Methanocatella gottschalkii HO
Introduction
Methanocatella gottschalkii HOT (formerly known as Methanobrevibacter gottschalkii) is a type strain isolated from the enrichment of horse faeces[1]. This methanogen, along with Methanobrevibacter ruminantium, comprises about 74% of total archaeal OTUs from rumen samples collected across geographical regions, hosts, and diets [2]. This universality and limited diversity could make it possible to mitigate methane emissions by developing strategies that target the few dominant methanogens.
