Enzymes are a valuable tool for upcycling side-stream from renewable sources. We have found that EstB from Burkholderia gladioli could achieve high enantiopurity in upcycling α-pinene, a side-product from turpentine production, whereas common lipases and esterases could not. This reaction can be easily integrated with the existing chemical synthetic route for the production of the racemic camphor with
酶是对可再生资源副产品进行升级改造的宝贵工具。我们发现,来自唐菖蒲伯克霍尔德杆菌的 EstB可以在升级回收 α-蒎烯(松节油生产的副产品)时获得高对映体纯度,而普通脂肪酶和酯酶则不能。该反应可以很容易地与生产外消旋樟脑的现有化学合成路线整合,因为该路线经过中间体乙酸异冰片酯,因此只需进行最小的调整。
