Disappearance of plasmalogen-containing phospholipids in Megasphaera elsdenii.

Abstract

The plasmalogen content of phospholipids isolated from Megasphaera elsdenii ATCC 17752 decreased markedly in cultures passed serially at intervals of 3 to 6 weeks. From the wild-type ratio of vinyl ether to lipid phosphorus of 0.8, clones were isolated with ratios less than 0.05. Clonal analysis, as well as the reproducibility of the phenomenon and the long time course, suggest that the loss of plasmalogens is an adaptive process. Although small variations in cell morphology and ratios of end products of fermentation were detected, plasmalogen-rich and -deficient cells were virtually indistinguishable with respect to growth rates, range of fermentable carbohydrates, activities of selected enzymes, and electrophoretic patterns in both membrane and soluble proteins. Large decreases in saturated fatty acid production accompanied the decline of plasmalogens.
