The lipid fraction of the oil obtained from the yeast Yarrowia
lipolytica LFMB19 comprised more than 80% of neutral lipids that
are suitable for the production of biodiesel. Total lipids included
glycolipids, waxes, phospholipids, etc. which cannot be converted
into methyl esters through transesterification. This would make
necessary the inclusion of lipid pretreatment.
