生物合成

Anise oil is a natural spice in Guangxi. Isolation of trans-anethole degrading bacterial strains and trans-anethole biotransformation process were performed using anise oil as the only carbon source. The target strains were expected to produce high value-added nature spice and medicine intermediate by biotransformation of trans-anethole—the main constituent of anise oil. Bacteria were isolated from soil under aniseed trees by enrichment culture.
