Methanococcus maripaludis e um arquea metanogenico mesofilico e hidrogenotrofico da familia Methanococcaceae, isolado de sedimentos de pântano salgado. Tornou-se um importante organismo modelo para estudar a metanogenese, o metabolismo arqueal e a regulacao genica, devido as ferramentas geneticas bem desenvolvidas disponiveis para esta especie. Produz metano reduzindo dioxido de carbono com hidrogenio em condicoes estritamente anaerobias.
