外文摘要：Five lipid-producing yeast strains, CHC08, CHC11, CHC28, CHC34, and CHC35, were revealed by Sudan Black В staining to contain lipid droplets within cells. Molecular analysis demonstrated that they were 2 strains of Candida parapsilosis, Pseudozyma parantarctica, Pichia manshurica, and Pichia occidentalis. Following batch fermentation, P. parantarctica CHC28 was found to have the highest biomass concentration, total lipids and lipid content levels. The major fatty acids in the lipids of this yeast strain were С16 and С18. Predictions of the properties of yeast biodiesel using linear equations resulted in values similar to biodiesel made from plant oils. Preliminary production of yeast biodiesel from P. parantarctica CHC28 was accomplished throughesterification and transesterification reactions. It was found that yeast lipids with high acid value are easily converted to biodiesel at an approximately 90% yield. Therefore, it is possible to use crude lipids as alternative raw materials for biodiesel production.
