Optimization of α-Terpineol production by the biotransformation of R-(+)-limonene and (-)-β-pinene.

The main objective of this work is to present the optimization of the biotransformation of R-(+)-limonene and (-)-β-pinene aiming at the production of α-terpineol by strains of fungal and yeasts previously isolated by our research group using the methodology of experimental design. New optimized experimental data on α-terpineol production by the biotransformation of R-(+)-limonene and (-)-β-pinene using newly isolated microorganisms are reported in this work. Conversion of about 1,700 mg/L was achieved when R-(+)-limonene was used as substrate and the newly isolated strain 05.

Isolation and screening of microorganisms for R-(+)-limonene and (-)-beta-pinene biotransformation.

This work is focused on the biotransformation of R-(+)-limonene and (-)-beta-pinene to bioflavor production. To carry out the present study, 405 microorganisms were tested for their ability to bioconvert the substrates. From the isolated microorganisms, 193 were selected in the prescreening using mineral medium for limonene degradation.
