Federation of European Microbiological Societies Yeast Research. 6(2):288-297. Interpretive Summary: During design of a gene sequence database for rapid identification of yeasts found in foods and beverages, it was discovered from gene sequence analysis that some of the strains had been misidentified. These strains proved to represent new species and were described as Kregervanrija pseudodelftensis, Saturnispora mendoncae and Candida abiesophila. This report also includes description of the new genus Kregervanrija. Gene sequence analysis provides a rapid, accurate means for identification of food and beverage spoilage yeasts and a means for recognizing new species found in these products.
Technical Abstract: Analysis of nucleotide sequences from domains D1 and D2 of large subunit rDNA demonstrated species of the Pichia fluxuum clade to be phylogenetically isolated, and D1/D2 and ITS rDNA sequence analyses of strains phenotypically identified as P. fluxuum resulted in discovery of three new species. From this work, the following new genus, new species, and new combinations are proposed: Kregervanrija gen. nov.; type species Kregervanrija fluxuum comb. nov. (type strain NRRL YB-4273, CBS 2287); Kregervanrija delftensis comb. nov. (type strain NRRL Y-7119, CBS 2614); Kregervanrija pseudodelftensis sp. nov. (type strain NRRL Y-5494, CBS 10105); Saturnispora besseyi comb. nov. (NRRL YB-4711, CBS 6343); Saturnispora mendoncae sp. nov. (type strain NRRL Y-11515, CBS 5620); Candida abiesophila sp. nov. (type strain NRRL Y-11514, CBS 5366).
