Yeasts and their use in astaxanthin production.

摘要

A yeast strain capable of producing astaxanthin at a level of at least 1000 mu g/g, at a cell dry weight of 2 g/l; such strains are, or can be obtained by mutagenesis/selection from, novel Phaffia rhodozyma strains that are haploid, diploid and/or substantially non-ethanol producing.
