Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of
life and other
biological agents (such as
fungi,
bacteria,
viruses,
spore forms,
prions,
unicellular eukaryoticorganisms such as
Plasmodium, etc.) present in a specified region, such as a surface, a volume of fluid, medication, or in a compound such as biological
culture media.
[1][2] Sterilization can be achieved through various means, including:
heat,
chemicals,
irradiation,
high pressure, and
filtration. Sterilization is distinct from
disinfection, sanitization, and
pasteurization, in that sterilization kills, deactivates, or eliminates all forms of life and other biological agents which are present.
I am sorry English is not my first languange so i cannot always put everything as clearly as i would like to but when it come to sterilisation
there is clear distinction between bacteris and it spors and you are right that sterilisation process can be assest by destroying spores but bacterias not spores die before spore forms are shall i say destroyed.
And while i am at it i can see now who recommeds 180min not 120 :/
