Abstract Calarene was oxidized by Bacillus megaterium and Diplodiagossypina to give allylic calarenols and calarendiols in which either of the geminal methyl groups of the cyclopropane ring was hydroxylated. Globulol was hydroxylated faster and in higher yields than calarene by both strains. In the case of this compound, vicinal diols were formed and, again, either of the geminal methyl groups was
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
