In this study, the biocatalysis of 18β-glycyrrhetinic acid by two strains of filamentous fungi,
namely Rhizopus arrhizus AS 3.2893 and Circinella muscae AS 3.2695, was investigated …

Biotransformation of lupane-type triterpenoid betulin was carried out with Mucor
subtilissimus CGMCC 3.2456. Yielded nine previously undescribed hydroxylated …

Biotransformation of betulonic acid (1) by Rhizopus arrhizus CGMCC 3.868 resulted in the
production of 16 new (3, 5, 6, and 9–21) and five known compounds. Structures of the new …
