sp. nov., a lipolytic yeast species from food and food-related environment Free

Abstract

Two conspecific yeast strains, which based on DNA sequence comparisons represented an undescribed species in the order Trichosporonales were isolated during two independent studies in Hungary and France. One of them (NCAIM Y.02224) was recovered from minced pork in Hungary while the other one (UBOCC-A-218003) was isolated from the air of a dairy plant in France. The two strains shared identical nucleotide sequences in the D1/D2 domain of the nuclear large subunit (LSU) rRNA gene and in the internal transcribed spacer (ITS) region. Analysis of the concatenated DNA sequences for the ITS region and D1/D2 domain of the LSU rRNA gene indicated that the novel species belongs to the recently erected genus . According to sequence comparisons and phylogenetic analysis, the novel species is most closely related to (formerly ), which is often associated with humans and warm-blooded animals. The physiological characteristics of this novel species are also very similar to that of . The only clear-cut difference is that, unlike , the novel species does not utilize imidazole as a nitrogen-source. The species name sp. nov. is proposed to accommodate the above-noted two strains.
