摘要：

Two yeast strains, DMKU-WBBC14 and UFMG-CM-Y3283, were isolated from soil in Samutprakarn province in the central part of Thailand and from rotting wood in an Amazonian forest site in the Roraima State in Brazil, respectively. The two strains showed identical sequences of the D1/D2 domain of the large subunit (LSU) rRNA gene and different sequences by three nucleotide substitutions of the internal transcribed spacer (ITS) region. Therefore, these two strains represented a single species which was most closely related to Cyberlindnera mengyuniae CBS 10845(T). The nucleotide sequence differences between the two strains of the novel species and the type strain Cyberlindnera mengyuniae CBS 10845(T) were 10 substitutions in the D1/D2 region of the LSU rRNA gene and 46 substitutions in the ITS region. DMKU-WBBC14 and UFMG-CM-Y3283 differed in growth temperature profiles. Moreover, they also exhibited different carbon assimilation profiles and growth temperature profiles from the type strain of Cyberlindnera mengyuniae, CBS 10845(T). The name Cyberlindnera tropicalis f.a., sp. nov. is proposed. The type strain is DMKU-WBBC14(T) (=CBS 14558(T) = TBRC 6562(T)). The Mycobank number is MB 819722.
