The lipids of Thermus aquaticus YT1, Thermus thermophilus HB8, Thermus sp. strains H and J (from Icelandic hot springs), and Thermus sp. strain NH (from domestic hot water) have been investigated. Each strain contained two major components, a glycolipid and a glycophospholipid, which have been isolated and analyzed. All of the strains contained as the principal component (41 to 57% of total lipid) a diacyldiglycosyl-(N-acyl)glycosaminylglucosylglycerol, but the five glycolipids differed in carbohydrate composition. The glycophospholipid appeared to be identical in each strain and contained an N-acylglucosamine residue. The principal fatty acids were C15 and C17 branched-chain compounds. This unique polar lipid composition should be of value in the classification of other thermophiles in the genus Thermus. The exceptionally high carbohydrate content of the lipids of these extreme thermophiles may be of significance in relation to the molecular basis of thermophily.
对嗜热水栖菌YT1、嗜热栖热菌HB8、嗜热栖热菌菌株H和J（来自冰岛温泉）以及嗜热栖热菌菌株NH（来自家用热水）的脂质进行了研究。每个菌株都含有两种主要成分，一种糖脂和一种糖磷脂，它们已被分离和分析。所有菌株都含有作为主要成分（占总脂质的41%至57%）的二酰基二糖基 -（N - 酰基）糖胺基葡糖基甘油，但这五种糖脂在碳水化合物组成上有所不同。糖磷脂在每个菌株中似乎是相同的，并且含有一个N - 酰基葡糖胺残基。主要脂肪酸是C15和C17支链化合物。这种独特的极性脂质组成在嗜热栖热菌属其他嗜热菌的分类中应该具有价值。这些极端嗜热菌脂质中异常高的碳水化合物含量可能与嗜热性的分子基础有关。
