【 摘 要 】

Lipid extract and fatty acid composition of cane molasses and yeasts (Saccharomyces cerevisiae M-300-A and Saccharomyces uvarum IZ-1904) grown in molasses medium were determined. In molasses, linoleic acid was found in higher levels (around 42%) and was followed by palmitic, oleic and linolenic acids. The lipid extract varied from 1.02 to 3.13 gkg-1. In yeasts, the level of lipid extract varied from 16.65 to 31.12 g.kg-1 (dry matter basis) depending on the molasses type and yeast species. Both yeasts were able to incorporate fatty acids from molasses' and therefore linoleic and palmitic acids were the major fatty acids found in them.
