Thirteen strains referred to six asporogenous yeast species were isolated from soil, dung, and forest humus samples collected in Bhutan. The following species, including two new taxa of Cryptococcus, were recovered: Cryptococcus albidus,Cryptococcus bhutanensis sp. nov., Cryptococcus diffluens,Cryptococcus himalayensis sp. nov., Torulopsis Candida, and Rhodotorula glutinis.

Many yeasts were isolated from natural sources in the tropics and subtropics by enrichment culture technique, using medium which contained a surfactant. The medium was acidified with citric acid. A strain S–10 belonging to the genus Candida was found to produce itaconic acid. Under suitable conditions in shake culture, a mutant derived from this strain produced the acid at about 35 % yield on the basis of glucose supplied.

A hitherto undescribed ballistospore-forming yeast was isolated from Knightia excelsa infected by sooty molds collected in New Zealand. It is characterized by ubiquinone-9 and the lack of xylose in the cells so that it is included in the genus Bensingtonia. This yeast resembles B. intermedia and B. yamatoana but is easily distinguished from these two species by the assimilation of nitrate and lactose and the requirement of pyridoxine. Bensingtonia ingoldii Nakase et Itoh sp. nov. is proposed for ...

During a survey of the mycobiota in the stone chamber of the Takamatsu-zuka tumulus in the village of Asuka, Nara Prefecture, Japan, we isolated 19 yeast strains assigned to the genus Candida from various samples, taken mainly from mouldy spots where the colour of the murals had changed to black, white or another tone, and from viscous gels (biofilms) on plaster walls. The 26S rDNA D1/D2 domain sequence-based phylogeny clearly indicates two groups of isolates. Polyphasic characterization, including ...

Partial sequence comparisons of 18S ribosomal RNA comprising 558 nucleotides in the positions 384-562, 942-1119, and 1419-1623 were used to determine the evolutionary affinities among eleven species of Aspergillus and associated teleomorphs, including five species of the most diverse sect. Ornati, and two species of Penicillium with teleomorphs. The species compared were Eurotium repens, Aspergillus fumigatus, Sclerocleista ornata, Hemicarpenteles paradoxus, H. acanthosporus, Warcupiella spinulosa, ...

Microsporidia are intracellular parasitic microbes, which were once thought to be among early diverging eukaryotes, mainly because they lack mitochondria. However, this evolutionary scheme has been challenged by protein-based molecular phylogenetic studies, which suggest a more recent origin of the Microsporidia which clustered Microsporidia with or within 'true' fungal lineages. However, most of these studies did not include sequences from basal fungal phyla (Chytridiomycota and Zygomycota), and ...

Earlier molecular phylogenetic analyses based on nuclear small subunit ribosomal DNA (nSSU rDNA) suggest that the Zygomycota are polyphyletic within the Chytridiomycota. However, these analyses failed to resolve almost all interordinal relationships among basal fungi (Chytridiomycota and Zygomycota), due to lack of sufficient characters within the nSSU rDNA. To further elucidate the higher-level phylogeny of Zygomycota, we have sequenced partial RPB1 (DNA dependent RNA polymerase II largest subunit) ...

The 18S ribosomal RNA gene sequences of the basidiomycetous yeasts Kondoa malvinella and Rhodosporidium dacryoidum, and an anamorphic yeast Sympodiomycopsis paphiopedili were determined. The 18S rRNA gene of R. dacryoidum IAM 13522 (ex type) revealed the presence of an intron-like region with a length of 404 nucleotides, which is presumably assigned to a group I intron. The phylogenetic tree, including 34 published reference sequences, was inferred from 1493 sites which could be unambiguously aligned. ...

For phylogenetic analysis of the higher fungi, we sequenced the nuclear small subunit rRNA (18S rRNA) gene from Taphrina populina, the type species of the genus Taphrina, and Protomyces lactucae-debilis. The molecular phylogeny inferred from these 2 sequences and 75 sequences from the DNA data bank divided the Ascomycota into three major lineages: the hemiascomycetes, the euascomycetes, and the archiascomycetes, newly described herein. The former two lineages are monophyletic, whereas the archiascomycetes, ...

