Vanderwaltozyma tropicalis sp. nov., a novel ascomycetous yeast species found in Thailand

摘要

Two strains of yeasts isolated in Thailand were found to represent a novel species of the genus Vanderwaltozyma. These strains are close to V. verrucispora but differ by 13 nucleotides (2.3%) in the D1/D2 domain of the LSU rRNA gene. This difference clearly suggests that the two strains represent a distinct species. It is described as Vanderwaltozyma tropicalis sp. nov. Vanderwaltozyma tropicalis is distinguished from V. verrucispora by the assimilation of trehalose, inability to grow in 0.1% cycloheximide and by higher maximum growth temperature.
