WebOne of the most-prominent differences between bacteria is their requirement for, and response to, atmospheric oxygen (O 2 ). Whereas essentially all eukaryotic organisms require oxygen to thrive, many species of bacteria can grow under anaerobic conditions. Bacteria that require oxygen to grow are called obligate aerobic bacteria. WebAn aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does …

WebStrict anaerobes do not grow in 10% CO 2 in air; microaerophilic bacteria can grow in 10% CO 2 in air or under aerobic or anaerobic conditions, and facultative organisms can grow in the presence or absence of air. The physiologic basis for oxygen sensitivity is … WebThe classical and strict distinction between aerobic (Bacillus, Thermoactinomyces, Sporolactobacillus, and Sporosarcina) and anaerobic (Clostridium) spore formers no longer holds; it is now known that, given the right environment, Bacillus subtilis and other Bacillus species can grow quite well anaerobically. WebAerobic and anaerobic bacteria can be identified by growing them in test tubes of thioglycollate broth: 1: Obligate aerobes need oxygen because they cannot ferment or respire anaerobically. They gather at the top of the tube where the oxygen concentration is highest. 2: Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of … the village fort dodge iowa
