Question

The Del Factor decreases as the initial number of organisms _____________

(a) Decreases

(b) Increases

(c) Remains constant

(d) Becomes zero

I have been asked this question at a job interview.

I want to ask this question from Batch Sterilization topic in section Sterilization of Fermentation Technology

Answer 1

The correct option is (a) Decreases

Easiest explanation: The Del factor decreases as the initial number of viable organisms decreases. This happens because the Del factor is directly proportional to the initial number of viable organisms and is inversely proportional to the viable organisms after the sterilization treatment. That is why it decreases.
