mikroaerofiilisiä
Mikroaerofiilisiä refers to microorganisms that require a low concentration of oxygen for growth. This oxygen level is typically less than that found in the Earth's atmosphere, which is about 21%. Instead, they thrive in environments where oxygen levels are between 2% and 10%. These organisms cannot survive in the complete absence of oxygen, distinguishing them from obligate anaerobes, nor can they tolerate the higher oxygen concentrations found in atmospheric air, which can be toxic to them.
The requirement for low oxygen often stems from their metabolic processes. Some microaerophiles may possess enzymes
Examples of microaerophilic bacteria include Helicobacter pylori, the bacterium associated with stomach ulcers, and Campylobacter jejuni,
