Abstract
Glyceryl ether phospholipids were found to exist in various strictly anaerobic bacteria and propionibacteria. The strains included Selenomonas ruminantium, Veillonella gazogenes, Propionibacterium freudenreichii, Propionibacterium shermanii, Clostridium saccharoperbutylacetonicum, Clostridium acetobutylicum, Clostridium perfrigens, and Clostridium kaneboi. Selenomonas ruminantium contained the largest amount of glyceryl ether phospholipids among the tested bacteria. The molar percentage composition of glyceryl ethers in total phospholipids from Selenomonas ruminantium was approximately 3. Glyceryl ether phospholipid was not detected in aerobic and facultative anaerobic bacteria even when they were cultured under strictly anaerobic conditions.
