👉 Methanobrevibacter is a type of bacteria that primarily lives in aquatic environments, specifically in bodies of water where there are high levels of dissolved oxygen and nutrients. It is an important component of the methanotrophy process, which is a metabolic pathway that converts organic waste into energy through the breakdown of methane (CH4) into butane (C3H8). This process is essential for maintaining the health and productivity of aquatic ecosystems.
