Conversion of (−)-Carvone and (+)-Carvone by a Strain of Aspergillus niger

Abstract

Abstract The conversion of (−)-carvone and (+)-carvone by a strain of Aspergillus niger was studied as one of the series of biochemical reduction of terpenes. (−)-Carvone was found to be reduced essentially to (+)-neodihydrocarveol, although (+)-dihydrocarvone and (+)-isodihydrocarvone were also formed in small amounts, whereas (+)-carvone was converted to (−)-isodihydrocarvone, (−)-isodihydrocarveol, (−)-neoisodihydrocarveol, (−)-dihydrocarvone, (−)-neodihydrocarveol, and (+)-dihydrocarveol, of which the former three were the major products. The metabolic pathways for (−)-carvone and (+)-carvone by the strain of Aspergillus niger are discussed and the results on microbial and chemical reductions of carvone and dihydrocarvone are summarized.
