    en.wikipedia.org/wiki/Oxygen_toxicity

    Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O 2) at increased partial pressures.Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes.

    en.wikipedia.org/wiki/Anaerobic_organism

    A number of techniques are employed by microbiologists when culturing anaerobic organisms, for example, handling the bacteria in a glovebox filled with nitrogen or the use of other specially sealed containers, or techniques such as injection of the bacteria into a dicot plant, which is an environment with limited oxygen.

    en.wikipedia.org/wiki/Aspergillus_wentii

    In its natural environment, Aspergillus wentii is aerobic, able to grow, replicate, and produce metabolites optimally in an oxygen-rich environment. [ 9 ] [ 4 ] Under light exposure, Aspergillus wentii cultures have been observed to produce white aerial mycelium (at times expressing a pink hue) in large masses that can often expand to fit ...

    Excessive exposure to oxygen can lead to oxygen toxicity, also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning.There are two main ways in which oxygen toxicity can occur: exposure to significantly elevated partial pressures of oxygen for a short period of time (acute oxygen toxicity), or exposure to more modest elevations in oxygen partial pressures but for a ...

    Fertiliser was added to some of the beaches in Prince William Sound in an attempt to promote the growth of these naturally occurring bacteria after the 1989 Exxon Valdez oil spill. These efforts were effective on beaches that were not too thickly covered in oil. Bacteria are also used for the bioremediation of industrial toxic wastes. [239]

    en.wikipedia.org/wiki/Breathing_gas

    A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
