Metschnikowia sinensis sp. nov., Metschnikowia zizyphicola sp. nov. and Metschnikowia shanxiensis sp. nov., novel yeast species from jujube fruit

Int J Syst Evol Microbiol. 2006 Sep;56(Pt 9):2245-2250. doi: 10.1099/ijs.0.64391-0.

Abstract

Eight yeast strains were isolated from jujube fruit surfaces collected in Shanxi and Shandong Provinces, China. All eight strains produced needle-shaped ascospores under suitable conditions. Three separate groups, representing three novel species in the genus Metschnikowia, were recognized by sequence comparisons of the 26S rDNA D1/D2 domain and internal transcribed spacer (ITS) region. The names Metschnikowia sinensis sp. nov. (type strain XY103(T)=AS 2.3110(T)=CBS 10357(T)), Metschnikowia zizyphicola sp. nov. (type strain XY201(T)=AS 2.3111(T)=CBS 10358(T)) and Metschnikowia shanxiensis sp. nov. (type strain XY801(T)=AS 2.3112(T)=CBS 10359(T)) are proposed for the three novel species. Phylogenetic analysis of the 26S rDNA D1/D2 domain sequence showed that these three novel species are clustered in a clade together with the previously described species Metschnikowia fructicola, Metschnikowia andauensis, Metschnikowia pulcherrima and Metschnikowia chrysoperlae.
