“…Several yeast species (e.g., species of Spathaspora , Scheffersomyces , and Sugiyamaella clades) found in the guts and frass of wood‐boring insects were also found in their habitats, including rotting wood (Lopes et al, 2018a; Nguyen et al, 2006; Shi et al, 2021). Yeasts found in decomposing wood have been shown to often have the ability to assimilate and/or ferment lignocellulosic sugars, especially pentoses from the hemicellulosic fraction (Barros et al, 2020).…”

This study investigated the diversity of yeast species associated with rotting wood in Brazilian Amazonian rainforests. A total of 569 yeast strains were isolated from rotting wood samples collected in three Amazonian areas (Universidade Federal do Amazonas-Universidade Federal do Amazonas [UFAM], Piquiá, and Carú) in the municipality of Itacoatiara, Amazon state. The samples were cultured in yeast nitrogen base (YNB)-D-xylose, YNB-xylan, and sugarcane bagasse and corncob hemicellulosic hydrolysates (undiluted and diluted 1:2 and 1:5). Sugiyamaella was the most prevalent genus identified in this work, followed by Kazachstania.The most frequently isolated yeast species were Schwanniomyces polymorphus, Scheffersomyces amazonensis, and Wickerhamomyces sp., respectively. The alpha diversity analyses showed that the dryland forest of UFAM was the most diverse area, while the floodplain forest of Carú was the least. Additionally, the difference in diversity between UFAM and Carú was the highest among the comparisons. Thirty candidates for new yeast species were obtained, representing 36% of the species identified and totaling 101 isolates. Among them were species belonging to the clades Spathaspora, Scheffersomyces, and Sugiyamaella, which are recognized as genera with natural xylose-fermenting yeasts that are often studied for biotechnological and ecological purposes. The results of this work showed that rotting wood collected from the Amazonian rainforest is a tremendous source of diverse yeasts, including candidates for new species.

“…The internal transcribed spacer (ITS) regions and the D1/D2 domains of the large subunit (LSU) rRNA gene were amplified using the primer pairs ITS1/ITS4 ( White et al, 1990 ) and NL1/NL4 ( Kurtzman and Robnett, 1998 ), respectively. The PCR program was as follows: initial denaturation at 95°C for 3 min; 35 cycles of 94°C for 40 s, 56°C for 45 s, and 72°C for 1 min; and a final extension of 72°C for 10 min ( Shi et al, 2021 ). PCR products were cleaned and sequenced by Sangon Biotech Inc.…”

Phylogenetic and genomic analyses of two new species of Clavispora (Metschnikowiaceae, Saccharomycetales) from Central China

Species in the genus Clavispora have previously been reported primarily in the northeast and northwest regions of China; the species diversity of Clavispora in central China is not currently clear. In this study, phylogenetic inferences of Clavispora based on sequences of a single-locus (LSU D1/D2) and a two-locus (LSU D1/D2 and ITS) were conducted. Two new species isolated from rotting wood in central China, namely Clavispora xylosa sp. nov. and Clavispora paralusitaniae sp. nov., were delimited and proposed based on morphological and molecular evidence. Cl. xylosa was closely related to C. thailandica CBS 10610T, but with 11.5% divergence in the LSU D1/D2 domains and 11.5% divergence in the ITS regions. Cl. paralusitaniae was a sister to Cl. lusitaniae CBS 6936T from which it differs with 4.7% divergence in the LSU D1/D2 domains and 5.4% divergence in the ITS regions. Description of Cl. xylosa sp. nov. and Cl. paralusitaniae sp. nov. was also supported by morphological comparisons and genomic analyses between the two new species and their closest relatives, C. thailandica CBS 10610T and Cl. lusitaniae CBS 6936T. These results indicate a potentially great diversity of Clavispora spp. inhabiting rotting wood in central China, ripe for future discovery.

“…The Sugiyamaella genus has a worldwide distribution, and most of its species were originally found in Europe, North and South America and, more recently, in China. They were isolated either directly from wood-ingesting insects and insect frass, or from common insect habitats, such as rotting wood, forest soil, mushrooms, and peat [ 29 ]. In conclusion, it was shown that the analysis of samples with a prevailing (>60%) and atypical genus RA could help to infer the presumable impact of long-range transported air masses on the Ascomycota and Basidiomycota genera community structures, as found for the Streptophyta genera.…”

The atmosphere represents an underexplored temporary habitat for airborne microbial communities such as eukaryotes, whose taxonomic structure changes across different locations and/or regions as a function of both survival conditions and sources. A preliminary dataset on the seasonal dependence of the airborne eukaryotic community biodiversity, detected in PM10 samples collected from July 2018 to June 2019 at a coastal site representative of the Central Mediterranean, is provided in this study. Viridiplantae and Fungi were the most abundant eukaryotic kingdoms. Streptophyta was the prevailing Viridiplantae phylum, whilst Ascomycota and Basidiomycota were the prevailing Fungi phyla. Brassica and Panicum were the most abundant Streptophyta genera in winter and summer, respectively, whereas Olea was the most abundant genus in spring and autumn. With regards to Fungi, Botrytis and Colletotrichum were the most abundant Ascomycota genera, reaching the highest abundance in spring and summer, respectively, while Cryptococcus and Ustilago were the most abundant Basidiomycota genera, and reached the highest abundance in winter and spring, respectively. The genus community structure in the PM10 samples varied day-by-day, and mainly along with the seasons. The impact of long-range transported air masses on the same structure was also proven. Nevertheless, rather few genera were significantly correlated with meteorological parameters and PM10 mass concentrations. The PCoA plots and non-parametric Spearman’s rank-order correlation coefficients showed that the strongest correlations generally occurred between parameters reaching high abundances/values in the same season or PM10 sample. Moreover, the screening of potential pathogenic fungi allowed us to detect seven potential pathogenic genera in our PM10 samples. We also found that, with the exception of Panicum and Physcomitrella, all of the most abundant and pervasive identified Streptophyta genera could serve as potential sources of aeroallergens in the studied area.
