Answer to Question #130818 in Mechanical Engineering for Kamanam Sai Kumar

Question #130818
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/ L. The protozoa are cultured at steady state in a chemostat using a feed stream containing 10 g 1 of nonviable bacteria. What is the maximum dilution rate for operation of the chemostat?
Expert's answer

Doubling time is given as ,

Td= 6.5 , We know that

Dilution rate= , here F=Volumetric flow rate, V= Volume

and under case of limiting substrate

And in case of limiting substrate, here, D= Dilution rate


D= 0.1066 , This is dilution rate
