The budding yeast, Saccharomyces cerevisiae, is a leading system in genetics, genomics and molecular biology and is becoming a powerful tool to illuminate ecological and evolutionary principles. However, little is known of the ecology and population structure of this species in nature. Here, we present a field survey of this yeast at an unprecedented scale(More)
Three ascomycetous yeast strains, H-6(T), ZX-15 and ZX-20, isolated from the bark of two tree species of the family Fagaceae collected from different regions of China, formed unconjugated and persistent asci containing two to four globose ascospores. 26S rDNA D1/D2 domain and internal transcribed spacer (ITS) region (including 5.8S rDNA) sequence analysis(More)
Lager-brewing arose in 15th century Bavaria [1] and is nowadays the most popular technique for alcoholic beverage production in the world. The technique is characterized by low temperature fermentation using the domesticated yeast Saccharomyces pastorianus (synonym S. carlsbergensis). It has been clear that the lager yeast is a hybrid with one portion of(More)
In an investigation of the yeast biota involved in silage deterioration, a considerable number of strains belonging to Saccharomyces and related genera were isolated from aerobically deteriorating corn silage in Tochigi, Japan. Analysis of sequences of the internal transcribed spacer and the large-subunit rRNA gene D1/D2 domain and electrophoretic(More)
The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in Amsterdam on 19-20 April 2011 under the auspices of the International Commission on the Taxonomy of Fungi (ICTF). The purpose of the symposium was to address the issue of whether or how the current system of naming pleomorphic fungi should be maintained or(More)
Among basidiomycetous yeast strains isolated from wilting leaves of various plants in China, two groups of Pseudozyma strains were distinguished from the others by morphological and physiological characterization. Molecular taxonomic analysis based on sequencing of the large subunit (26S) rRNA gene D1/D2 domain and internal transcribed spacer (ITS) region(More)
BACKGROUND Vulvovaginal candidosis (VVC), which is most frequently caused by Candida albicans, is one of the most common vaginal infections and is a common problem worldwide. Despite the fact that extensive epidemiological studies have been performed, what triggers VVC, especially recurrence of the infection, is still uncertain. METHODS Genotypes of C.(More)
Yeasts are unicellular fungi that do not form fruiting bodies. Although the yeast lifestyle has evolved multiple times, most known species belong to the subphylum Saccharomycotina (syn. Hemiascomycota, hereafter yeasts). This diverse group includes the premier eukaryotic model system, Saccharomyces cerevisiae; the common human commensal and opportunistic(More)
Among the ballistoconidium-forming yeast strains isolated from various plant leaves collected in North and Northeast China, 12 strains forming orange to orange-red colored colonies were revealed to represent four novel species of the genus Sporobolomyces by conventional, chemotaxonomic and molecular phylogenetic studies, based on the 26S-rDNA D1/D2 domain(More)
Two yeast strains, strains XH 1026 and XH 1164, isolated from the sputum of an intensive care unit patient with acute pneumonia, were originally identified as Candida albicans and C. tropicalis, respectively. Sequence analysis of the 26S rRNA gene D1/D2 domain and the internal transcribed spacer (ITS) region indicated that the two strains represent a novel(More)
