title: Selection of Astaxanthin-Overproducing Mutants of Phaffia rhodozyma with beta-Ionone.
abstract: beta-Ionone, an end ring analog of beta-carotene, inhibits astaxanthin production in the red yeast Phaffia rhodozyma. Astaxanthin-overproducing mutants of this yeast are easily spotted on beta-ionone-containing yeast malt agar plates. beta-Ionone appears to block astaxanthin synthesis at the beta-carotene level.
