The aim of this master’s thesis was focused on characterization of carotenogenic yeast using molecular techniques. For this usage, interspecific variables of strongly conserved sequences of genomic DNA, especially rDNA D1/D2 large ribosomal subunit and ITS1 and 5,8-ITS2 rDNA regions were amplified. These sequences were subjected analysed by DGGE method, which approved differences of S. roseus in all analyzed rDNA sequencies compared to the other analyzed carotenogenic yeasts. Parameters of PFGE and isolation procedure of the intact DNA were optimized for caryotypic yeast characterization. At all, nine of carotenogenic yeast strains Rhodotorula, Sporobolomy-ces, Cystofilobasidium a Phaffia were analyzed by this techniques. Further part of this thesis was focused to application of molecular methods to analysis of region D1/D2 of large ribosomal subunit in mutant carotenogenic yeast strains. Mutant strains were pre-viously adapted to waste substrates - pasta and glycerol, and stability of their production properties was verified.
