Five yeast strains, phenotypically indistinguishable from Yarrowia lipolytica and Yarrowia
deformans, were recovered from different animal-related samples. One strain was isolated from a
bacon processing plant in Denmark, two strains from chicken liver in the USA, one strain from
chicken breast in Hungary and one from minced beef in Hungary. Comparisons of the sequences
of their large subunit rRNA gene D1/D2 domain and the internal transcribed spacer (ITS) regions
revealed that, despite their phenotypic similarity, they represent a novel yeast species of the
Yarrowia clade with Y. deformans being the genotypically closest relative (LSU rRNA gene D1/D2
and ITS region similarity of 97.0 and 93.7 %, respectively). Yarrowia divulgata f.a., sp. nov. is
proposed to accommodate these strains with F6-17T (=CBS 11013T =CCUG 56725T) as the
type strain. Some D1/D2 sequences of yeasts from marine habitats were found in the GenBank
database that were identical to those of the strains of Y. divulgata f.a., sp. nov. Unfortunately, these
strains were not available for our study.
