Microbial transformation of cedrol

(+)-Cedrol [1] was biotransformed by cultures of Steptomyces griseus ATCC10137 and Bacillus cereus UI 1477 (NRRL B-14591). Metabolites isolated by solvent extraction and chromatography over Si gel and reversed-phase RP-C 18 columns and by preparative tlc, were examined by ms and 1 H-and 13 C-nmr spectroscopy. B.cereus afforded 2S-hydroxycedrol [2] as the only metabolite
