Diverse aerobic bacteria oxidize the three most abundant reduced trace gases in the atmosphere, namely hydrogen(H₂), carbon monoxide(CO) and methane(CH₄). This review describes the taxonomic distribution, physiological role and biochemical basis of microbial oxidation of these atmospheric trace gases, as well as the ecological, environmental, medical and astrobiological importance of this process.  1, record 1, English, - microbial%20oxidation

Dans les lacs, une grande quantité de matière organique est dégradée de façon anaérobie dans les sédiments et les eaux anoxiques, produisant du CH₄. Une partie du CH₄ produit est alors émise dans l'atmosphère - par ébullition ou diffusion - mais une autre partie conséquente n'atteint jamais l'atmosphère à cause de l'oxydation microbienne dans ces écosystèmes.  1, record 1, French, - oxydation%20microbienne

Methane oxidation is a microbial metabolic process for energy generation and carbon assimilation from methane that is carried out by specific groups of bacteria, the methanotrophs. Methane(CH4) is oxidized with molecular oxygen(O2) to carbon dioxide(CO2).  2, record 3, English, - methanotrophy

Methane occurs abundantly in nature. In the presence of oxygen this gas may be metabolized by bacteria that are able to use it as carbon and energy source. Several types of bacteria involved in the oxidation of methane have been described in literature. Methane-utilizing bacteria have in common that they can only grow on methane or methanol and not on other carbon compounds.  1, record 4, English, - methane%2Dutilizing%20bacterium

In this form of transport detector for h. p. l. c. [high-performance liquid chromatography], the eluate is deposited upon a fine stainless steel wire that has been cleaned by being heated at 850°C. The volatile solvent is evaporated and the solute oxidized at 700-800°C in air to a mixture of carbon dioxide and water. The oxidation products are mixed with hydrogen and passed over a nickel catalyst at 330°C to give methane which is burnt in a flame ionization detector to give an electrical signal that can be amplified and recorded. The detector gives a linear response over a wide concentration range [...] The sensitivity has been improved and the noise level reduced by using either a ceramic(kaolin) or ceramic-metal(kaolin and copper) coating to the wire.  1, record 5, English, - wire%20transport%20detector

En cette saison l'atmosphère se refroidit par rayonnement de telle sorte que la température de la stratosphère atteint les minima terrestres les plus faibles: environ - 100 ° C. A ces températures, la vapeur d'eau stratosphérique se transforme en cristaux de glace formant des nuages qui restent en suspension dans l'atmosphère pendant tout l'hiver austral.  2, record 6, French, - vapeur%20d%27eau%20stratosph%C3%A9rique
