Why are Endospores Used to Measure the Effectiveness of Autoclave

Question

Why are endospores used to measure the effectiveness of autoclave sterilization?
A) Endospores are easy to store in the lab until needed.
B) Endospores are very simple structures and easy to detect.
C) Endospores are very hard to kill.
D) Endospores are composed of all the molecules found in living cells.
E) Endospores of different bacteria are destroyed at different temperatures and can be used to calibrate autoclave temperatures.

Accepted Answer

Endospores are very hard to kill, making them ideal indicators of the effectiveness of sterilization techniques like autoclaving. Autoclaves use high pressure and temperature to kill microorganisms, and if they can kill endospores, they are likely to be effective at killing other types of microorganisms as well.
