Answer 2

Sterilization

B. Δoverall = Δheating + Δholding+ Δcooling

Sterilization is a process by which an article, surface or medium is made free of all microorganisms either in vegetative or spore form. We need sterilization to remove or destroy the infection causing microorganism from materials or from surfaces.

Del factor is defined as an estimate of relative reduction in the number of living cells with respect to their initial number.
