Biomass is being produced in a continuous stirred tank bioreactor of 750 L capacity. The sterile feed containing 8 g L-1 glucose as substrate was fed at a flow rate of 150 L h-1. The microbial system follows Monod's model with μm = 0.4 h-1, KS = 1.5 g L-1 and \[{Y_{\frac{X}{S}}}\] = 0.5 g cell mass-g substrate-1. Determine the cell productivity (g L-1 h-1) at steady state.
A. 0.85
B. 0.65
C. 0.45
D. 0.25
