The spore loses its characteristic constituents, and warmth resistance decreases drastically. In the last stage h2o is taken up, and metabolism (synthesis of ATP, proteins and genetic product) resumes. Warmth activation is a vital factor in the occurrence of a shoulder within the survival curve of bacterial spores on heating.
