BULLERA DERXII SP. NOV. AND BULLERA PSEUDOALBA SP. NOV. ISOLATED FROM DEAD LEAVES OF ORYZA SATIVA AND MISCANTHUS SINENSIS

Abstract

Seven strains of ballistospore-forming yeasts isolated from dead leaves of Oryza sativa L. and Miscanthus sinensis Anderss. were found to represent two new species of the genus Bullera and are described as Bullera derxii Nakase et Suzuki and Bullera pseudoalba Nakase et Suzuki. These yeasts showed some resemblance to Bullera alba in their physiological and biochemical characteristics and DNA base composition. Comparison of the electrophoretic mobilities of six kinds of enzymes clearly demonstrated the differences in these three species.
