Comparative genomics of biotechnologically important yeasts
TLDR
The comparative genome analysis of 29 taxonomically and biotechnologically important yeasts, including 16 newly sequenced, enables correlation of genes to useful metabolic properties and showed the synteny of the mating-type locus to be conserved over a billion years of evolution.
Physiological characterization of thermotolerant yeast for cellulosic ethanol production
TLDR
The study shows that S. cerevisiae industrial strains have the potential to produce cellulosic ethanol once ethanol had presented yields similar to yields from thermotolerant strains, and although the K. marxianus strains have fermentative capacities similar to strains of S. Cerevisiae, they have low tolerance to ethanol.
d-Xylose fermentation, xylitol production and xylanase activities by seven new species of Sugiyamaella
TLDR
Sixteen yeast isolates identified as belonging to the genus Sugiyamaella were studied in relation to D-xylose fermentation, xylitol production, and xylanase activities, suggesting that seven new species have good potential for biotechnological applications.
Yeasts Associated with Decomposing Plant Material and Rotting Wood
TLDR
The physiological characteristics that allowed these yeasts to adapt to decaying plant substrates make these organisms interesting for biotechnological applications.
Genomic analysis and D-xylose fermentation of three novel Spathaspora species: Spathaspora girioi sp. nov., Spathaspora hagerdaliae f. a., sp. nov. and Spathaspora gorwiae f. a., sp. nov.
TLDR
Three novel D-xylose-fermenting yeast species of Spathaspora clade were recovered from rotting wood in regions of the Atlantic Rainforest ecosystem in Brazil based on analyses of the gene encoding the D1/D2 sequences of large subunit of rRNA and on 642 conserved, single-copy, orthologous genes from genome sequence assemblies from the newly described species.
Yamadazyma riverae sp. nov., a yeast species isolated from plant materials.
TLDR
Nine strains of a novel yeast species were isolated from rotting wood, tree bark, ant nests or living as endophytes in leaves of Vellozia gigantea and showed that this species was related to Candida insectorum in the Yamadazyma clade.
Scheffersomyces stambukii f.a., sp. nov., a d-xylose-fermenting species isolated from rotting wood.
TLDR
Analysis of the sequences of the D1/D2 domains showed that this new species is phylogenetically related to Scheffersomyces NYMU 15730, a species without a formal description, and the two are in an early emerging position with respect to the xylose-fermenting subclade containing Schefferomyces titanus and Scheffesomyces stipitis.
Kurtzmaniella hittingeri f.a., sp. nov., isolated from rotting wood and fruits, and transfer of three Candida species to the genus Kurtzmaniella as new combinations.
TLDR
Analysis of the sequences of the internal transcribed spacer region and the D1/D2 domains of the large subunit rRNA gene showed that the novel species belongs to the Kurtzmaniella clade, which differs from its closest relative, Candida natalensis.
