Can archaea survive without oxygen
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. However, some species, such as the Chytridiomycota that reside in the rume… WebOct 23, 2024 · 3. Facultative bacteria gather mostly at the top since aerobic respiration is most efficient, but since they can survive with a lack of oxygen, they can be found throughout the culture. 4. Microaerophiles gather at the upper part of the test tube but not at the top. They require oxygen but are poisoned by high concentrations of oxygen. 5.
