D-Alanylcardiolipin, a major component of the unique lipid pattern of Vagococcus fluvialis.

ABSTRACT: Motile group N streptococci, classified as Vagococcus fluvialis, have been isolated from cows' udders, human and animal feces, river water, and seawater. They possess an unusual membrane lipid and fatty acid pattern. We isolated and characterized 13 polar lipids, 8 of them also found in other gram-positive bacteria: mono- and dihexosyldiacylglycerol, an acylated and a glycerophosphate-substituted derivative of the latter, cardiolipin, phosphatidylglycerol, D-alanylphosphatidylglycerol, and L-lysylphosphatidylglycerol. Besides them, we characterized two rare compounds, bis(acylglycero)phosphate and alpha-D-glucopyranosylcardiolipin, and two compounds so far not detected in nature, D-alanylbis(acylglycero)phosphate and D-alanylcardiolipin. The concomitant occurrence of four aminoacyl phospho
