The Discovery of Methane-Eating Microbes
Research has revealed the existence of unique microbes that can consume methane without oxygen, a process crucial for maintaining planetary health. These microorganisms are found in extreme environments, such as deep-sea sediment, where they thrive by splitting sulfate molecules to extract the oxygen needed for their metabolic processes. The groundbreaking discovery of anaerobic oxidation of methane has highlighted their essential role in regulating methane levels and supporting life on Earth. By understanding these microbes, scientists have gained insights into their symbiotic relationships and the environmental conditions necessary for their survival.
