Abstract

Two yeast strains (ST-235 and ST-237) isolated from insect frass collected in northeastern Thailand, were identified as Pichia acaciae and a hitherto undescribed species based on the sequence analysis of the D1/D2 domain of 26S rDNA, ITS regions, and DNA-DNA reassociation experiments. The latter strain, ST-237 (=BCC 11769=NBRC 103638=JCM 12576), was described as Pichia koratensis sp. nov. Pichia koratensis is closely related to Pichia acaciae in the D1/D2 domain sequence of 26S rDNA and phenotypical characteristics but differs by 5 nucleotides (0.9%) from the type strain of P. acaciae and is clearly distinguished by the assimilation and fermentation of sucrose.
