Abstract
Three yeast isolate candidates for a novel species were obtained from rotting wood samples collected in Brazil and Colombia. The Brazilian isolate differs from the Colombian isolates by one nucleotide substitution in each of the D1/D2 and small subunit (SSU) sequences. The internal transcribed spacer (ITS) and translation elongation factor 1-α gene sequences of the three isolates were identical. A phylogenetic analysis showed that this novel species belongs to the genus Ogataea. This novel species is phylogenetically related to Candida nanaspora and Candida nitratophila. The novel species differs from C. nanaspora by seven nucleotides and two indels, and by 17 nucleotides and four indels from C. nitratophila in the D1/D2 sequences. The ITS sequences of these three species differ by more than 30 nucleotides. Analyses of the sequences of the SSU and translation elongation factor 1-α gene also showed that these isolates represent a novel species of the genus Ogataea. Different from most Ogataea species, these isolates did not assimilate methanol as the sole carbon source. The name Ogataea nonmethanolica sp. nov. is proposed to accommodate these isolates. The holotype of Ogataea nonmethanolica is CBS 13485T. The MycoBank number is MB 851195.

Abstract
Four isolates of two novel ascosporogenous species belonging to the clade Starmera were obtained from cactus tissues and rotting wood in Brazil. Results of analyses of the sequences of the ITS and D1/D2 domains of the large subunit rRNA gene indicated that the two isolates of the cactophilic species are related to Starmera caribaea and Starmera pilosocereana, yeasts that are associated with cacti and require an organic source of sulfur for growth. We propose the novel species Starmera foglemanii sp. nov. (CBS 16113T; MycoBank number: MB 834400) to accommodate these isolates. The other two isolates are phylogenetically related to Candida dendrica, Candida laemsonensis and Candida berthetii, also in the Starmera clade. The novel species name Starmera ilhagrandensis sp. nov. (CBS 16316T; MycoBank number: MB 834402) is proposed for this species.

Abstract
Yeasts associated with rotting wood from four Atlantic Rain forest sites in Brazil were investigated using a culture medium based on sugarcane bagasse hydrolysate. A total of 330 yeast strains were isolated. Pichia manshurica, Candida pseudolambica, and Wickerhamomyces sp. 3 were the most frequently isolated species. Fourteen novel species were obtained in this study. All isolates were tested for their ability to ferment d-xylose and to produce xylanases. In the fermentation assays using d-xylose (30 g L-1), the main ethanol producers were Scheffersomyces stipitis (14.08 g L-1), Scheffersomyces sp. (7.94 g L-1) and Spathaspora boniae (7.16 g L-1). Sc. stipitis showed the highest ethanol yield (0.42 g g-1) and the highest productivity (0.39 g L-1h-1). The fermentation results using hemicellulosic hydrolysate showed that Sc. stipitis was the best ethanol producer, achieving a yield of 0.32 g g-1, while Sp. boniae and Scheffersomyces sp. were excellent xylitol producers. The best xylanase-producing yeasts at 50 °C belonged to the species Su. xylanicola (0.487 U mg-1) and Saitozyma podzolica (0.384 U mg-1). The results showed that rotting wood collected from the Atlantic Rainforest is a valuable source of yeasts able to grow in sugarcane bagasse hydrolysate, including species with promising biotechnological properties.

Abstract
BACKGROUND Opportunistic pathogenic yeast species are frequently associated with water
habitats that have pollution sources of human or animal origin.
Candida albicans has already been suggested as a faecal
indicator microorganism for aquatic environments. OBJECTIVES The goal of this study was to investigate the occurrence of C.
albicans and other opportunistic yeasts in sand and seawater
samples from beaches in Brazil to assess their correlation with
Escherichia coli, and to characterise the pathogenic
potential of the yeast isolates. METHODS Opportunistic species (yeasts that grow at 37ºC) were isolated from sand and
seawater samples from eight beaches in Brazil during the summer and the
winter. Opportunistic yeast species were evaluated for their susceptibility
to antifungal drugs, virulence factors, and the in vitro
and in vivo biofilm formation. Strains were selected to
carry out virulence tests using BALB/c mice. FINDINGS Several water samples could be classified as inappropriate for primary
contact recreation in relation to E. coli densities.
C. albicans was isolated in low densities. Of the 144
opportunistic yeasts evaluated, 61% displayed resistance or dose-dependent
sensitivity to at least one tested drug, and 40% produced proteinase.
Strains of C. albicans and Kodamaea ohmeri
exhibited the highest rates of adhesion to buccal epithelial cells. All the
C. albicans strains that were tested were able to
undergo morphogenesis and form a biofilm on catheter fragments in both
in vitro and in vivo experiments. It
was possible to confirm the pathogenic potential of three of these strains
during the disseminated infection test. MAIN CONCLUSIONS The identification of opportunistic yeast species in seawater and sand
samples from Brazilian beaches suggest a potential risk to the health of
people who use these environments for recreational purposes.

