Effects of R-(+)-limonene on submerged cultures of the terpene transforming basidiomycete Pleurotus sapidus.
The biotransformation of limonene by the basidiomycete Pleurotus sapidus yielded cis/trans-carveol and carvone as the main products. The transformation period was extended from 4 days after direct addition to 12 days by gas phase addition of the substrate. After 2 days of transformation, 97% of the substrate had accumulated in the mycelium, while only 3% were present in the culture medium. Substrate toxicity led to a decrease of dry matter. Adaptation of the precultures with small amounts of substrate doubled the concentration of carveol and increased the concentration of carvone by a factor of 3-4. Total product concentrations of > 100 mg l-1 were reached.
