Abstract

Summary: Lipids from the autotrophic thermophilic archaeobacterium grown under aerobic and anaerobic conditions were analysed and compared with those of , a related micro-organism. The ether lipids of aerobically and anaerobically grown , as well as those of , had the same general features except for the degree of cyclization of the C isopranic chains. The quinone content of was strongly affected by growth conditions. Aerobically grown cells contained caldariellaquinone, 6-(3,7,11,15,19,23-hexamethyltetracosyl)-5-methylthiobenzo[]thiophen-4,7-quinone (83% of the quinone pool), sulfolobusquinone, 6-(3,7,11,15,19,23-hexamethyltetracosyl)-5-methyl-benzo[]thiophen-4,7-quinone (16%) and the tricyclic quinone benzo[1,2-b; 4,5-b']dithiophen-4,8-quinone (trace amounts). In anaerobically grown sulfolobusquinone was the only quinone present.
