Abstract: This manuscript describes the biooxidation of rac-camphor using whole cells of marine-derived fungus Botryosphaeria sp. CBMAI 1197. The main biotransformation products of this monoterpene were achieved via a hydroxylation reaction and occurred with 5 days of rac-camphor incubation. Products were identified by means of gas chromatography mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) data. The major hydroxylated products were 6-endo-hydroxycamphor, 6-exo-hydroxycamphor, 5-exo-hydroxycamphor, 5-endo-hydroxycamphor, 3-exo-hydroxycamphor and 8-hydroxycamphor. The 6-exo-hydroxycamphor was obtained through a retro-aldol reaction when 6-endo-hydroxycamphor was maintained in presence of CDCl3; this isomerization was confirmed by H-1 NMR and GC-MS data.
