BULLERA MIYAGIANA, A NEW SPECIES OF BALLISTOSPORE -FORMING YEAST ISOLATED FROM ABIES FIRMA COLLECTED IN JAPAN

抄録

A new species of ballistospore-forming yeast, Bullera miyagiana Nakase, Itoh, Takematsu et Bandoni is described. This yeast was isolated from Abies firma collected at Sendai, a northeast region in Japan. It is characterized by Q-10 as the major ubiquinone, xylose in the cells and high G+C content in DNA, 61.4mol% (calculated from T_m) or 58.9mol% (analyzed by high performance liquid chromatography). These characteristics resemble those of Bullera oryzae, but there is a clear difference between B. miyagiana and B. oryzae in the electrophoretic patterns of enzymes. Practically, B. miyagiana is differentiated from B. oryzae by its assimilation of nitrate, ethanol and ribitol, and its lack of assimilation of ethylamine or L-lysine.
