Abstract

Five dimorphic yeast strains were isolated from rotting lime fruits in Borneo. The sequences of the D1/D2 domains of the 26S rRNA genes, the internal transcribed spacer (ITS) chromosomal regions and the 18S rRNA genes were identical in the isolates and differed from the corresponding sequences of all known yeast species. Based on the sequence differences (12-15% in the D1/D2 domain) from the closest relatives and the different pattern of taxonomic traits, the new isolates are assigned the status of a new species, for which the name Candida citri sp. nov. is proposed. Its type strain is 11-469T, which has been deposited in Centralbureau voor Schimmelcultures (Utrecht, the Netherlands) as CBS 11858T, Culture Collection of Yeasts (Bratislava, Slovakia) as CCY 29-181-1T and the National Collection of Agricultural and Industrial Microorganisms (Budapest, Hungary) as NCAIM Y.01978T. MycoBank number: MB 519100. The GenBank accession numbers for nucleotide sequences of its D1/D2 domain, ITS and 18S regions are HM803241, HM803242 and HM803243, respectively. Candida citri produces invasive mycelium composed of true septate hyphae that grow towards nutrient-rich parts of the medium and develop large vacuoles at the nongrowing ends of their cells. The hyphae produce blastoconidia, which can establish satellite yeast colonies in the invaded solid substrate.
