mikroaerobic

Mikroaerobic refers to an environment that contains a lower concentration of oxygen than is normally found in the atmosphere. Organisms that thrive in such conditions are called microaerophiles. These organisms utilize oxygen for respiration but are harmed by the higher concentrations present in the air. The specific oxygen level required by microaerophiles can vary, but it is generally between 2% and 10%.

Microaerophilic environments can be found in various natural settings. Examples include the sediment of lakes and oceans, the digestive tracts of animals, and within the tissues of plants. In medical contexts, microaerophiles are significant as some can cause infections. For instance, Helicobacter pylori, a bacterium that causes stomach ulcers, is a well-known microaerophile.

The growth and survival of microaerophilic organisms depend on carefully controlled atmospheric conditions. In laboratory settings, specialized incubators are used to maintain the required low oxygen levels. These incubators can be flushed with specific gas mixtures or utilize chemical oxygen absorbers. Understanding the oxygen requirements of these microorganisms is crucial for their cultivation, identification, and the study of their role in various biological and pathological processes. The term "mikroaerobic" is derived from Greek words meaning "small" or "little" and "air," reflecting the organism's limited need for oxygen.
