Chemostat culture with protozoa Tetrahymena thermophila protozoa have a minimum doubling time of 6.5 hours when grown using bacteria as the limiting substrate. The yield of protozoal biomass is 0.33 g per g of bacteria and the substrate constant is 12 mg l1 . The protozoa are cultured at steady state in a chemostat using a feed stream containing 10 g l1 of nonviable bacteria. (a) What is the maximum dilution rate for operation of the chemostat
