Two new ascomycetous anamorphic yeast species related to Candida friedrichii — Candida jaroonii sp. nov., and Candida songkhlaensis sp. nov.—isolated in Thailand

摘要

In a study of yeast diversity in Thailand, eight strains of hitherto undescribed anamorphic yeasts were isolated: four from insect frass, two from Marasmius sp. fruiting bodies, one from a flower, and one from jackfruit exudates. Phylogenetic analysis of the D1/D2 domain of 26S ribosomal DNA nucleotide sequences indicated that the eight strains represented two new species related to Candida friedrichii. Genetic separation of the two new species was further supported by DNA–DNA hybridization analysis, which resulted in between-species similarity values of less than 48%, and by electrophoretic karyotyping. The two new species are C. jaroonii sp. nov. (type strain, ST-300T = NBRC 103209T = BCC 11783T = CBS 10790T) and C. songkhlaensis sp. nov. (type strain, ST-328T = NBRC 103214T = BCC 11804T = CBS 10791T).
