Liquid chromatography-electrospray tandem mass spectrometry (LC/ESI-MS/MS) was used to analyze phospholipids from three species of the anaerobic beer-spoilage bacterial genus Pectinatus. Analysis of total lipids by HILIC (Hydrophilic Interaction Liquid Chromatography) column succeeded in separating diacyl- and plasmalogen phospholipids. Plasmalogens were then analyzed by means of the ESI-MS/MS and more than 220 molecular species of four classes of plasmalogens (PlsCho (choline plasmalogen), PlsEtn (ethanolamine plasmalogen), PlsGro (glycerol plasmalogen), and PlsSer (serine plasmalogen)) were identified. Major molecular species were c-p19:0/15:0 PlsEtn and PlsSer, which accounted for more than 4% of the total lipids.
采用液相色谱 - 电喷雾串联质谱法(LC/ESI-MS/MS)分析了厌氧啤酒腐败细菌果胶杆菌属三种菌的磷脂。通过亲水相互作用液相色谱(HILIC)柱对总脂质进行分析,成功分离出二酰基磷脂和缩醛磷脂。然后借助电喷雾串联质谱法对缩醛磷脂进行分析,鉴定出四类缩醛磷脂(胆碱缩醛磷脂(PlsCho)、乙醇胺缩醛磷脂(PlsEtn)、甘油缩醛磷脂(PlsGro)和丝氨酸缩醛磷脂(PlsSer))的220多种分子种类。主要分子种类为c-p19:0/15:0 PlsEtn和PlsSer,占总脂质的4%以上。
