Problem \#2 (25 points) Given the following information for an E. coli culture producing biomass (max=1.0hr1):S0=10g/L,S=0.1g/L,Xm=2g cells /L,X0=0.25g cells /L kd=0.01hr1;Ks=0.01g/L,tlag=0.3hr(D=0.2hr1, sterile feed for the chemostat ). (A) Calculate the post-batch processing time needed to give a 3:1 ratio of rates of biomass production of continuous versus batch bioreactors (rc,opt/rb)