Abstract
We present the draft genome sequence of the type strain of the yeast Sugiyamaella xylanicola UFMG-CM-Y1884T (= UFMG-CA-32.1T = CBS 12683T), a xylan-degrading species capable of fermenting d-xylose to ethanol. The assembled genome has a size of ~ 13.7 Mb and a GC content of 33.8% and contains 5971 protein-coding genes. We identified 15 genes with significant similarity to the d-xylose reductase gene from several other fungal species. The draft genome assembled from whole-genome shotgun sequencing of the yeast Sugiyamaella xylanicola UFMG-CM-Y1884T (= UFMG-CA-32.1T = CBS 12683T) has been deposited at DDBJ/ENA/GenBank under the accession number MQSX00000000 under version MQSX01000000.

Abstract
Three novel D-xylose-fermenting yeast species of Spathaspora clade were recovered from rotting wood in regions of the Atlantic Rainforest ecosystem in Brazil. Differentiation of new species was 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 and 15 closely-related Debaryomycetaceae/Metschnikowiaceae species. Spathaspora girioi sp. nov. produced unconjugated asci with a single elongated ascospore with curved ends; ascospore formation was not observed for the other two species. The three novel species ferment D-xylose with different efficiencies. Spathaspora hagerdaliae sp. nov. and Sp. girioi sp. nov. showed xylose reductase (XR) activity strictly dependent on NADPH, whereas Sp. gorwiae sp. nov. had XR activity that used both NADH and NADPH as co-factors. The genes that encode enzymes involved in D-xylose metabolism (XR, xylitol dehydrogenase and xylulokinase) were also identified for these novel species. The type strains are Sp. girioi sp. nov. UFMG-CM-Y302(T) (=CBS 13476), Sp. hagerdaliae f.a., sp. nov. UFMG-CM-Y303(T) (=CBS 13475) and Sp. gorwiae f.a., sp. nov. UFMG-CM-Y312(T) (=CBS 13472).

Abstract
Three strains of a new xylanase-producing yeast species were isolated from rotting wood samples collected in the Atlantic Rain Forest of Brazil. The sequences of the internal transcribed spacer region and D1/D2 domains of the large subunit of the rRNA gene showed that this novel yeast species belongs to the genus Spencermartinsiella, and its closest relatives among recognized species are Spencermartinsiella europaea and Spencermartinsiella ligniputridi. A novel species, named Spencermartinsiella silvicola sp. nov., is proposed to accommodate these isolates. The type strain is UFMG-CM-Y274T ( = CBS 13490T). The MycoBank number is MB 813053. In addition, Candida cellulosicola is reassigned to the genus Spencermartinsiella as a new combination.

Abstract
Four strains of a novel yeast species were isolated from rotting-wood samples in an Atlantic rainforest site in the state of Minas Gerais, Brazil. These yeasts were obtained from enrichments using yeast nitrogen base (YNB)-d-xylose or YNB-xylan media. The novel yeast species produces bacilliform ascospores typical of the genus Sugiyamaella, and its closest described relative in terms of sequence similarity is Candida (iter. nom. Sugiyamaella) marionensis. The yeast is able to grow in medium with xylan as sole carbon source and produces extracellular enzymes with xylanolytic activities. The novel species Sugiyamaella xylanicola sp. nov. is proposed to accommodate these isolates. The type strain is UFMG-CA-32.1(T) (=CBS 12683(T) =CBMAI 1467(T)).

Abstract
Two novel yeast species were isolated from nectar of flower bracts of Heliconia psittacorum (Heliconiaceae) collected in a Cerrado ecosystem in the state of Tocantins, northern Brazil. Wickerhamiella pagnoccae sp. nov., which is closely related to Candida jalapaonensis, is heterothallic and produces one spheroid ascospore per ascus. Candida tocantinsensis sp. nov. belongs to the Metschnikowiaceae clade and its nearest relative is Candida ubatubensis, but the sequence identity (%) in the D1/D2 domains of the rRNA gene is low. The type strain of W. pagnoccae is UFMG-F18C1T ( = CBS 12178T = NRRL Y-48735T) and the type strain of C. tocantinsensis is UFMG-F16D1T ( = CBS 12177T = NRRL Y-48734T).

Abstract
This study compared the effect of using two different concentrations of sodium hydroxide (NaOH) in the N-acetyl-L-cysteine-sodium hydroxide (NALC-NaOH) method for sputum decontamination on smear and culture positivity and the proportion of contaminated cultures: 14% of cultures were contaminated using the standard final 1% NaOH concentration during processing compared to 11% contaminated cultures using a final 1.25% NaOH concentration (P < 0.008). The proportion of cultures positive for mycobacteria decreased from 21% to 11% for sputum processed with 1% and 1.25% final NaOH concentrations, respectively (P < 0.001). Our findings suggest that a small reduction in culture contamination did not justify the considerable loss of positive cultures.
