The production of a product P from a particular gram-negative bacteria follows the Monod growth law max CsCc rg = Ks+Cs = with μmax = 1 h-¹, Ks = 0.25 g/dm³, and Yc/s 0.5 g/g. (a) The reaction is to be carried out in a batch reactor with the initial cell concentration of Cco = 0.1 g/dm³ and substrate concentration of C5o = 20 g/dm³. Cc Cco+Yc/s(Cs0 - Cs) Plot r-rs-re Cs, and C as a function of time. (b) The reaction is now to be carried out in a CSTR with Cso = 20 g/dm³ and Co = 0. What is the dilution rate at which wash-out occurs? (c) For the conditions in part (b), what is the dilution rate that will give the maximum product rate (g/h) if Y = 0.15 g/g? What are the concentrations C, C₁, C₂, and -r, at this value of D?
