Multiple Monohydroxylation Products from rac-Camphor by Marine Fungus Botryosphaeria sp. Isolated from Marine Alga Bostrychia radicans

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-hydroxycamph...
