Biocatalytic reduction of (+)-carvone and (−)-carvone in submerged cultures of the fungi Penicillium citrinum and Fusarium oxysporium

Abstract

Biocatalytic transformation represents a green approach to the asymmetric hydrogenation of activated alkenes. This paper details catabolic events after the addition of (−)-carvone or (+)-carvone to submerged cultures of Penicillium citrinum and Fusarium oxysporium. These microorganisms were shown to biotransform the isomers of carvone, leading to the formation of a diastereoisomeric excess of derivatives of carvone and reduced carveols, and also to isomerize both dihydrocarvone, and their derivatives dihydrocarveols.
