- e Serves as a source of protection when environmental conditions are not favorable for survival or growth. Such as - heat, drying, poor nutrient supply, chemical. Only two genera of bacteria are capable of forming spores: bacillus, clostridium. Distinction between sporulating and vegetative bacteria: - under any of the adverse conditions mentioned earlier, the cell will be stimulated to form an endospore. A process called sporulation. When the conditions for growth improve, the endospore will then convert into a living, growing, vegetative cell. Germination. Importance to the embalmer - the genera that are able to form spores include the species that cause tetnus, anthrax, botulism, gas gangrene, and tissue gas. Therefore the normal procedures of disinfection and sterilization are often not sufficient to control the growth of these organisms.
