厌氧嗜热古细菌岛火杆菌（Pyrobaculum islandicum, Geo 3）检测了脂醌的存在。薄层色谱、高效液相色谱、紫外光谱和质谱分析表明该化合物中含有甲萘醌。未发现2-甲基-3-聚异戊二基-1,4-萘醌环核被取代的证据。然而，C3类异戊二烯链由6个完全饱和的单元组成，表明该生物的主要甲基醌对应于2-甲基-3- vi，V，IV，III，II， i -十二氢六戊烯基- 1,4 -萘醌（MK-6H12）。
The anaerobic, thermophilic archaebacterium, Pyrobaculum islandicum (Geo 3) was examined for the presence of lipoquinones. Thin layer chromatographic, HPLC, UV, and mass spectroscopic analysis showed that a menaquinone was present. No evidence was found for substitution of the 2-methyl-3-polyisoprenyl-1,4-naphthoquinone ring nucleus. However, the C3 isoprenoid chain consisted of six fully saturated units, and shows that the major menaquinone in this organism corresponds to 2-methyl-3-VI,V,IV,III,II,I-dodecahydrohexaprenyl-1, 4-naphthoquinone (MK-6H12).
