PURPOSE:To obtain polar lipid or neutral lipid having high linolic acid content, by a method wherein a mold of Pellicularia genus is cultivated in a medium containing carbohydrate or vegetable fiber as carbon source, and the lipid is separated or extracted from the cultivated medium. CONSTITUTION:A mold of Pellicularia genus is cultivated in a medium containing carbohydrate or vegetable fiber as carbon source. Then polar lipid such as glycolipid, phospholipid or neutral lipid such as fats and oils having a linolic acid content of 65-79% is recovered from the cultivated medium by means of solvent extraction method. Examples of carbohydrates as carbon source are glucose, sucrose, starch, and molasses. Examples of vegetable fibers are linter pulp, wood pulp, and bagasse. Preferably the cultivation is carried out at a pH of 4.0-6.0 and at a temp. of 15- 38 deg.C for 7-30 days. The cultivation of the mold is carried out in a liquid medium by static culture, shake culture, aerated agitated culture, or the like. |
