asexual reproductive process in which one cell divides into two separate genetically identical cells
autotrophic process where organisms obtain energy from the breakdown of inorganic compounds containing sulfur and nitrogen
form of sexual reproduction in some bacteria where one bacterium transfers all of part of its genetic material to another through a bridgelike structure calles a pilus
Structure formed by bacteria during unfavorable conditions that contains DNA and a small amount of cytoplasm encased by a protective outer covering: germinates during favorable conditions.
nitrogen fixation
metabolic process in which bacteria use enzymes to convert atmospheric nitrogen (N2) into ammonia (NH3).
obligate aerobe
bacteria that require oxygen for cellular respiration
obligate anaerobe
