Abstract

The methanogenic bacterium Methanobacterium thermoautotrophicum (A.T.C.C. 29183) was shown to contain two new aminophospholipids. These are 2-aminoethyl phosphate ester of diphytanylglycerol diether and a sugar containing bisdiphytanyldiglycerol tetraether. The two aminophospholipids were stable to acid methanolysis except for the sugar on the bisdiphytanyldiglycerol tetraether. Strong acid (6 M-HCl) hydrolysed the alkyl ether and aminophosphate ester bonds. The structure of the phosphate linkage was demonstrated by 31P n.m.r., and the 2-ethanolamine structure was elucidated by 1H- and 13C-n.m.r. spectroscopy and by fast-atom-bombardment m.s.
