 Lipids of purple membrane from extreme halophiles and of methanogenic bacteria
Publisher Summary This chapter presents a procedure for the extraction of lipids of purple membrane from extreme halophiles and of methanogenic bacteria. For lipid extraction, cells of Halobacterium… Expand
Polar lipids in phototrophic bacteria of the Rhodospirillaceae and Chromatiaceae families.
The polar lipids of photosynthetic purple bacteria of the genera Chromatium, Thiocapsa, Thiocystis, Ectothiorhodospira, Rhodopseudomonas, Rhodospirillum, and Rhodomicrobium were analyzed.… Expand
Isolation and characterization of C50-carotenoid pigments and other polar isoprenoids from Halobacterium cutirubrum.
The polar acetone-soluble lipids of Halobacterium cutirubrum were found to contain (in addition to the previously reported vitamin MK-8 and retinal) neo-bacterioruberin U, bacterioruberin,… Expand
Polar lipids of an extremely halophilic bacterial strain (R-4) isolated from salt ponds in Spain
Abstract The lipids of an extremely halophilic bacterium, strain R-4, isolated from the salt ponds in Spain at Alicante, were found to contain 93% polar lipids and 7% non-polar lipids. Four major… Expand
Characterization and composition of the purple and red membrane from Halobacterium cutirubrum;.
The purple membrance (bacteriorhodopsin) isolated from cells of Halobacterium cutirubrum grown anaerobically in the light was shown to contain 77% protein and 20% lipils by weight. The protein… Expand
Enzymatic synthesis of C40 carotenes by cell-free preparation from Halobacterium cutirubrum.
[14C]Mevalonate or (14C)isopentenyl pyrophosphate was found to be converted to transphytoene, trans-phytofluene, lycopene, and beta-carotene by a cell-free 270 000 X g supernatant fraction prepared… Expand

The methanogenic bacterium Methanospirillum hungatei GP1 has been shown to contain two unusual phosphoglycolipids (phosphoglycolipid I and phosphoglycolipid II) that account for 64% (by wt.) of the… Expand
Isolation and identification of "bacteriorhodopsin" and minor C40-carotenoids in Halobacterium cutirubrum.
Abstract 1. 1. Lycopersene, lycopene and retinal have been identified in cells of Halobacterium cutirubrum . 2. 2. These compounds were isolated in the pure form by column- and thin-layer… Expand
Effect of nicotine on biosynthesis of C50 carotenoids in Halobacterium cutirubrum.
The major carotenoids in pigmented extreme halophiles are the hydroxylated C50 red pigments bacterioruberin (major, 84%) and monoanhydrobacterioruberin (minor, 14%). When cells of Halobacterium… Expand
Lipid composition ofNeurospora crassa
The lipids ofNeurospora crassa, isolated in pure form from freeze-dried mycelium, were found to contain squalene, sterol esters, triglycerides, free fatty acids, geranylgeraniol, free sterols,… Expand
