Introduction
Methanocatella gottschalkii HOT (formerly known as Methanobrevibacter gottschalkii) is a type strain isolated from the enrichment of horse faeces[1]. M. gottschalkii, along with Methanobrevibacter ruminantium, comprises about 74% of total archaeal OTUs from rumen samples collected across geographical regions, hosts, and diets[2]. This universality makes them methanogens of utmost interest to the Global Methane Hub, as it could enable strategies to mitigate methane emissions by targeting only these dominant methanogens.

Methylome
| #motif | methylCounts | totalCounts | %motifsMethyl |
| C(6mA)YNNNNNRTTG | 1495 | 1558 | 95.96 |
| CA(6mA)YNNNNNRTG | 1522 | 1558 | 97.69 |
The methylome was analyzed using MIJAMP[3]. 4mC and 5mC methylation motifs were not present in this isolate.

Culturing Conditions
M. gottschalkii HO is cultivated in GMH-VT2 medium at 37°C and 50 rpm with a 30 psig gas mixture of H2:CO2 (80:20, v/v) as an energy substrate for 24-48 h. This methanogen can also be cultivated on GMH-VT2 plates using 1.5% gelrite or 2% agar as a gelling agent with a 12 to 30 psig H2:CO2 (80:20, v/v) gas mixture as an energy substrate for 2-5 days. The viability of M. gottschalkii on agar plates is 10-30 times higher than that of those grown on gelrite plates.
