeds review
A continuous cell culture being carried out in a stirred tank reactor is described in terms of its cell mass concentration X and substrate concentration S. The concentration of the substrate in the sterile feed stream is S_F = 10 g/L and yield coefficient Y_{x/s} = 0.5. The flow rates of the feed stream and the exit stream are equal (F=5 mL/min) and constant. If the specific growth rate (h⁻¹) μ = \frac{0.3\ S}{(1+S)}, the steady state concentration of S is ____ g/L (up to 1 decimal point).
