During an investigation of olive oil microbiota, three yeast strains were found to be divergent from currently classified yeast species according to the sequences of the D1/D2 domain of the gene encoding for the rRNA large subunit (LSU) and the internal transcribed spacer (ITS) region including the gene for 5.8S rRNA. Phylogenetic analysis revealed that these strains, designated as CBS 12509, 12510T and 12511 respectively, represented a novel anascosporogenous species described herein as Yamadazyma terventina sp. nov.. This new species was placed in the Yamadazyma clade, having as closest relatives Candida trypodendri, Yamadazyma mexicana, Candida conglobata and Candida aaseri. Y. terventina differs from the above mentioned species in the ability to assimilate DL-lactate strongly and ethylamine weakly.

Abstract
During an investigation of olive oil microbiota, three yeast strains were found to be divergent from currently classified yeast species according to the sequences of the D1/D2 domain of the gene encoding for the rRNA large subunit (LSU) and the internal transcribed spacer (ITS) region including the gene for 5.8S rRNA. Phylogenetic analysis revealed that these strains, designated as CBS 12509, 12510T and 12511 respectively, represented a novel anascosporogenous species described herein as Yamadazyma terventina sp. nov.. This new species was placed in the Yamadazyma clade, having as closest relatives Candida trypodendri, Yamadazyma mexicana, Candida conglobata and Candida aaseri. Y. terventina differs from the above mentioned species in the ability to assimilate DL-lactate strongly and ethylamine weakly.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
