Introduction
Methanocatella millerae SM9 (formerly Methanobrevibacter millerae) was isolated from the rumen of a sheep fed a fresh forage diet[1]. Although initially identified as Methanobrevibacter sp. or M. smithii, SM9 shares 99% 16S rRNA gene sequence identity with the M. millerae type strain ZA-10ᵀ (DSM 16643), supporting its assignment to this species[2]. Its robust growth and high plating efficiency make SM9 a strain of particular interest to the Global Methane Hub.

Culturing Conditions
M. millerae SM9 is cultivated in MMSM medium at 37°C and 50 rpm with a 207 kPa of H2/CO2 (80:20, v/v) as an energy substrate for 2-4 days. This methanogen can also be cultivated on MMSM plates using 1.5% agar as a gelling agent with the same H2/CO2 as an energy substrate for 3-7 days.
