Candida wancherniae sp. nov. and Candida morakotiae sp. nov., two novel ascomycetous anamorphic yeast species found in Thailand.
Seven yeast strains isolated from natural substrates of Thailand were found to represent two novel species of Candida, an ascomycetous anamorphic genus. Three strains, ST-233, ST-259 and ST-260, isolated from insect frass and plant leaves were found to represent a single novel species related to Metschnikowia agaves in a tree based on the D1/D2 domain sequences of the 26S rRNA genes. This species is clearly discriminated from M. agaves by the carbon assimilation patterns and required vitamins. The remaining four strains, ST-18, ST-261, ST-606 and ST-658, isolated from the fruit body of a mushroom, insect frass, decayed jack fruit and an unidentified flower, were found to represent a single species which is related to Candida corydali, a recently described insect-associated species, in a neighbor-joining tree based on the D1/D2 sequences. This species is clearly discriminated from C. corydali by the ability to assimilate propane-1,2-diol and the inability to assimilate glucono-delta-lactone. They are described as Candida wancherniae sp. nov. and Candida morakotiae sp. nov., respectively.
