As a relatively prolific producer of GLA, the strain of Mucor sp LB-54 was selected for a study at different growth temperatures in shaker flask culture. The strain used in our experiment was capable to accumulate a relatively high amount of intracellular lipid, 20.73 % of dry cell weight, and GLA content of 15 % of total fatty acids after 5 days of incubation at 28°C. As the growth temperature was decreased from 28 to 12°C the percentage of GLA increased from 15 to 24 % of total fatty acids. In order to optimize the culture conditions for rapid biomass production and lipid production with a high proportion of GLA, the fungus was grown at two temperature combinations associated supplies of carbon source (glucose) in the culture medium. Maximal production of GLA (74 mg/l) was obtained from the Mucor sp LB-54 strain after 5 days of incubation at 28°C in basal medium following glucose addition (7 % w/v) and incubation for an additional 3 days at 12°C. The identity of GLA found in the strain of Mucor sp LB-54 was confirmed by the coupled gas chromatography-mass spectrometry

The lipid and fatty acids of the Pacific oyster, Crassostrea gigas, collected both in Japan and France, were analyzed. Triacylglycerols and sterols were the major classes in the neutral lipids of both populations of C. gigas between the two countries, and they had signifi cant levels of phospholipids (phosphatidylethanolamine and phosphatidylcholine) with ceramideaminoethylphosphonate in their polar tissue lipids. The differences of 18:3n-3 and 22:6n-3 (docosahexaenoic acid; DHA) levels in the depot triacylglycerols suggest the infl uence of dietary phytoplankton in different environments of the two countries. Although the levels of the fatty acids slightly differed, that of 20:5n-3 (icosapentaenoic acid; EPA, 20.5-24.8%) in the triacylglycerols was specifi cally the highest fatty acid in all the samples. The major polyunsaturated fatty acids in the polar lipids of all samples were EPA (13.2-17.8% for phosphatidylethanolamine and 13.4-22.7% for phosphatidylcholine) and DHA (18.9-26.8% for phosphatidylethanolamine and 13.1-22.5% for phosphatidylcholine). The fl uctuation of total PUFA levels in the polar lipids between samples of both countries suggests the infl uence of diet. In addition, the consistently high EPA levels in the phospholipids may compensate for the variation in DHA levels.

“…In humans and other mammals it is preessential fatty acid. GLA is a precursor of prostaglandins and also is essential for patients who suffer from diabetes, cancer, aging and viral infection [3][4][5] . GLA rich acyl glycerides have been applied directly in the treatment of certain skin related and other diseases such as multiple sclerosis 6 ) , rheumatoid arthritis 7 ) and pre-menstrual syndrome 8) .…”

This study evaluated the effects of dietary supplementation of g-Linolenic acid (18:3n-6, GLA) on the lipid profile of serum and other tissues of rats fed erucic acid (C22:1) rich oil like mustard oil. The rats were fed diet containing 20% mustard oil as erucic acid rich oil and 20% groundnut oil as dietary fat. These groups were kept as reference groups. Another group fed diet containing 20% fat to which evening primrose oil as a source of GLA was blended with mustard oil and groundnut oil at 5% level. The feeding experiment was done for 4 weeks. In another set mustard oil fed group was kept as control while the experimental group was fed evening primrose oil as a source of GLA blended with mustard oil at 2.5% level. The feeding experiment was carried out for 12 weeks. The other dietary components remained same for all the groups. After the scheduled feeding period, it was found that there was no significant change in weight gain, food intake and food efficiency ratio. It was found that dietary GLA resulted in significant decrease in serum triglyceride (TG) and very low density lipoprotein (VLDL) cholesterol and significant increase in high density lipoprotein (HDL) cholesterol in serum in the experimental group. In liver total cholesterol (TC) is significantly higher and in heart and liver TG is significantly lower in GLA fed group.
