Lactobacillus phospholipid molecular species were analyzed by mass spectrometry. Prominent anions were consistent with presence of the phosphatidylglycerols PG(37:2), PG(36:2), PG(35:1), PG(34:1), and PG(33:1). Diglycosyldiacylglycerol molecular species were also observed, although nitrogen-containing phospholipids were absent. An anion of m/z 759 was derived from an apparently novel type of lipid.
通过质谱分析了乳酸杆菌的磷脂分子种类。主要阴离子与磷脂酰甘油PG(37:2)、PG(36:2)、PG(35:1)、PG(34:1)和PG(33:1)的存在一致。还观察到了二糖基二酰基甘油分子种类,尽管不含含氮磷脂。质荷比为759的阴离子源自一种明显新型的脂质。
