“…Among them, the 93% belong to Ascomycota Phylum, that includes the almost totality of genera and the totality of new taxa present in the collection (12 species and 6 genera) ( Table 1). One basidiomycetous new species, isolated from soil under moss in Kay Island, Cryptococcus vaughanmartiniae Turchetti, Blanchette & Arenz (CCFEE5495=DBVPG5862), was recently described (Turchetti et al 2015). …”

This dataset includes information regarding fungal strains collected during several Antarctic expeditions: the Italian National Antarctic Research program (PNRA) expeditions “X” (1994/1995), “XII”\ud (1996/1997), “XVII” (2001/2002), “XIX” (2003/2004), “XXVI” (2010/2011), the Czech “IPY Expedition”\ud (2007–2009) and a number of strains donated by E. Imre Friedmann (Florida State University) in 2001, isolated from samples collected during the U.S.A. Antarctic Expeditions of 1980-1982. Samples,\ud consisting of colonized rocks, mosses, lichens, sediments and soils, were collected in Southern and Northern Victoria Land of the continental Antarctica and in the Antarctic Peninsula. A total of 259 different strains were isolated, belonging to 32 genera and 38 species, out of which 12 represented new taxa. These strains are preserved in the Antarctic section of the Culture Collection of Fungi from Extreme Environments (CCFEE), which represents one of the collections associated with the Italian National Antarctic Museum (MNA, Section of Genoa, Italy), located at the Laboratory of Systematic Botany and Mycology, Department of Ecological and Biological Sciences (DEB), Tuscia University (Viterbo, Italy). The CCFEE hosts a total of 486 Antarctic fungal strains from worldwide extreme environments. Distributional records are reported here for 259 of these strains. The holotypes of the 12 new species included in this dataset are maintained at CCFEE and in other international collections: CBS-KNAW Fungal Biodiversity Centre (Utrecht, Netherlands); DBVPG, Industrial Yeasts Collection (University of Perugia, Italy); DSMZ, German Collection of Microorganisms and Cell Cultures (Brunswick, Germany); IMI, International Mycological Institute (London, U.K.)

Antarctica is the coldest, windiest, and driest continent on Earth. In this sense, microorganisms that inhabit Antarctica environments have to be adapted to harsh conditions. Fungal strains affiliated with Ascomycota and Basidiomycota phyla have been recovered from terrestrial and marine Antarctic samples. They have been used for the bioprospecting of molecules, such as enzymes. Many reports have shown that these microorganisms produce cold-adapted enzymes at low or mild temperatures, including hydrolases (e.g. α-amylase, cellulase, chitinase, glucosidase, invertase, lipase, pectinase, phytase, protease, subtilase, tannase, and xylanase) and oxidoreductases (laccase and superoxide dismutase). Most of these enzymes are extracellular and their production in the laboratory has been carried out mainly under submerged culture conditions. Several studies showed that the cold-adapted enzymes exhibit a wide range in optimal pH (1.0-9.0) and temperature (10.0-70.0 °C). A myriad of methods have been applied for cold-adapted enzyme purification, resulting in purification factors and yields ranging from 1.70 to 1568.00-fold and 0.60 to 86.20%, respectively. Additionally, some fungal cold-adapted enzymes have been cloned and expressed in host organisms. Considering the enzyme-producing ability of microorganisms and the properties of cold-adapted enzymes, fungi recovered from Antarctic environments could be a prolific genetic resource for biotechnological processes (industrial and environmental) carried out at low or mild temperatures.

“…[6] with Naganishia globosus as the type species, which was later synonymized with Cryptococcus saitoi based on rRNA gene sequence data [7]. Subsequently, Naganishia was resurrected to accommodate representatives of the albidus clade of the genus Cryptococcus , namely Cryptococcus onofrii and Cryptococcus vaughanmartiniae [4, 5, 8, 9]. The genus Naganishia comprises a variety of asexually reproducing yeast species with different morphological and physiological characteristics and distinct habitats.…”

Two yeast strains representing a novel species in the basidiomycetous yeast genus Naganishia were isolated from flowers of Sorbaria sorbifolia collected in Beijing Olympic Forest Park, PR China. Results of multi-gene phylogenetic analysis indicated that the two strains were closely related to the type strains of Naganishia bhutanensis (CBS 6294T) and Naganishia antarctica (CBS 7687T). However, the new isolates differed from N. bhutanensis CBS 6294T by 1.79 % sequence divergence in the D1/D2 domain (11 nt substitutions and three indels), and 2.42 % (15 nt differences and one indel) to N. antarctica CBS 7687T. In the ITS region, the new isolates showed 1.15 % divergence (7 nt substitutions and one indel) to N. bhutanensis CBS 6294T and 0.92 % divergence (5 nt substitutions and no indels) to N. antarctica CBS 7687T. A phylogenetic analysis employing the sequences of six genes (D1/D2 domain of large subunit rDNA, ITS, small subunit rDNA, two subunits of the RNA polymerase II and elongation factor-1α) indicated that the novel species belonged to the genus Naganishia and formed a well-supported clade with N. bhutanensis, N. antarctica and N. indica. Moreover, the two strains differed from their closest relatives by the ability to grow on distinct carbon and nitrogen sources and ability to grow at 30 °C. On the basis of these findings, we propose a novel species in the genus Naganishia (Filobasidiales), Naganishia floricola sp. nov. (holotype CGMCC 2.5856).
