。[0005] As a result of intensive research in order to find a production method that meets the above objectives, the present inventors have discovered that photosynthetic bacteria were cultured by adding fats and oils containing highly unsaturated fatty acids and/or derivatives thereof to the medium. The following findings regarding lipids were obtained. In other words, the total lipid content of photosynthetic bacteria is 6 on a dry matter basis.
~12% by weight, of which more than 90% is phospholipids; ■ Looking at the fatty acid composition of phospholipids, highly unsaturated fatty acids are high at 10 to 30% by weight; ■ The photosynthetic bacteria used in the present invention The growth rate is extremely fast, and a large amount of bacterial cells can be obtained in an extremely short period of time. The present invention was completed based on the above findings.

17015 was added to the medium shown in Table 1, and 0.0% of an oil or fat (containing 30% potassium docosahexaenoate and 8.4% potassium eicosapentaenoate in the oil) was prepared from fatty acid potassium salt extracted from tuna orbital fat. A 10 liter aerobic culture was carried out at 15° C. in a medium containing 1% and adjusted to pH 7, and the culture was collected by centrifugation and washed to obtain 100 g of bacterial cells. 100 g of the obtained bacterial cells were extracted with a mixed solvent of chloroform:methanol=2:1 to obtain 8 g of extracted lipid. Add 400ml of acetone to the total lipids after this solvent removal.
1 was added, stirred while cooling, and acetone-insoluble components were collected by differential filtration of glycolipids and quinones. The resulting acetone-insoluble matter was dissolved in chloroform, and this solution was then subjected to silica gel column chromatography, which was developed sequentially with chloroform, chloroform:methanol=2:1, chloroform:methanol=1:1, and methanol. Check each fraction obtained by TLC,
We found several target phospholipid fractions,
When they were collected and the solvent was removed, about 7 g of phospholipids were obtained. As a result of TLC analysis, the composition of the obtained phospholipids was determined to be mainly composed of phosphatidylglycerol (70%) and phosphatidylethanolamine (20%), and the polyunsaturated fatty acids that constituted these lipids were 18.5% docosahexaenoic acid. , eicosapentaenoic acid 5.6%.
