Two novel yeast species were isolated during three independent studies of yeasts associated with natural substrates in Brazil and Taiwan. Analysis of the sequences of the D1/D2 domains of the large subunit rRNA gene showed that these novel species belong to the Wickerhamiella clade. The first was isolated from freshwater and a leaf of sugar cane (Saccharum officinarum) in Brazil and from leaves of Wedelia biflora in Taiwan. Described here as Wickerhamiella slavikovae sp. nov., it differs by 56 nucleotide substitutions and 19 gaps in the D1/D2 region of the large subunit rRNA gene from Candida sorbophila, the least divergent species. The second species, named Wickerhamiella goesii sp. nov., was isolated from leaves and the rhizosphere of sugar cane collected in Rio de Janeiro, Brazil. The species differs by 54 nucleotide substitutions and nine gaps in the D1/D2 domains from Candida drosophilae, its least divergent relative. The type strains are Wickerhamiella slavikovae sp. nov. IMUFRJ 52096(T) (= CBS 12417(T) = DBVPG 8032(T)) and Wickerhamiella goesii sp. nov. IMUFRJ 52102(T) (= CBS 12419(T) = DBVPG 8034(T)).
在三个独立的研究中,从巴西和中国台湾的天然基质中分离到两种新型酵母。对大亚基 rRNA 基因的 D1/D2 结构域序列分析表明,这两种新型酵母属于威克汉姆酵母属(Wickerhamiella)。第一个种是从巴西的淡水和甘蔗叶(Saccharum officinarum)以及中国台湾的三叶鬼针草(Wedelia biflora)的叶子中分离到的。将其描述为斯拉维科夫威克汉姆酵母(Wickerhamiella slavikovae)新种,它与亲缘关系最近的物种,索比菲罗威克汉姆酵母(Candida sorbophila)在大亚基 rRNA 基因的 D1/D2 区有 56 个核苷酸取代和 19 个碱基差异。第二个种,命名为goesii 威克汉姆酵母(Wickerhamiella goesii)新种,是从巴西里约热内卢收集的甘蔗叶及其根际中分离到的。该种与亲缘关系最近的戴氏威克汉姆酵母(Candida drosophilae)在 D1/D2 区有 54 个核苷酸取代和 9 个碱基差异。两个模式菌株分别是斯拉维科夫威克汉姆酵母(Wickerhamiella slavikovae)新种 IMUFRJ 52096(T)(=CBS 12417(T)=DBVPG 8032(T))和 goesii 威克汉姆酵母(Wickerhamiella goesii)新种 IMUFRJ 52102(T)(=CBS 12419(T)=DBVPG 8034(T))。
