Significance The highly diverse Ascomycete yeasts have enormous biotechnological potential. Collectively, these convert a broad range of substrates into useful compounds, such as ethanol, lipids, and vitamins, can grow in extremes temperature, salinity, pH. We compared 29 yeast genomes with the goal correlating genetics to traits. In one rare species, we discovered genetic code that translates CUG codons alanine rather than canonical leucine. Genome comparison enabled correlation genes...
Organisms exhibit extensive variation in ecological niche breadth, from very narrow (specialists) to broad (generalists). Two general paradigms have been proposed explain this variation: (i) trade-offs between performance efficiency and breadth (ii) the joint influence of extrinsic (environmental) intrinsic (genomic) factors. We assembled genomic, metabolic, data nearly all known species ancient fungal subphylum Saccharomycotina (1154 yeast strains 1051 species), grown 24 different...
Deschampsia antarctica Desv. (Poaceae) represents one of the two vascular plants that have colonized Antarctic continent, which is usually exposed to extreme environmental conditions. In this work, we characterized endophytic fungi associated with leaves D. antarctica. Endophytic were recovered from 91 individual different points Admiralty Bay at King George Island, Antarctica. A total 26 fungal isolates obtained 273 leaf fragments. All identified by analysis sequences internal transcribed...
The yeast communities associated with the stingless bees Tetragonisca angustula, Melipona quadrifasciata and Frieseomelitta varia were studied. T. angustula F. showed a strong association Starmerella meliponinorum. M. more frequently carried species related to Candida apicola, but also vectored low numbers of S. Some yeasts isolated from adult typical known occur in flowers. Other found those phylloplane. meliponinorum C. apicola complex, part clade, may have mutualistic relationship Many...
Heavy usage of gasoline, burgeoning fuel prices, and environmental issues have paved the way for exploration cellulosic ethanol. Cellulosic ethanol production technologies are emerging require continued technological advancements. One most challenging is pretreatment lignocellulosic biomass desired sugars yields after enzymatic hydrolysis. We hypothesized that consecutive dilute sulfuric acid-dilute sodium hydroxide would overcome native recalcitrance sugarcane bagasse (SB) by enhancing...
Fatty acid methyl esters (FAMEs) were obtained from vegetable oils of soybean, corn and sunflower. The current study was focused on evaluating the antifungal activity FAMEs mainly against Paracoccidioides spp., as well testing interaction these compounds with commercial drugs also their antioxidant potential. presented small IC50 values (1.86-9.42 μg/mL). All three tested showed isolates spp. MIC ranging 15.6-500 µg/mL. Sunflower exhibited that extended to other genera, an 15.6 μg/mL Candida...
The diversity of yeasts collected from different sites in Antarctica (Admiralty Bay, King George Island and Port Foster Bay Deception Island) their ability to produce extracellular enzymes mycosporines were studied. Samples during the austral summer season, between November 2006 January 2007, rhizosphere Deschampsia antarctica, ornithogenic (penguin guano) soil, marine lake sediments, water freshwater lakes. A total 89 isolates belonging following genera recovered: Bensingtonia, Candida,...
Background Independent surveys across the globe led to proposal of a new basidiomycetous yeast genus within Bulleromyces clade Tremellales, Bandoniozyma gen. nov., with seven species. Methodology/Principal Findings The species were characterized by multiple methods, including analysis D1/D2 and ITS nucleotide sequences, morphological physiological/biochemical traits. Most can ferment glucose, which is an unusual trait among yeasts. Conclusions/Significance In this study we propose...
This work describes the distribution and diversity of fungal endophytes associated with leaves Colobanthus quitensis, a dicotyledonous plant that lives in Antarctica. A total 188 isolates were obtained from six different sites located across 25.5-km transect through Admiralty Bay, at King George Island. The ITS1-5.8S-ITS2 nuclear ribosomal gene was sequenced endophytic fungi identified as species belonging to genera Aspergillus, Cadophora, Davidiella, Entrophospora, Fusarium, Geomyces,...
Background This study is the first to investigate Brazilian Amazonian Forest identify new D-xylose-fermenting yeasts that might potentially be used in production of ethanol from sugarcane bagasse hemicellulosic hydrolysates. Methodology/Principal Findings A total 224 yeast strains were isolated rotting wood samples collected two forest reserve sites. These cultured nitrogen base (YNB)-D-xylose or YNB-xylan media. Candida tropicalis, Asterotremella humicola, boidinii and Debaryomyces hansenii...

This study assessed the diversity and distribution of filamentous fungi obtained from water sampled six lakes in Antarctic Peninsula. One hundred twenty-eight fungal isolates were purified identified by analysis nuclear rDNA ITS region sequences as belonging to 31 different operational taxonomic units (OTUs). The most frequently isolated Geomyces pannorum Mortierella sp.; these species occurred three sampled, respectively, displayed highest total colony-forming unit per L. Different that...
The production of ethanol and other fuels chemicals from lignocellulosic materials is dependent efficient xylose conversion. Xylose fermentation capacity in yeasts usually linked to reductase (XR) accepting NADH as cofactor. XR Scheffersomyces stipitis, which able use cofactor but still prefers NADPH, has been used generate recombinant xylose-fermenting Saccharomyces cerevisiae. Novel species, those the Spathaspora clade, have described are potential sources novel genes improve S. by six...
