Abstract

Two strains, DMKU-UbN24(1) and DMKU-CPN24(1), of a novel yeast species were obtained from soil and palm oil fruit, respectively, collected in Thailand by an enrichment isolation technique using a nitrogen-limited medium containing glycerol as the sole source of carbon. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics and sequence analysis of the D1/D2 region of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region, the two strains were found to represent a novel species of the genus although the formation of ascospores was not observed. The novel species was related most closely to the type strain of but differed by 5.4 % nucleotide substitutions in the D1/D2 region of the LSU rRNA gene and by 10.3–10.5 % nucleotide substitutions in the ITS region. The name f.a., sp. nov. is proposed. The type strain is DMKU-UbN24(1) ( = BCC 61189 = NBRC 109701 = CBS 13392).
