A novel mutant of of the halotolerant unicellular green alga Dunaliella salinia lacks a number of the beta-branch xanthophylls but accumulates zeaxanthin. Biochemical analysis suggests that zeaxanthin substitutes for the beta-branched xanthophylls in the mutant strain. This mutant may provide a biological source for the production of zeaxanthin, a high value bio-product.
