摘要：
Two strains, 1Y129 and 3Y383, which represent a single novel anamorphic yeast species, were isolated from the Arabian Gulf surrounding Qatar. The two strains have identical sequences in the D1/D2 domains of the large subunit (LSU) and the internal transcribed spacer (ITS) regions of the rRNA gene. On the basis of this sequence analysis the two strains were found to be closely related to Cystobasidium slooffiae CBS5706(T) with 97. 3 % nucleotide substitutions (12 nt; four gaps) in D1/D2 regions of the LSU rRNA and 97.0 % nucleotide substitutions (14 nt; two gaps) in ITS regions. In contrast to Cystobasidium halotolerans sp. nov., the related species Cystobasidium slooffiae, Cystobasidium minutum and Cystobasidium fimetarium were unable to assimilate D-galactose, soluble starch, galactitol, methanol or nitrate, and grew at 37 degrees C. The name proposed for this undescribed species is Cystobasidium halotolerans sp. nov. The ex-type strain is QCC/Y31/17 (=MUCL057192=CGMCC2.5570).
