| Popis: | The lipids produced by oleaginous microbes are considered sustainable resources for biofuels. To facilitate controlled lipid production and lipid analysis, more efficient lipid extraction methods are required. This study describes the automated pressurized liquid extraction (APLE) method for lipid extraction from dried cells of the oleaginous yeast species Rhodosporidium toruloides and Cryptococcus curvatus. Cells were mixed with diatomite in a mortar, added to the sample chamber, and treated with a mixture of chloroform and methanol at 105 °C. More than 95% lipids were extracted. Analysis by using high-performance thin-layer chromatography showed that the neutral lipid contents in the obtained samples by APLE method were similar to those by the ball milling–assisted extraction method. The lipids had an essentially identical fatty acid composition compared with lipids extracted with the acid-heating extraction (AHE) method. This demonstrated that lipids can be efficiently extracted from oleaginous yeasts in less time and without harsh pretreatment procedures. |
