Context: A study conducted by researchers at the University of Washington suggests that utilizing bacteria known as methanotrophs, which consume methane, could potentially slow down the rate of global heating.


  • Methane is a potent greenhouse gas emitted from various sources including energy production, industry, agriculture, and waste management.
  • The researchers have identified a specific strain of bacteria, methylotuvimicrobium buryatense 5GB1C, that efficiently removes methane, even when present in lower concentrations.
  • Unlike many other proposed methane reduction strategies, this method doesn’t produce nitrous oxide emissions, which have a significant global warming potential.
