DNA relatedness among species of the genus Zygosaccharomyces

The extent of nuclear DNA complementarity was determined for members of the genus Zygosaccharomyces . From these comparisons, nine species have been identified: Z. baillii, Z. bisporus, Z. cidri, Z. fermentati, Z. florentinus, Z. mellis, Z. microellipsoides, Z. mrakii , and Z. riuxii. Candida mogii , the proposed anamorph of Z. rouxii , showed low relatedness to all nine species. The recently described Saccharomyces astigiensis and S. albasitensis were conspecific with Z. fermentati , and S. placentae showed high relatedness with Z. rouxii . Growth tests were defined that allow recognition of all Zygosaccharomyces species.
