Summary Introduction
To tell:
Why Bacillus endospores are used as sterility indicators.
Introduction:
Sterilization is a term that implies and ensures the complete eradication of the microbe. Sterilization by heat is one of the key factors in eradicating the microbes. The heat has the capability to denature the microbe’s proteins, alter its cell wall, and cause irreversible damage to its
