WebMar 5, 2024 · The growth of bacteria with varying oxygen requirements in thioglycolate tubes is illustrated in Figure 9.2. 2. In tube A, all the growth is seen at the top of the tube. The bacteria are obligate (strict) aerobes … An anaerobic organism or anaerobe is any organism that does not require molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment. Anaerobes may be unicellular (e.g. protozoans, bacteria ) or multicellular. Most fungi are obligate aerobes, requiring oxygen to survive.
