Abstract

Three teleomorphic ascomycetous yeast isolates (TA11TR-1T, TA11TR-4 and TA11TR-6) from orchard soil from Tai'an, Shandong province, China, were shown to represent a novel species within the genus Kazachstania based on phenotypic characterization and sequence analyses of the 18S rRNA gene, internal transcribed spacer (ITS) regions and 26S rDNA gene D1/D2 domain. The name Kazachstania taianensis sp. nov. (type strain TA11TR-1T =AS 2.4160T =CBS 11405T) is proposed. K. taianensis sp. nov. clustered in a branch together with Kazachstania sinensis, Kazachstania naganishii and the Kazachstania telluris complex with moderate bootstrap support in the neighbour-joining tree reconstructed from combined 18S and D1/D2 sequences. The novel species possessed unusual ITS 1 (338 bp) and ITS 2 (488 bp) sequences. The total length of the ITS–5.8S rDNA gene region of the species was 983 bp, being much longer than those of other ascomycetous yeast species described so far.
