Figure 7From: Cloning of the cytochrome p450 reductase (crtR) gene and its involvement in the astaxanthin biosynthesis of Xanthophyllomyces dendrorhousRP-HPLC analysis of carotenoids from wild type (UCD 67–385, CBS-6983) and transformant (T13 ( crtRΔBsiWI::hph/ crtR+), CBSTr ( crtRΔNdeI::hph)) strains. Numbers indicate different carotenoids as follows: 1: astaxanthin; 2: phoenicoxanthin; 3: canthaxanthin; 4: hydroxy-keto-γ-carotene; 5: keto-γ-carotene; 6: hydroxy-echinenone; 7: echinenone; 8: lycopene; 9: neurosporene; 10: γ-carotene and 11: β-carotene. In the upper right of the chromatogram, colony phenotype is shown.Back to article page
