DNA BASE COMPOSITION OF STRAINS IN THE GENERA RHODOSPORIDIUM, CYSTOFILOBASIDIUM, AND RHODOTORULA DETERMINED BY REVERSED- PHASE HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY

Abstract

The DNA base composition of 74 strains in the genera Rhodosporidium, Cystofilobasidium, and Rhodotorula were determined by reversed-phase high-performance liquid chromatography (HPLC). The relative standard error of nucleoside analysis was less than 1%. The differences between the two values determined by the HPLC method and the T_m method were less than 1% in three strains determined in this study and less than 2%, with a few exceptions, compared with reference data.
