The spore loses its attribute constituents, and warmth resistance decreases radically. In the final phase water is taken up, and metabolism (synthesis of ATP, proteins and genetic material) resumes. Heat activation is a crucial factor in the event of the shoulder in the survival curve of bacterial spores upon heating.

Decreasing the water content material has historically been a handy technique to shield foods from microbial spoilage. Illustrations in which the readily available humidity is diminished are dried fruits, syrups, and pickled meats and veggies. Small h2o action will even prevent microbial growth inside pharmaceutical preparations, see also Sect.
