Reference Reading
1. The lipids of the rumen fungus Piromonas communis
P Kemp, D J Lander, C G Orpin J Gen Microbiol. 1984 Jan;130(1):27-37. doi: 10.1099/00221287-130-1-27.
The major phospholipids of the anaerobic rumen phycomycete Piromonas communis were phosphatidylethanolamine (38%), phosphatidylcholine (26%) and phosphatidylinositol (13%); no sphingolipids, glycolipids, plasmalogens or phosphonyl lipids were detected. Free fatty acids, triacylglycerols, 1:2 diacylglycerols and a variable amount of 1:3 diacylglycerol were identified, as were minor amounts of squalene and a triterpenol which is probably tetrahymanol. Approximately half the fatty acids were straight chain, even 12 to 24 carbon, saturated acids, the remainder being even 16 to 24 carbon, mono-unsaturated fatty acids. The double bonds in all except the 16 carbon acid were in the omega 9 position. The unsaturation is introduced by a delta 9 desaturase which uses stearic acid as substrate and which does not use oxygen as a terminal electron acceptor. 14C from acetate and glucose was incorporated into the fatty acids of all complex lipids, as were lauric, myristic, palmitic, stearic and oleic acids. [14C]Choline was incorporated into phosphatidylcholine and [14C]ethanolamine into phosphatidylethanolamine and phosphatidylcholine. Label from [14C]serine was recovered in phosphatidylserine and phosphatidylethanolamine, but was not detected in phosphatidylcholine.
2. Butylated Hydroxyanisole-Induced Changes in Lipid Synthesis by Tetrahymena pyriformis 1
J G Surak J Food Prot. 1980 Aug;43(8):603-607. doi: 10.4315/0362-028X-43.8.603.
The effect of butylated hydroxyanisole (BHA) on synthesis of the major lipid classes was studied using Tetrahymena pyriformis as a model cellular system. Initial changes in the amount of lipids were observed after 3 h of exposure to the antioxidant. After 24 h of exposure to increasing concentrations of BHA, there were significant differences in the percentage of [14C]acetate incorporated into various lipid classes with a decrease in the percentage of polar lipids synthesized and an increase in the percentage of triglycerides, free fatty acids and tetrahymanol synthesized. Addition of BHA at a concentration up to 12.5 μg/ml resulted in inhibition of the synthesis of lipid fractions. In addition, the carrier used to add the antioxidant to the test culture had an effect on the cellular toxicity of the antioxidant. Dimethylsulfoxide reduced the toxicity of BHA when compared to ethanol. These results suggest that BHA will alter the relative rates of synthesis of various lipids in T. pyriformis , thus altering the lipid composition of the cell.
3. Lipid modification during cytodifferentiation of Tetrahymena vorax. Whole cell phospholipids and triacylglycerols of microstomal and macrostomal phenotypes
P E Ryals, H E Buhse Jr, J Modzejewski Biochim Biophys Acta. 1989 Jun 27;991(3):438-44. doi: 10.1016/0304-4165(89)90070-6.
Microstomal cells of the ciliate Tetrahymena vorax V2S can be induced to undergo cytodifferentiation to form an alternate phenotype known as the macrostomal cell; however, sublines of T. vorax exist that respond differently to methods that induce macrostomal cell formation. The phospholipid- and triacylglycerol-bound fatty acid compositions of microstomal and macrostomal cells of a high-transforming subline (designated 3-C) were determined and compared to similar data from cells of a low-transforming subline (designated Ala). Differences in fatty acid composition were found between the two phenotypes as well as between the different sublines. Some change in the distribution of radioactive acetate and lauric acid into phospholipid classes of the different subline was observed, and evidence was also obtained that indicated changes in the relative amounts of the sterol-like pentacyclic triterpenoid tetrahymanol. A limited analysis of the lipid composition of stomatin revealed the presence of small amounts of tetrahymanol, phospholipid and free fatty acid. Stomatin is the naturally produced material obtained from T. pyriformis that triggers differentiation in T. vorax. The existence of a low-transforming subline provides a powerful experimental tool for elucidating the underlying biochemical and molecular mechanisms that control cytodifferentiation in T. vorax and possibly in other eukaryotic cells.
