Question

_______________ are the reactors containing a settled bed of immobilised enzyme particles.

(a) Continuous Stirred tank batch reactors

(b) Packed bed reactor

(c) Stirred tank batch reactors

(d) Fluidized bed reactors

This question was posed to me by my college director while I was bunking the class.

My enquiry is from Immobilized Enzymes in division Immobilized Enzymes and their Uses of Enzyme Technology

Answer 1

Right choice is (b) Packed bed reactor

Explanation: Packed bed reactor is one in which the reactor contains a settled bed of immobilised enzyme particles. This is also called as plug-flow reactor. Stirred tank batch reactors are those in which all of the product is removed after fixed time. Whereas continuous version of this is referred to as continuous Stirred tank batch reactors. The reactor where in the flow of gas and/or substrate keeps the immobilised enzyme particles in a fluidized state is referred to as fluidized bed reactor.
