Which of the following statements are true about bioreactors?
P. Continuous bioreactors provide less degree of control and uniform product quality than batch bioreactors.
Q. Batch bioreactors are ideally suited for reaction with substrate inhibition.
R. Choice of a bioreactor is dictated by kinetic considerations.
S. Fed batch bioreactors are also called semi-batch bioreactors.
Which of the following statements is always correct about an ideal chemostat?
P. Substrate concentration inside the chemostat is equal to that in the exit stream.
Q. Optimal dilution rate is lower than critical dilution rate.
R. Biomass concentration increases with increase in dilution rate.
S. Cell recirculation facilitates operation beyond critical dilution rate.
Wash out (as defined by D = μmax) of a continuous stirred tank fermenter is characterized by (X = biomass, S = substrate concentration in bioreactor, S0 = substrate concentration in feed, P = product concentration in bioreactor).
Determine the correctness or otherwise of the following Assertion (A) and Reason (R). Assertion: Immobilization of plant cells can enhance secondary metabolite production during bioreactor cultivation. Reason: Immobilization protects the plant cells from shear forces in the bioreactor.
