Thirteen strains of yeasts typical of the genus Moniliella were isolated from fermenting meat and meat processing tools in Vietnam. PCR fingerprints generated by primer (GAC)(5) subdivided the strains into two distinctive genetic groups. In a phylogenetic tree based on D1/D2 large subunit rRNA gene sequences, the strains formed a well-supported clade with Moniliella spathulata and Moniliella suaveolens but represented two new lineages. The names Moniliella carnis sp. nov. and Moniliella dehoogii sp. nov. are proposed. The two novel species can be distinguished from each other and from known species of Moniliella based on phenotypic characteristics. It is assumed that the yeasts were associated with fatty substances that contaminated the meat processing tools. The type strain of Moniliella carnis is KFP 246(T) ( = CBS 126447(T) = NRRL Y-48681(T)) and the type strain of Moniliella dehoogii is KFP 211(T) ( = CBS 126564(T) = NRRL Y-48682(T)).
从越南发酵肉和肉类加工工具中分离到 13 株属于 Moniliella 属的典型酵母菌株。引物 (GAC)(5) 生成的 PCR 指纹将菌株分为两个不同的遗传群。在基于 D1/D2 大亚基 rRNA 基因序列的系统发育树中，这些菌株与 Spathulata 和 Suaveolens 形成了一个支持良好的分支，但代表了两个新的谱系。提议提出了新种 Moniliella carnis sp. nov. 和 Moniliella dehoogii sp. nov.。这两个新种可以根据表型特征彼此区分开来，并与已知的 Moniliella 种区分开来。据推测，这些酵母与污染肉类加工工具的脂肪物质有关。Moniliella carnis 的模式菌株是 KFP 246(T)（= CBS 126447(T) = NRRL Y-48681(T)），Moniliella dehoogii 的模式菌株是 KFP 211(T)（= CBS 126564(T) = NRRL Y-48682(T)）。
