"Methanogenesis" Natural Recordings by Native Speakers
Methanogenesis is the process by which microorganisms, such as archaea and bacteria, convert carbon-rich compounds into methane (CH4) as a metabolic byproduct. This process occurs in the absence of oxygen, typically in environments with low oxygen levels, such as deep-sea sediments, terrestrial wetlands, and the digestive systems of ruminant animals. Methanogenesis is an important part of the global carbon cycle, as it regulates the levels of methane in the Earth's atmosphere and plays a key role in shaping the planet's climate.
Methanisation is a process of anaerobic digestion, where microorganisms break down organic matter, such as biomass or wastewater, in the absence of oxygen, producing biogas, which is mainly composed of methane and carbon dioxide.
