Methylomirabilaceae

Methylomirabilaceae is a family of bacteria, represented by type genus Ca. Methylomirabilis. Represented most famously by the novel methane-oxidizing bacterium Ca. Methylomirabilis oxyfera, which appears to split oxygen from nitrates, it contains several other genera not yet described.
SILVA 138.1 lists 6 uncultured genera currently within the family:

Candidatus Methylomirabilis
MIZ14
MIZ17
SH765B-TzT-35
wb1-A12
Z114MB74

These genera are consistently described in methane-rich environments, but only species within Candidatus Methylomirabilis are confidently described as methane-oxidizers.
