Biotransformation of Aristolane- and 2,3-Secoaromadendrane-Type Sesquiterpenoids Having a 1,1-Dimethylcyclopropane Ring by <i>Chlorella fusca</i> var. <i>vacuolata</i>, <i>Mucor</i> Species, and <i>Aspergillus niger</i>
Biotransformation of the aristolane-type sesquiterpene hydrocarbon (+)-1(10)-aristolene (1) from the crude drug Nardostachys chinensis and of the 2,3-secoaromadendrane-type sesquiterpene lactone plagiochilide (2) from the liverwort Plagiochila fruticosa by three microorganisms, Chlorella fusca var. vacuolata, Mucor species, and Aspergillus niger was investigated. C. fusca var. vacuolata and Mucor sp. introduced
