COENZYME Q SYSTEM IN THE CLASSIFICATION OF APICULATE YEASTS IN THE GENERA NADSONIA, SACCHAROMYCODES, HANSENIASPORA, KLOECKERA, AND WICKERHAMIA

摘要

Fourty-three cultures of apiculate yeasts were examined for the Co-Q system, which belong to the genera Nadsonia, Saccharomycodes, Wickerhamia, and Hanseniaspora and its imperfect counterpart of Kloeckera. All the species of these genera were found to have the Q-6 system except for the only species of the genus Wickerhamia (Q-9). The results obtained are discussed in connection with other criteria such as PMR spectra of cell wall polysaccharides, DNA base composition, and serological characteristics. Our method is described as a criterion for grouping yeasts and yeast-like organisms.
