Abstract Six yeast strains have been isolated and identified from the spruce bark beetle,Ips typographus. We have studied the ability of the yeasts to interconvertcis-verbenol,trans-verbenol, and verbenone. (1S)-cis-Verbenol is an active component in the aggregation pheromone ofIps typographus. The isolatedCandida molischiana/ Hansenula capsulata strain can convert both (1R)- and (1S)-cis-verbenol to verbenone. TheCandida nitratophila strain converts (1R)-cis-verbenol totrans-verbenol and (1S)-cis-verbenol to verbenone. Some of the yeast strains produce 3-methylbutanol, 2-methylpropanol, and 2-phenylethanol after growth in Sabouraud medium.
