Abstract

An anaerobic, mesophilic, syntrophic, archaeon strain MK-D1 T , was isolated as a pure co-culture with Methanogenium sp. strain MK-MG from deep-sea methane seep sediment. This organism is, to our knowledge, the first cultured representative of ‘Asgard’ archaea, an archaeal group closely related to e...
