Abstract

The biotransformation of alpha-pinene to verbenone by resting cells of a Penicillium sp. was studied with the aim of optimizing culture conditions for production of this commercially important flavour compound. The bioconversion process was influenced by a range of culture and buffer parameters. Potato dextrose broth with supplementation of 1% glucose and 0.025% yeast extract of pH 5.75 and a temp. of 30C were determined as the optimal conditions for culture growth. 200 mg (dry wt.) of fungal biomass with 20 mg of alpha-pinene in 100 ml of 0.05M phosphate (pH 7.0) at 30C and 6 h of incubation were found to be optimal buffer conditions for the biotransformation.
