Glossary | SPORES

Certain of the rod forms of bacteria produce spores. These are not reproductive bodies, as in the case of molds and yeasts, but are the resting stage of the organism. In the spore state, bacteria can survive extremes of cold, heat, drying, and other unfavorable conditions for long periods of time; and when the environment is again favorable, the spores germinate, and the organisms start another cycle of growth. Growing cells are called “vegetative” cells. Spore-forming bacteria which can grow in the presence or absence of air (facultative anaerobes) are classified in the genus Bacillus, while those which grow only in the absence of air are classified in the genus
