Abstract/OtherAbstract:
The genus Saccharomyces comprises very closely related species. This high degree of relationship makes a simple identification and differentiation of strains difficult since these species are hardly discriminable by their morphological and physiological features. A sequence analysis of ribosomal DNA and the corresponding internal transcribed spacers can only rarely be successfully applied. In this study, we proved the applicability of a novel DNA fingerprinting method, the SAPD-PCR (specifically amplified polymorphic DNA) and of MALDI-TOF-MS (matrix-assisted laser desorption ionization time-of-flight mass spectrometry) fingerprinting with the MALDI Biotyper for the differentiation of species belonging to the genus Saccharomyces. It was possible with SAPD-PCR to create specific banding patterns for all Saccharomyces species. Different strains of the same species produced nearly the same banding patterns. Specific and reproducible reference spectra could be generated for each of the strains with the MALDI Biotyper. Therefore, SAPD-PCR and MALDI-TOF-MS can be fast and reliable tools to identify these related Saccharomyces species which are applied in many biotechnological processes.
