Candida thermophila sp. nov., a novel thermophilic yeast isolated from soil.

Yeast strain Y94T, which is capable of growth at high temperature, was isolated from soil in Korea. Characteristics of the strain include asexual reproduction by multilateral budding, the absence of extracellular starch-like compounds, a negative Diazonium blue B colour reaction, and the absence of arthrospores, ballistoconidia and ascospores; the strain can therefore be placed in the genus Candida. A maximum growth temperature of 50-51 degrees C, along with certain other physiological characteristics, and a unique 26S rDNA partial sequence separate this strain from other ascomycetous yeasts. Taken together, these results suggest that the strain is a novel species and the name Candida thermophila sp. nov. (type strain is Y94T = JCM 10994T = KCCM 50661T) is proposed.