During a survey of yeast strains having high conversion efficiency to ethanol from cellobiose, 'Ogataea pini' ATCC 28781 and 'Pichia pini' NBRC 1794 were found to be distinct from any known species and from each other by a BLAST homology search using the D1/D2 LSU rRNA gene sequences. The D1/D2 phylogeny showed that 'O. pini' ATCC 28781 and 'P. pini' NBRC 1794 belonged to the Ogataea cluster, whereas a comparison of the ITS 1 and 2 regions sequences showed that the ATCC and NBRC strains each formed ...

Unidentified black spots (or stains) appeared on the plaster walls of the Takamatsuzuka and Kitora Tumuli in the village of Asuka, Nara Prefecture, Japan. Public attention was drawn to the biodeterioration of the colorful 1,300-year-old murals. A total of 46 isolates of Acremonium sect. Gliomastix were obtained from various samples (mainly black spots) of the Takamatsuzuka Tumulus (TT) (sampling period, May 2004–December 2006) and the Kitora Tumulus (KT) (June 2004–May 2007). These isolates were assignable ...

The Zygomycota is an ecologically heterogenous assemblage of nonzoosporic fungi comprising two classes, Zygomycetes and Trichomycetes. Phylogenetic analyses have suggested that the phylum is polyphyletic; two of four orders of Trichomycetes are related to the Mesomycetozoa (protists) that diverged near the fungal/animal split. Current circumscription of the Zygomycota includes only orders with representatives that produce zygospores. We present a molecular-based phylogeny including recognized representatives ...

Using an integrated analysis of phenotypic and genotypic characterizations, a total of 18 isolates of "bristle-like" fungal colonizers of the Kitora and Takamatsuzuka Tumuli, which had been provisionally identified as Phialocephala phycomyces, were here determined to be Kendrickiella phycomyces (Auersw.) K. Jacobs & M. J. Wingf. The 18 isolates consisted of 10 from stone surfaces or viscous gels (biofilms) of the stone chamber interior and adjacent small room, and air in the adjacent small room of the ...

Summary: The sequence of the small subunit nuclear ribosomal DNA (18S rDNA) was determined for seven selected species of the teliospore-forming yeasts and Filobasidiaceae in the basidiomycetous yeasts. A phylogenetic tree, including published reference sequences, was inferred from 1623 sites which could be unambiguously aligned. The molecular phylogeny, using a chytridiomycete as an outgroup, divided the eight basidiomycetous yeasts into two groups which correlated well with both septal ultrastructure ( ...

To determine the phylogenetic placement of the major groups of higher fungi, we sequenced the DNA sequences from the small-subunit ribosomal RNA (18S rRNA) coding regions from Taphrina wiesneri (synonym: T. cerasi) and Saitoella complicata and compared them to 18S rRNA sequences from the oomycetes, chytridiomycetes, zygomycetes, ascomycetes, and basidiomycetes. Here we demonstrate that the ascomycetes have at least two major evolutionary lineages. Taphrina wiesneri and Saitoella complicata form a ...

Evolutionary relationships of the two basal fungal phyla Chytridiomycota and Zygomycota are reviewed in light of recent molecular phylogenetic investigation based on rDNA (nSSU, nLSU rDNA), entire mitochondrial genomes, and nuclear protein coding gene sequences (e.g., EF-1α, RPB1). Accumulated molecular evidence strongly suggests that the two basal fungal phyla are not monophyletic. For example, the chytridiomycete order Blastocladiales appears to be closely related to the zygomycete order Entomophthorales. ...

We analyzed sequence data of the 18S rDNA gene from representatives of nine mycoparasitic or zooparasitic genera to infer the phylogenetic relationships of these fungi within the Zygomycota. Phylogenetic analyses identified a novel monophyletic clade consisting of the Zoopagales, Kickxellales, Spiromyces, and Harpellales. Analyses also identified a monophyletic mycoparasitic-zooparasitic Zoopagales clade in which Syncephalis, Thamnocephalis, and Rhopalomyces form a sister group to a Piptocephalis- ...

Soil color originates mainly from organic matter, iron mineralogy and moisture content. We aimed to find a suitable method to measure soil color sensitively and to evaluate the extent to which the color parameters can be useful for statistically estimating total carbon (C), total nitrogen (N) and active iron (Fe) contents in Japanese agricultural soils. A soil color reader (SPAD-503) was applied to two sample sets: (1) 100 surface soils collected throughout a 0.5-ha paddy field (field scale) and (2) 147 ...
