What is the effect of freezing on bacteria?
Bacteria like Archaebacteria can survive in extreme temperatures but eubacteria cannot. Since Eubacteria die from the harsh temperature and Archaebacteria cannot reproduce your immune system kills all of the Archaebacteria. That is why freezing in a technical sense stops bacteria from reproducing.
Why do refrigeration and freezing preserve foods?
