Detailed explanation-1: -Heat has been reported to damage different cell structures, including damage to cell membranes, ribosomes, DNA, RNA and enzymes. DNA is still considered the most likely lethal target molecule, but damage occurring at the same time in different molecules and/or structures may also result in heat inactivation.
Detailed explanation-2: -Heat can kill microbes by altering their membranes and denaturing proteins. The thermal death point (TDP) of a microorganism is the lowest temperature at which all microbes are killed in a 10-minute exposure.
Detailed explanation-3: -Moist heat causes destruction of micro-organisms by denaturation of macromolecules, primarily proteins. Autoclaving (pressure cooking) is a very common method for moist sterilization. It is effective in killing fungi, bacteria, spores, and viruses but does not necessarily eliminate prions.
