To investigate the potential of matrix-assisted laser desorption ionization mass spectrometry (MALDI-TOF/MS) as a platform to support biodiversity and phylogenetic studies of psychrophilic yeasts in cold environments, the technique was employed to rapidly characterize and distinguish three psychrophilic yeasts (Rhodotorula mucilaginosa, Naganishia vishniacii, and Dioszegia cryoxerica) from three mesophilic counterparts (Saccharomyces cerevisiae Cry Havoc, S. cerevisiae California V Ale, and S. pastorianus). A detailed workflow for providing reproducible mass spectral fingerprints of low molecular weight protein/peptide features specific to the organisms studied is presented. The potential of this approach as a tool in the study of biodiversity, systematics, and phylogeny of psychrophilic microorganisms is highlighted.
