First of all, What is the difference between disinfection, sanitation and sterilization?
Disinfection uses antimicrobial agents on non-living objects or surfaces to destroy or inactivate microorganisms.
Disinfectants may not kill all bacteria, viruses, fungi and spores.

reduce the number of disease-causing organisms to non-threatening
Sanitizing does not affect some spores and viruses.
your hands with soap and warm water like a surgeon does is more
effective than sanitizing your hands. Sanitizers attempt to kill the
organisms. Washing simply removes them, and it removes them so well if
done right that it's far more effective than hand sanitizer.
Sterilization is the probability
that all bacteria, spores, fungi and viruses are killed or inactivatedhttps://en.wikipedia.org/wiki/Sterility_assurance_level
Disinfection 101 (a PDF)Pasteurization
pasteurization is different from both sanitation and sterilization, but is more similar to sanitation. https://en.wikipedia.org/wiki/Pasteurization
For mycology purposes we pasteurize substrates, which doesn't have much in common with the way dairy and alcoholic beverages are pasteurized.
Substrates that are at field capacity are heated. They are held at 140-160F measured core temperature for about one hour. Then they are allowed to cool down naturally. the substrate should not be left in the heat as to cool down slowly, and should not be placed in something cooler than ambient temperatures as to speed things up.
This can be accomplished many different waysCorrect Pressure cooker use
