Haloarchaeen
WebMethanogenese oder Biomethanisierung ist die Bildung von Methan durch Mikroben, die als Methanogene bekannt sind. Organismen, die Methan produzieren können, wurden nur aus der Domäne Archaea identifiziert, einer Gruppe, die sich phylogenetisch sowohl von Eukaryoten als auch von Bakterien unterscheidet, obwohl viele in enger Assoziation mit ... http://www.cazy.org/a16637.html
