When cultured in stirred fermentors the yeast Candida bogoriensis produces extracellular glycolipids in yields of 0.5 to 1 g/l. The principal component of these is a crystalline sophorosyl hydroxy fatty acid, the structure of which has been established as 13-[(2′-O-β-D-glucopyranosyl-β-D-glucopyranosyl)-oxy]docosanoic acid 6′,6″-diacetate. The hydroxy acid portion of the molecule probably has the L-configuration. A monoacetyl glycolipid is also present as a minor component.
当酵母Candida bogoriensis在搅拌发酵罐中培养时,产生外源性的糖脂类化合物,产量为0.5至1克/升。其中的主要成分是一种结晶的sophorosyl羟基脂肪酸,其结构已被确定为13-[(2'-O-β-D-葡萄糖苷基-β-D-葡萄糖苷基)-氧基]十二酸6',6"-二乙酸酯。分子中的羟基酸部分可能具有L-构型。还存在一种单乙酰糖脂作为次要成分。
