Methanotrophs were isolated from a hydrogen sulfide (H2S)-rich anaerobic digester.
- class="label">•
One isolate, Methylocaldum gracile SAD2, can grow at 1000 ppm H2S in the headspace.
- class="label">•
Strain SAD2 showed greater H2S tolerance than two commonly studied methanotrophs.
- class="label">•
Strain SAD2 produced 275 mg/L methanol in the presence of 500 ppm H2S.
- class="label">•
This is the first reported methanotroph that converts H2S-rich biogas to methanol.
