Typically, the heat is below the boiling point of water (100 °C or 212 °F). These discoveries formed the "germ" of Pasteur's germ theory of fermentation. By the 1890s, wider acceptance of germ theory resulted in the emergence of the science of bacteriology, and new research revealed that antiseptics were not the only way to control infection. In his first job as a surgical dresser he accompanied the surgeon on his rounds, cleaning and re-dressing surgical wounds, seeing first-hand the various levels of decaying flesh, pus and other bodily secretions resulting from infections.
