Chang S, Yang L, Huang T, Chen C, Sheu S, Liu P, et al.
Phytochemistry . 2013 Aug; 95:268-76. PMID: 23948258
The biotransformation of dihydroisosteviol with Absidia pseudocylindrospora ATCC 24169, Streptomyces griseus ATCC 10137, Mucor recurvatus MR36, and Aspergillus niger BCRC 31130 yielded 15 metabolites, eight of which were previously unknown....

Yang L, Chang S, Lin W, Chou B, Wang L, Liu P, et al.
Phytochemistry . 2012 Jan; 75:90-8. PMID: 22226038
Fourteen oxygenated compounds were isolated from the preparative-scale biotransformation of isostevic acid (ent-beyeran-19-oic acid). Incubation of it with Aspergillus niger BCRC 32720 produced eight metabolites, four with Bacillus megaterium ATCC...

J Nat Prod . 2011 May; 74(6):1379-85. PMID: 21598928
From the screening of 21 microbial strains, Absidia pseudocylindrospora ATCC 24169 and Aspergillus niger BCRC 32720 were found to reproducibly transform isosteviol lactam (4α-carboxy-13α-amino-13,16-seco-ent-19-norbeyeran-16-oic acid 13,16-lactam) (3) into various compounds....

Phytochemistry . 2009 Apr; 70(6):759-64. PMID: 19394984
A number of hydroxylated diterpenoids were obtained from the microbial transformation of isosteviol lactone (4alpha-carboxy-13alpha-hydroxy-13,16-seco-ent-19-norbeyeran-16-oic acid 13,16-lactone) (2) with Mucorrecurvatus MR 36, Aspergillusniger BCRC 31130, and Absidiapseudocylindrospora ATCC 24169. Incubation...

J Nat Prod . 2008 Feb; 71(4):602-7. PMID: 18275152
Two filamentous fungi, Cunninghamella bainieri ATCC 9244 and Aspergillus niger BCRC 32720, were used to investigate the biotransformation of isosteviol lactone (4alpha-carboxy-13alpha-hydroxy-13,16- seco-ent-19-norbeyeran-16-oic acid 13,16-lactone) ( 2), which was derived...

Phytochemistry . 2007 Jan; 68(4):562-70. PMID: 17207824
Steviol (2) possesses a blood glucose-lowering property. In order to produce potentially more- or less-active, toxic, or inactive metabolites compared to steviol (2), its microbial metabolism was investigated. Incubation of...
