The phylloplane is a term for the aboveground surface of plants and usually refers to the external surface of plant leaves, a dominant aerial part of plant. It is known to be colonized by a large number of microorganisms including bacteria, yeasts and fungi. Yeasts in phylloplane belong to either phylum Ascomycota or phylum Basidiomycota. In this study diversity of yeasts in the external surfac...

This paper reviews the results of an extensive monitoring study, spanning 20-years of observation from three medical centres in Olsztyn on the dynamics and species diversity of fungi most frequently colonizing the respiratory and digestive systems of humans. The experimental materials were swabs and specimens from the gastrointestinal tract, swabs from the oral cavity and pharynx, as well as sp...

Most small genera containing yeast species in the Pucciniomycotina (Basidiomycota, Fungi) are monophyletic, whereas larger genera including Bensingtonia, Rhodosporidium, Rhodotorula, Sporidiobolus and Sporobolomyces are polyphyletic. With the implementation of the "One Fungus = One Name" nomenclatural principle these polyphyletic genera were revised. Nine genera, namely Bannoa, Cystobasidiopsis...

The yeast Rhodosporidium sp. metabolized 4-chloronitrobenzene by a reductive pathway to give 4-chloroacetanilide and 4-chloro-2-hydroxyacetanilide as the major final metabolites. The intermediate production of 4-chloronitrosobenzene, 4-chlorophenylhydroxylamine, and 4-chloroaniline was demonstrated by high-pressure liquid chromatography. Additional studies with selected metabolites established ...

Investigations of the diversity of culturable yeasts at deep-sea hydrothermal sites have suggested possible interactions with endemic fauna. Samples were collected during various oceanographic cruises at the Mid-Atlantic Ridge, South Pacific Basins and East Pacific Rise. Cultures of 32 isolates, mostly associated with animals, were collected. Phylogenetic analyses of 26S rRNA gene sequences rev...

Rhodosporidium toruloides ATCC 10788 (haploid, A1 mating type) and ATCC 10657 (haploid, A2 mating type) were derived from the same diploid parent strain Rhodotorula glutinis ATCC 90781 and are important strains for metabolic engineering. Draft genome sequences of both strains are reported here. The current assembly of strain ATCC 10788 comprises 61 scaffolds with a total size of 20.75 Mbp and a...
