Occurrence of squalene, di- and tetrahydrosqualenes, and vitamin MK8 in an extremely halophilic bacterium, Halobacterium cutirubrun.
The nonpolar (acetone-soluble) lipids of the extremely halophilic bacterium, Halobacterium cutirubrum, were found to consist of red carotenoid pigments (43%) and squalenes (48%) with a small amount of a vitamin K-type quinone. The squalenes were shown by n.m.r. and mass spectra to consist of the fully isoprenoid squalene (S; C(30)H(50)), dihydrosqualene (S(2); C(30)H(52)), and tetrahydrosqualene (S(4); C(30)H(54)) in the ratio of 1.0:0.4:0.1. S(2) probably has one reduced internal isoprenoid group, and S(4) has one internal and one terminal reduced isoprenyl group. The vitamin K-type quinone was shown by n.m.r. and mass spectra to have a C(40) isoprenoid side chain, and is thus identified as menaquinone-8 (MK-8).

Characterization and synthesis of mono- and diphytanyl ethers of glycerol.
The methanolyzed lipids of the extreme halophile, Halobacterium cutirubrum, were separated into glycerol diether and glycerol monoether fractions. The diether was shown by synthesis to be 2,3-di-O-(3'R,7'R,11'R,15'-tetramethylhexadecyl)-sn-glycerol. The monoether fraction was separated by thin-layer chromatography on boric acid-impregnated silicic acid into about equal amounts of alpha- and -isomers. The alpha-isomer was found to be identical with the synthetic 3-O-(3'R,7'R,11'R,15'-tetramethylhexadecyl)-sn-glycerol, and the -isomer was identical with the synthetic 2-O-(3'R,7'R,11'R,15'-tetramethylhexadecyl) glycerol.
