A taxonomic study below the generic or at the specific level was made of electrophoretic patterns of seven enzymes in 18 strains of the Q
9-equipped
Sporobolomyces and
Bensingtonia species. The seven enzymes were glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, isocitrate dehydrogenase, malate dehydrogenase, hexokinase, phosphoglucomutase, and fumarase. Seven species,
S. intermedius, S. miscanthi, S.
subroseus, S. yamatoanus, S. naganoensis, S. yuccicola, and
S. phylladus, constituted clusters separate from each other (
s=0 or 14%). The two strains of
S. miscanthi showing identical electrophoretic enzyme patterns (
s=100%) were linked to
Sporobolomyces species NZ-3 with a similarity value of 29%. Within the five strains of
S. yamatoanus examined, the type strain had a similarity value of 86% with one other strain. The remaining three strains whose similarity values were calculated as 100% and 57% were linked to the two strains including the type strain with a similarity value of 43%. The three strains of
S. phylladus had identical electrophoretic enzyme patterns (
s=100%).
Sporobolomyces species NZ-24 had a separate cluster (
s=0%).
Sporobolomyces weijmanii was synonymous with
S. intermedius (
s=100%).
Bensingtonia ciliata constituted its own cluster (
s=0%). These data are discussed from the taxonomic point of view.
