Abstract
The yeast Pityrosporum ovale, a skin saprophyte, will only grow if fatty acids of chain length greater than C(10) are added to the culture medium. 9-Hydroxypalmitic acid is the major product of metabolism of even-carbon-number fatty acids; 9-hydroxystearic acid is also found. The optimum pH for this conversion is pH4.5. The hydroxy fatty acids produced are found bound in a polar form in the aqueous phase of the culture medium. Growth of the organisms is facilitated by presentation of the substrate as a two-phase liquid system.
摘要
卵圆形糠秕孢子菌这种皮肤腐生酵母菌，只有在向培养基中添加链长大于C(10)的脂肪酸时才会生长。9-羟基软脂酸是偶数碳脂肪酸代谢的主要产物；也发现了9-羟基硬脂酸。这种转化的最适pH为4.5。所产生的羟基脂肪酸以极性形式存在于培养基的水相中。以两相液体系统形式提供底物有助于该微生物的生长。
