Yamadazyma barbieri f.a. sp nov., an ascomycetous anamorphic yeast isolated from a Mid-Atlantic Ridge hydrothermal site (-2300m) and marine coastal waters

Résumé

Two yeast strains that are members of the same species were isolated from different marine habitats, i.e. one from Mid-Atlantic Ridge ocean water samples located in the direct vicinity of black smokers near the Rainbow deep-sea hydrothermal vent and one from Brazilian marine water samples off the Ipanema beach. Strains CLIB 1964(T) and CLIB 1965 are anamorphic ascomycetous yeasts affiliated to the Yamadazyma clade of Saccharomycetales. Interestingly, these strains were phylogenetically and distinctly positioned into a group of species comprising all species of the genus Yamadazyma isolated from marine habitats including deep-sea hydrothermal vents, i.e. Candida atmosphaerica, C. spencermartinsiae, C. atlantica, C. oceani and C. taylorii. These strains differed significantly in their D1/D2 domain sequences of the LSU rRNA gene from the closely related species mentioned above, by 2.6, 3.0, 3.4, 3.8 and 6.0 %, respectively. Internal transcribed spacer region sequence divergence was also significant and corresponded to 4.6, 4.7, 4.7, 12.0 and 24.7% with C. atlantica, C. atmosphaerica, C. spencermartinsiae, C. oceani and C. taylorii, respectively. Phenotypically, strains CLIB 1964(T) and CLIB 1965 could be distinguished from closely related species by their inability to assimilate L-sorbose. CLIB 1964(T) (= CBS 14301(T) = UBOCC-A-214001(T)) is the designated type strain for Yamadazyma barbieri sp. nov. The MycoBank number is MB 815884.
