AbstractStationary‐phase cells of a corynebacterium (FUI‐2) and a bacillus (NRRL B‐14864) isolate, when grown aerobically in 1% YE medium at 25°C, converted 12‐hydroxystearic acid to a major compound, 5‐n‐hexyl‐tetrahydrofuran‐2‐acetic acid, and other intermediate and minor compounds (6‐hydroxydodecanoic acid, 4‐hydroxydecanoic acid, 4‐ketodecanoic acid and γ‐decanolactone). The yields of 5‐n‐hexyl‐tetrahydrofuran‐2‐acetic acid, 4‐hydroxydecanoic acid, and γ‐decanolactone, byBacillus lentus NRRL B‐14864 were 43%, 18% and 5%, respectively, after 2.5 d of incubation.
摘要一种棒状杆菌(FUI-2)和一种分离出的芽孢杆菌(NRRL B-14864)的静止期细胞在 25°C 的 1% YE 培养基中进行有氧生长时,可将 12-羟基硬脂酸转化为一种主要化合物 5-正己基-四氢呋喃-2-乙酸以及其他中间和次要化合物(6-羟基十二酸、4-羟基十二酸、4-酮十二酸和γ-癸内酯)。培养 2.5 d 后,猪链球菌 NRRL B-14864 产生的 5-正己基-四氢呋喃-2-乙酸、4-羟基癸酸和 γ-癸内酯的产量分别为 43%、18% 和 5%。
