The production of a product P from a particular gram-negative bacteria follows the Monod growth law rg = µmaxCsCc/Ks + Cs
with µmax = 1h −1 , Ks = 0.2g/dm3 and Yc/s = 0.5 g/g.
(a) The reaction is to be carried out in a batch reactorwith the initial cell concentration ofCc0 = 0.1 g/dm3 and substrate concentration ofCs0 = 20 g/dm3 Cc = Cc0 + Yc/s (Cs0 − Cs )
Plot rg, –rs, –rc, Cs, and Cc as a function of time.
(b) The reaction is now to be carried out in a CSTR with Cs20 g/dm3 and C
(c) For the conditions in part (b), what is the dilution rate that will give the maximum product rate.
