通过高效液相色谱电喷雾电离质谱法筛选与巴基斯坦边缘深海沉积物中甲烷渗漏相关的微生物群落的完整极性脂质（IPL）组成，检测到了新的心磷脂。一系列初步鉴定的心磷脂类似物（二聚磷脂或双磷脂酰甘油，BPG）占总古细菌IPL的0.5%至5%。这些分子与最近描述的来自极端嗜盐古细菌的具有四个植烷基链的心磷脂类似物相似。值得注意的是，来自渗漏古细菌群落的心磷脂类似物由四条类异戊二烯链组成，它们可能包含链长（20和25个碳原子）和不饱和度的差异以及羟基的存在。两个新的二醚脂质，结构相关的BPG，被描述和解释为古菌心磷脂类似物的降解产物。由于渗漏沉积物中的古菌群落主要由厌氧甲烷氧化菌，我们的观察结果具有影响的特征古菌膜的结构组成部分，其中BPG被假定为有助于调制细胞的渗透性能。BPG是否促进种间相互作用的互养甲烷营养财团仍有待测试。
Novel cardiolipins from Archaea were detected by screening the intact polar lipid (IPL) composition of microbial communities associated with methane seepage in deep‐sea sediments from the Pakistan margin by high‐performance liquid chromatography electrospray ionization mass spectrometry. A series of tentatively identified cardiolipin analogues (dimeric phospholipids or bisphosphatidylglycerol, BPG) represented 0.5% to 5% of total archaeal IPLs. These molecules are similar to the recently described cardiolipin analogues with four phytanyl chains from extreme halophilic archaea. It is worth noting that cardiolipin analogues from the seep archaeal communities are composed of four isoprenoidal chains, which may contain differences in chain length (20 and 25 carbon atoms) and degrees of unsaturation and the presence of a hydroxyl group. Two novel diether lipids, structurally related to the BPGs, are described and interpreted as degradation products of archaeal cardiolipin analogues. Since archaeal communities in seep sediments are dominated by anaerobic methanotrophs, our observations have implications for characterizing structural components of archaeal membranes, in which BPGs are presumed to contribute to modulation of cell permeability properties. Whether BPGs facilitate interspecies interaction in syntrophic methanotrophic consortia remains to be tested.
