Abstract: A fungus was isolated from forest soil by selective enrichment method with Δ3-carene as a sole source of carbon and identified as Penicillium nigricans. The isolate was capable of transforming Δ3-carene into neutral [dihydrocarvone, carvone, carveol, (+)-trans-p-mentha-5,8-dien-2-ol and (+)-trans-p-mentha-5,8-dien-2-one] and acidic (perillic acid and 2-hydroxy-p-menth-8-ene-7-oic-acid) metabolic compounds. These compounds were identified based on infrared (IR), proton nuclear magnetic resonance (1H NMR) and mass spectrum (MS) studies. Three pathways have been proposed for the transformation of Δ3-carene into the neutral and acid metabolic compounds based on the study of oxygen consumption by Δ3-carene grown fungal cells. As the different metabolic intermediates of Δ3-carene are much used in the perfume industry, the Δ3-carene, which is abundantly available, can be used as a starting material in the perfume industry by microbial techniques, using this fungal strain.
