During a survey of yeasts vectored by migratory birds in the Mediterranean basin, isolations from the cloacae of members of the order Passeriformes collected in Ustica (Italy) were performed. Based on phylogenetic analysis of the D1/D2 domain of the 26S rRNA gene and the internal transcribed spacer ITS1-5.8S rRNA gene-ITS2 region, five yeast isolates clustered in a new lineage within the Microstromatales clade. The DNA sequences of these isolates differed from those of their closest relatives, Jaminaea angkorensis and Jaminaea lanaiensis, by 20 and 25 nt substitutions in the D1/D2 domain and 119 and 131 nt substitutions in the complete ITS region, respectively. In addition, the five isolates showed phenotypic characteristics not observed in their closest relatives, such as the ability to grow at 44 8C and at pH 2.5, which suggests a possible adaptation to the bird gastrointestinal tract. On the basis of the isolation source, phenotypic features and molecular strain typing carried out with randomly amplified polymorphic DNA (RAPD)-PCR and mini-satellite-primed (MSP)-PCR analysis, the five isolates were characterized as five distinct strains of a novel species formally described as Jaminaea phylloscopi sp. nov., with 551B6T (5PYCC 6783 T 5CBS 14087 T ) as the type strain. The Mycobank accession number is MB811984.The Microstromatales represent an order that contains several teleomorphic and anamorphic genera. Among them, the genera Quambalaria and Sympodiomycopsis include the largest number of species, with five and three taxa, respectively, whereas the genus Jaminaea, the latest to be described (Sipiczki & Kajdacsi, 2009) (1991) and, at the time of writing, includes three described species: S. paphiopedili (Sugiyama et al., 1991), S. kandeliae (Wei et al., 2011) and S. yantaiensis (Chen et al., 2013). The genus Jaminaea comprises J. angkorensis (Sipiczki & Kajdacsi, 2009) and J. lanaiensis (Wei et al., 2011). This last species was originally described as Sympodiomycopsis lanaiensis by Mahdi et al. (2008).Recent studies have been focused on the diversity and ecology of ascomycetous yeasts carried by migratory birds (Cafarchia et al., 2006a; Cafarchia et al., 2006b;Francesca et al., 2010Francesca et al., , 2012 During an investigation of fungal diversity associated with cloacae of migratory birds in Ustica, several species of filamentous fungi were isolated and characterized (Alfonzo et al., 2013). Among them, five phenotypically similar isolates were preliminarily classified as basidiomycetous yeasts and stored for further investigation. In the present study, we show that these isolates represent five distinct strains of a novel species of the order Microstromatales.Birds were sampled during the migration from subSaharan areas to Europe in Ustica (388 429 N 138 109 480 E; sample date: 2-4 May 2009) (Alfonzo et al., 2013), an island north of Sicily (Italy) that represents one of the most important stop-over sites in the Mediterranean basin . Animals were captured, ringed and identified following the procedures re...

In this study, the yeast microbiota of naturally fermented black olives made from cv. Gemlik, grown in three different districts of the Çukurova region of Turkey, were investigated. Fermentations were conducted for 180 days in three different brines, including NaCl 10% w/v, NaCl 8% w/v and NaCl 8% w/v added with glucose 0.5%. In total, 223 yeasts were isolated and then identified by PCR-RFLP analysis of the 5.8S ITS rRNA region and sequence information for the D1/D2 domains of the 26S rRNA gene. A broad range of yeast biodiversity was identified, including eight genera and nine species. Candida boidinii (41%), Wickerhamomyces anomalus (32%) and Saccharomyces sp. (18%) were predominant yeasts throughout the fermentations. To a lesser extent, the other species, Candida aaseri, Meyerozyma sp., Zygoascus hellenicus, Pichia kudriavzevii, Schwanniomyces etchellsii and Candida atlantica were also members of the olive-fermenting microbiota. In Tarsus and Bahçe districts C. boidinii and in Serinyol district Saccharomyces sp. were the most frequently identified species. W. anomalus was the most frequently isolated species (by 48% of total yeasts) in NaCl 10% brines. C. boidinii was the most dominant species in the brines, including NaCl 8% and NaCl 8% + glucose 0.5%, with frequencies of 42% and 61%, respectively. At the end of the 180 days of fermentation, total acidity values of the brines were in the range 1.04-8.1 g/l lactic acid.

“…A second factor influencing distribution and population structure could be dispersal. Yeasts could migrate via many avenues, such as wind [42], insect, bird, or other animals [42][43][44][45]. Human mediated-dispersal has been inferred for the S. cerevisiae Wine and Beer lineages and for the S. paradoxus European/SpA lineage [3][4][5]46].…”

Postglacial migration shaped the genomic diversity and global distribution of the wild ancestor of lager-brewing hybrids

et al. 2020

The wild, cold-adapted parent of hybrid lager-brewing yeasts, Saccharomyces eubayanus, has a complex and understudied natural history. The exploration of this diversity can be used both to develop new brewing applications and to enlighten our understanding of the dynamics of yeast evolution in the wild. Here, we integrate whole genome sequence and phenotypic data of 200 S. eubayanus strains, the largest collection known to date. S. eubayanus has a multilayered population structure, consisting of two major populations that are further structured into six subpopulations. Four of these subpopulations are found exclusively in the Patagonian region of South America; one is found predominantly in Patagonia and sparsely in Oceania and North America; and one is specific to the Holarctic ecozone. Plant host associations differed between subpopulations and between S. eubayanus and its sister species, Saccharomyces uvarum. S. eubayanus is most abundant and genetically diverse in northern Patagonia, where some locations harbor more genetic diversity than is found outside of South America, suggesting that northern Patagonia east of the Andes was a glacial refugium for this species. All but one subpopulation shows isolation-by-distance, and gene flow between subpopulations is low. However, there are strong signals of ancient and recent outcrossing, including two admixed lineages, one that is sympatric with and one that is mostly isolated from its parental populations. Using our extensive biogeographical data, we build a robust model that predicts all known and a handful of additional regions of the globe that are climatically suitable for S. eubayanus, including Europe where host accessibility and competitive exclusion by other Saccharomyces species may explain its continued elusiveness. We conclude that this industrially relevant species has rich natural diversity with many factors contributing to its complex distribution and natural history.
