    • The present invention relates to a process for producing a compound (II-a) or a compound (II-b), each of which is a hydroxylated product of a compound represented by the formula (I-a) (hereinafter referred to as compound (I-a)): wherein R1 represents a hydrogen atom, a substituted or unsubstituted alkyl, or an alkali metal, and R2 represents a substituted or unsubstituted alkyl, or a substituted or unsubstituted aryl; or a ring-closed lactone form thereof (hereinafter referred to as compound (I-b)). wherein the process comprises: treating the compound (I-a) or compound (I-b) in an aqueous medium comprising with a microorganism acting to hydroxylate compound (I-a) or compound (I-b), having no ability to sporulate and showing no hyphal growth, a culture of the microorganism, or a treated product of the culture, as an enzyme source; and collecting a hydroxylated product of compound (I-a) or compound (I-b) from the aqueous medium.
    • 本发明涉及一种制备化合物(II-a)或化合物(II-b)的方法,其中每种化合物是由式(Ia)表示的化合物的羟基化产物(以下称为化合物(Ia )):其中R 1表示氢原子,取代或未取代的烷基或碱金属,R 2表示取代或未取代的烷基,或取代或未取代的烷基, 未取代的芳基; 或其封闭的内酯形式(以下称为化合物(I-b))。 其中所述方法包括:在水性介质中处理化合物(Ia)或化合物(Ib),所述水性介质包含微生物作用于羟化化合物(Ia)或化合物(Ib)的微生物,其不具有孢子形成和不显示菌丝生长的能力, 的微生物或培养物的处理产物作为酶源; 并从水性介质中收集化合物(I-a)或化合物(I-b)的羟基化产物。
