Variations in the Lipid Compositions and in the Lipid Molecular Species ofLipomyces starkeyiCultivated in the Glucose Sufficient and the Glucose Deficient Media

Abstract

The lipid compositions, fatty acid compositions, positional distributions of fatty acids in glycerides, and molecular species of phospholipids of L. starkeyi, cultured in the glucose sufficient and the glucose deficient media were compared. Under the glucose sufficient condition, the triglyceride content increased, accompanied by the remarkable increase of C16:0–C18:1–C18:0. The phospholipid content also increased with the variations of the compositions of molecular species in phosphatidylethanolamine and phosphatidylcholine. Under the glucose deficient condition, the triglyceride content remarkably decreased, especially in C18:1–C18:1–C18:1. The compositions of phospholipid molecular species were considerably different from those of the glucose sufficient condition.
