Methanobacterium
Sign in to saveMethanobacterium (from Latin methanum, meaning "methane", and bactērium) is a genus of the Methanobacteria class in the Archaea domain, which produce methane as a metabolic byproduct. Despite the name, this genus belongs not to the bacterial domain but the archaeal domain (for instance, they lack peptidoglycan in their cell walls). Methanobacterium are nonmotile and live without oxygen, which is toxic to them, and they only inhabit anoxic environments.

Methanobacterium ist eine Gattung von prokaryotischen Mikroorganismen,[1] also eine Gattung von Lebewesen, deren Zellen keinen echten Zellkern aufweisen. Anders als der Namensteil „bacterium“[A 1] annehmen lässt, gehört Methanobacterium nicht zu den Bacteria, sondern in die Domäne Archaea.[A 2] Es ist stäbchenförmig, anaerob, bildet Methan und wurde 1936 beschrieben.[2] Inhaltsverzeichnis 1 Eigenschaften 2 Systematik 2.1 Überblick 2.2 Namen 2.2.1 Namensherkunft 2.2.2 Mehrdeutige Benennungen 2.2.2.1 Mehrdeutige Übersetzungen 2.2.2.2 Mehrdeutige Zuweisung von Kulturstämmen 2.2.2.3 Mehrdeutige Klassifizierung 2.3 Arten der Gattung 2.3.1 Aktuelle Arten 2.3.2 Frühere Arten 2.4 Phylogenetik 3 Vorkommen und Bedeutung 4 Datenbanken 5 Anmerkungen 6 Einzelnachweise Eigenschaften Die Zellen sind gerade, gekrümmte oder gebogene Stäbchen, die lang bis fadenförmig sind und ca. 0,5 bis 1,0 Mikrometer (µm) Durchmesser aufweisen.[3] Endosporen werden nicht gebildet.[3] Methanobacterium ist unbeweglich und Fimbrien können vorhanden sein.[3] Die Zellwände unterscheiden sich chemisch vom Peptidoglycan und erscheinen normalerweise als Gram-positiv, sowohl bei der Gramfärbung als auch bei elektronenmikr

Methanobacterium (from Latin methanum, meaning "methane", and bactērium) is a genus of the Methanobacteria class in the Archaea domain, which produce methane as a metabolic byproduct. Despite the name, this genus belongs not to the bacterial domain but the archaeal domain (for instance, they lack peptidoglycan in their cell walls). Methanobacterium are nonmotile and live without oxygen, which is toxic to them, and they only inhabit anoxic environments.
A shared trait by all methanogens is their ability to recycle products. They can use the products of metabolic activities occurring during methanogenesis as substrates for the formation of methane. Methanobacterium species typically thrive in environments with optimal growth temperatures ranging from 28 to 40 °C, and in versatile ecological ranges. They are a part of the scientific world that is still relatively unknown, but methanogens are thought to be some of earth's earliest life forms. They do not create endospores when nutrients are limited. They are ubiquitous in some hot, low-oxygen environments, such as anaerobic digesters, wastewater, and hot springs.
