In this work, the photoprotective role of carotenoids in yeasts was analysed by contrasting the responses to UV-B of pigmented and naturally occurring albino strains of Sporobolomyces ruberrimus and Cystofilobasidium capitatum in different conditions. Albino and pigmented strains were confirmed to be conspecific by PCR fingerprinting and rDNA sequencing. Experimental exposure to UV-B conducted with both yeast species showed that the pigmented strains were more tolerant to UV-B than the albino strains and that the increment in carotenoid contents during the stationary growth phase enhance survivorship. These results indicated that carotenoid pigments afford UV-B protection in yeasts. (C) 2009 Elsevier B.V. All rights reserved.
