BIOTRANSFORMATION OF LIMONENE AND RELATED COMPOUNDS BY ASPERGILLUS CELLULOSAE

Article abstract of DOI:10.1016/0031-9422(92)83619-A

The biotransformation of (+)-, (-)- and (+/-)-limones by Aspergillus cellulosae M-77 has been investigated. (+)-Limonene was transformed mainly to (+)-isopiperperitenone, (+)-limonene-1,2-trans-diol, (+)-cis-carveol and (+)-perilly alcohol, along with the minor formation of isopiperitenol and α-terpineol, whereas (-)-limonene was transformed to (-)-perillyl alcohol, (-)-limonene-1,2-trans-diol and (+)-neodihydrocarveol as the major products, along with the minor products such as (-)-isopiperitenone.In the case of the DL-form, perillyl alcohol, limonene-trans-1,2-diol, isopiperitenone and α-terpineol were also formed. 1-Methylcyclohexene and cyclohexene were also transformed to 3-methyl-2-cyclohexenone and 2-cyclohexenone via the corresponding alcohols, respectively.Key Word Index: Aspergillus cellulosae; biotransformation; (+)-, (-)- and (+/-)-limones; isoperitenone; limonene-1,2-trans-diol; cis-carveol; α-terpineol; 1-methylcyclohexene; cyclohexene; 3-methyl-2-cyclohexenone; 2-cyclohexenone.
