ResumoThe membrane lipid of a new deep-sea hydrothermal vent methanogen, Methanococcus jannaschii, has been structurally characterized. The hydrolyzed polar lipid of this archaebacterium is primarily (95 percent) a macrocyclic glycerol diether, which has not been described previously. The structure was elucidated by a combination of chemical and spectroscopic techniques. An initial survey of selected methanogens failed to indicate the presence of this membrane lipid in any microorganism other than Methanococcus jannaschii.
