Microbial transformation of cedryl acetate

Biotransformation is the process which produces new derivative compounds with altered chemical structure by using biological system consisting microorganisms. Biotransformed products have biological interests which give benefits especially in pharmaceutical, chemical and agrochemical industries. In this study, cedryl acetate which is a sesquiterpene was used to undergo biotransform process by using Absidia coerulea, Beauveria bassiana and R3-2sp 17. Method used were preparation of media, inoculation of fungi, and inoculation of substrate, incubation for 5 days and ten days, as well as extraction of fermented cedryl acetate extracts. Lastly, the extracts were analysed by using HPLC in order to identify any biotransformation products. Based on the results, cedryl actate yield biotransformation products by using all of the selected fungi. However, there was a possibility that the peaks appeared in the HPLC chromatogram were the secondary metabolite of the fungi.
