Pre-grown mycelia of Lasiodiplodia theobromae ATCC 28570 transform β-ionone (1) into a large variety of metabolites, by mainly degrading the side-chain of the β-ionone molecule by a C2-unity. The enzyme system responsible for this degradation is proposed to be an oxygenase, which gives rise to the formation of the main product β-cyclo-homogeraniol (8) in analogy to a Baeyer- Villiger oxidation.

拉氏单胞菌ATCC 28570的预先生长的菌丝体主要通过C 2统一降解β-紫罗兰酮分子的侧链,从而将β-紫罗兰酮(1)转变为多种代谢产物。有人提出负责这种降解的酶系统是一种加氧酶,它类似于Baeyer- Villiger氧化反应,导致形成了主要产物β-环-香薄荷醇(8)。Lasiodiplodia的进一步酶促作用,例如氢化和羟基化,导致一些尚未描述的β-紫罗兰酮代谢物的积累。
