Methanoculleus bourgensis
BA1, a hydrogenotrophic methanogen
,
was isolated from a laboratory-scale biogas reactor operating under an elevated ammonium concentration. Here, the complete genome sequence of
M. bourgensis
BA1 is reported. The availability of the BA1 genome sequence enables detailed comparative analyses involving other
Methanoculleus
spp. representing important members of microbial biogas communities.
Here, we report the complete genome sequence (2.92 Mb) of
Methanosphaerula palustris
E1-9C
T
, a methanogen isolated from a minerotrophic fen. This is the first genome report of the
Methanosphaerula
genus, within the
Methanoregulaceae
family, in the
Methanomicrobiales
order. E1-9C
T
relatives are found in a wide range of ecological and geographical settings.
