Baeyer-Villiger monooxygenases ( BVMOs) are a very well-known and intensively studied class of flavin-dependent enzymes. Their substrate promiscuity, high chemo-, regio-, and enantioselectivity are prerequisites for the use in synthetic chemistry and should pave the way for successful industrial processes. Nonetheless, only a very limited number of industrial relevant transformations are known, mainly due to the lack of BVMOs stability and cofactor dependency. In this review, we focus on novel BVMO-mediated transformations, BVMOs in cascade type reactions, potential industrial applications, and how limitations have been tackled by the community. Special attention will be put on whole-cell immobilization strategies. We emphasize to bridge recent developments in fundamental research to industrial applications.
