Abstract
- (+)-gamma-Carboxymethyl-gamma-methyl-Delta(alpha)-butenolide was isolated from resting-cell cultures of Pseudomonas desmolyticum incubated in the presence of 5-methylsalicylic acid. 2. The structure of this metabolite was deduced from physical and chemical evidence. 3. The isolated compound must be formed in an enzymic reaction since it shows optical activity. 4. The degradative pathway of 4-methylcatechol by Ps. desmolyticum is discussed.
摘要
- （+）-γ-羧甲基-γ-甲基-Δ（α）-丁烯内酯是从在5-甲基水杨酸存在下培养的解朊假单胞菌的静息细胞培养物中分离得到的。2. 该代谢产物的结构是根据物理和化学证据推导出来的。3. 分离出的化合物必定是在酶促反应中形成的，因为它具有旋光性。4. 讨论了解朊假单胞菌对4-甲基邻苯二酚的降解途径。
