Astaxanthin Synthesis by Yeast Xanthophyllomyces dendrorhous and its Mutants on Media Based on Plant Extracts

Abstract:
The study evaluated the effect of media based on plant extracts: potato, carrot and barley malt broth, on growth and astaxanthin synthesis by yeast Xanthophyllomyces dendrorhous DSM 5626 and its mutants. The carrot medium promoted carotenogenesis most effectively. In cultures on this medium the highest volumetric and cellular concentrations of astaxanthin were recorded for four out of five tested strains. Also the share of astaxanthin in the total carotenoids produced by the tested strains was the highest.
