Cerebrosides of Candida lipolytica yeast

Candida lipolytica yeast was grown batchwise on glucose medium. Cerebrosides were isolated from the sphingolipid fraction of total lipids using column chromatography and separated into two compounds by high-performance thin-layer chromatography. Glucose was detected as the sole sugar constituent in cerebrosides. The fatty acid composition of cerebrosides was characterised by a predominance of saturated fatty acids and by a high proportion of fatty acids with 16 carbon atoms. The dominant fatty acid was h16:0. The principal long-chain base components of both cerebroside species were trihydroxy bases, 18- and 20-phytosphinosine. The unique characteristic of cerebrosides was the presence of a high proportion of sphingosine (one-fourth of the total long-chain bases), which is a common characteristic of mammalian sphingolipids and rarely occurs in yeast cerebrosides. The ceramide moiety profile of cerebrosides is similar to that of epidermal ceramides, which implies a possibility for their application in care cosmetics.
