What is Biotransformation of (R)-(+)- and (S)-(−)-citronellol by Aspergillus sp. and Penicillium sp., and the use of solid-phase microextraction for screening about?

The biotransformation of (R)-(+)-and (S)-(-)-citronellol by fungi was studied. For screening experiments, solid-phase microextraction (SPME) was used as analytical sampling technique. It was found that sporulated surface cultures of Aspergillus niger were able to convert the substrate into cis-and trans-rose oxides and nerol oxide. The relative contents in the headspace SPME extract of the three bioconversion products cis-and trans-rose oxide and nerol oxide were up to 54, 21 and 12%, respectively. Rose oxide is found in minor amounts in some essential oils, such as Bulgarian rose oil and geranium oil and contributes to its unique odor. It is one of the most important fragrance materials in perfumery in creating rosy notes. Other bioconversion products were 6-methyl-5-hepten-2-one, 6-methyl-5-hepten-2-ol, limonene, terpinolene, linalool and ␣-terpineol. These bioconversion reactions were confirmed by sporulated surface cultures on larger scale and sampling by dynamic headspace sweep and steam distillation solvent extraction. The same conversions were noticed with A. tubingensis and Penicillium roqueforti. This bioconversion was enantioselective since more of the chiral cis-than tra
