Williopsis salicorniae IFO 10733 (type strain), which is characterized by the formation of saturn-shaped ascospores, by the incapability of assimilating nitrate, and by a lower DNA base composition (36.7 mol% G + C), was examined for its partial base sequences of 18S and 26S rRNAs. In the 18S rRNA partial base sequencings, it had an identical base sequence with the type strain of Ogataea glucozyma (identical to Pichia glucozyma, identical to Hansenula glucozyma), which produces hat-shaped ascospores and has the ability to assimilate nitrate and methanol and a higher DNA base composition (45.1 mol% G + C). In the 26S rRNA partial base sequencings, the base differences were four, and the percent similarity was 87 between the type strains of the two species. The data obtained are discussed phylogenetically and taxonomically.
盐角草毕赤酵母IFO 10733（模式菌株），其特征在于形成土星形子囊孢子、不能同化硝酸盐以及较低的DNA碱基组成（36.7摩尔% G + C），对其18S和26S rRNA的部分碱基序列进行了检测。在18S rRNA部分碱基测序中，它与产帽形子囊孢子、能够同化硝酸盐和甲醇且具有较高DNA碱基组成（45.1摩尔% G + C）的解脂奥默酵母（等同于嗜糖毕赤酵母、等同于糖化汉逊酵母）模式菌株具有相同的碱基序列。在26S rRNA部分碱基测序中，两个物种模式菌株之间的碱基差异为4个，相似性百分比为87。对所得数据进行了系统发育和分类学讨论。
