- Methylotuvimicrobium buryatense 5GB1C is an extant gammaproteobacterial methanotroph that can grow at low methane concentrations in the range from 200 ppm to 1,000 ppm.
| Methane is a potent greenhouse gas and has a global warming potential over 85 times greater than carbon dioxide on a 20-year timescale. Atmospheric methane accounts for about 30% of total global warming. |
- It exhibits greater methane consumption rates at both low and high methane compared to other methanotroph strains.
- These features make this strain a promising candidate for methane removal technology at emission sites with enriched methane in air like- landfills, paddy fields, and oil and gas wells.
ABOUT METHANOTROPHS
- Methanotrophs are bacteria for which methane is their carbon and energy source.
- Such bacteria naturally convert methane to CO2 and biomass, a value-added product and a cobenefit of methane removal.
- Typically, methanotrophs grow best at around 5,000 to 10,000 ppm methane, but methane in the atmosphere is 1.9 ppm.
