Torulopsis bombicola produces extracellular sophorolipids when it is grown on water-insoluble alkanes. Sophorolipids and related model compounds, which were not themselves used for growth, were found to stimulate markedly the growth of T. bombicola on alkanes. This stimulatory effect was restricted to growth on C10 to C20 alkanes, whereas no significantly influence was observed for growth on fatty alcohols, fatty acids, glucose, or glycerol. The nonionic methyl ester of the glycolipid supported the greatest cell yield. However, a number of synthetic nonionic surfactants were unable to replace the glycolipid. When organisms were grown on hexadecane, stimulation of growth by sophorolipids was observed almost exclusively with strains of Torulopsis yeasts. In contrast, the growth of other typical alkane-utilizing yeasts, such as candida and Pichia strains, was inhibited or not affected. It appears that sophorolipids are involved in alkane dissimilation by T. bombicola through an undetermined mechanism.
解脂假丝酵母在水不溶性烷烃上生长时会产生细胞外槐糖脂。槐糖脂及相关模型化合物本身并不用于生长，但发现它们能显著刺激解脂假丝酵母在烷烃上的生长。这种刺激作用仅限于在C10至C20烷烃上的生长，而在脂肪醇、脂肪酸、葡萄糖或甘油上生长时未观察到显著影响。糖脂的非离子甲酯支持最大的细胞产量。然而，许多合成非离子表面活性剂无法替代糖脂。当生物体在十六烷上生长时，几乎仅在解脂假丝酵母菌株中观察到槐糖脂对生长的刺激作用。相比之下，其他典型的利用烷烃的酵母，如念珠菌和毕赤酵母菌株的生长受到抑制或未受影响。似乎槐糖脂通过一种未确定的机制参与解脂假丝酵母对烷烃的异化作用。
