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)
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)
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)
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)
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)
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)
Phenotypic transitions play critical roles in host adaptation, virulence, and sexual reproduction in pathogenic fungi. A minority of natural isolates of Candida albicans, which are homozygous at the mating type locus (MTL, a/a or α/α), are known to be able to switch between two distinct cell types: white and opaque. It is puzzling that white-opaque(More)
Electrophoretic karyotypes of 15 type strains of the taxa in the Candida guilliermondii complex including Candida fukuyamaensis Nakase et al. and Candida xestobii Yarrow et S. A. Meyer were comparatively analysed by using the CHEF (contour-clamped homogeneous electric field) method of PFGE. Eighteen strains (isolated from various natural sources in China)(More)
OBJECTIVE To compare genotypes of Candida albicans strains causing different conditions of vulvovaginal candidiasis (VVC) in Chinese women. METHODS C albicans strains were isolated from the vaginas of patients with different conditions of VVC. The genotypes of the strains were investigated based on single-strand conformation polymorphisms (SSCP) of the(More)
Phylogenetic relationships among the hymenomycetous yeasts in the Cryptococcus luteolus lineage of the Tremellales were examined based on sequence analyses of the 18S rRNA gene, 26S rRNA gene D1/D2 domain, internal transcribed spacer (ITS) region including 5.8S rRNA gene and mitochondrial cytochrome b gene. In addition to the Dioszegia clade, two clades(More)
