delta7- and delta5,7-Sterols are converted to the corresponding delta5-sterols by Phytophthora cactorum. When delta7-sterols were supplied to the fungus, delta5- and delta7-sterols were recovered in an acetone extract of the mycelium, the proportion of delta5-sterol being higher in the free sterol fraction than in the esters. When delta5,7-sterols were supplied, delta5-sterols were recovered. No delta5,7-sterols were found in the mycelium. The initial rate of uptake of the sterols was in the order delta5 greater than delta7 greater than delta5,7.
δ7-甾醇和δ5,7-甾醇被恶疫霉转化为相应的δ5-甾醇。当向该真菌提供δ7-甾醇时，在菌丝体的丙酮提取物中回收了δ5-甾醇和δ7-甾醇，游离甾醇部分中δ5-甾醇的比例高于酯类中的比例。当提供δ5,7-甾醇时，回收了δ5-甾醇。在菌丝体中未发现δ5,7-甾醇。甾醇的初始摄取速率顺序为δ5＞δ7＞δ5,7。
