During a survey of yeasts associated with insects in Central China's natural ecosystems, 116 yeast strains were isolated from the gut of adult insects in two families and from one beetle larva. Among the yeasts isolated in this study, 102 strains were identified as 20 known species in the class Saccharomycetes. The remaining 14 strains were identified as representing five novel species in the Lodderomyces clade based on the combined sequences of the D1/D2 domains of the LSU rRNA gene and the internal transcribed spacer (ITS) regions, as well as other taxonomic characteristics. Lodderomyces beijingensis sp. nov. (type strain CBS 14171T=CICC 33087T=NYNU 15764T) formed a clade with Lodderomyces elongisporus and Candida oxycetoniae. The other four novel species, namely Candida margitis sp. nov. (type strain CBS 14175T=CICC 33091T=NYNU 15857T), Candida xiaguanensis sp. nov. (type strain CBS 13923T=CICC 33056T=NYNU 1488T), Candida parachauliodis sp. nov. (type strain CBS 13928T=CICC 33058T=NYNU 14959T) and Candida coleopterorum sp. nov. (type strain CBS 14180T=CICC 33084T=NYNU 1582T), showed close relationships to the species near Candida parapsilosis, Candida sakaeoensis, Candida chauliodes and Candida corydalis. Descriptions of these novel yeast species are provided as well as discussions of their ecology in relation to their insect hosts.

A bacterial strain P1, capable of degrading diesel and converting thiosulfate to sulfate was isolated from an oil-contaminated soil sample. The cells were Gram-stain-negative, slightly curved rods and motile with a single polar flagellum. Growth of the strain was observed at 4-45 °C (optimum at 28 °C), at pH 4.

Introduction: Allergic fungal rhinosinusitis (AFRS) is a distinct subset of chronic rhinosinusitis characterized by a type I hypersensitivity to fungi. Immunocompromised patients are at increased risk for fungal infections. This case highlights the complexities of managing AFRS in patients not eligible for surgery.

The spatial transcriptomics is a rapidly evolving biological technology that simultaneously measures the gene expression profiles and the spatial locations of spots. With progressive advances, current spatial transcriptomic techniques can achieve the cellular or even the subcellular resolution, making it possible to explore the fine-grained spatial pattern of cell types within one tissue section. However, most existing cell spatial clustering methods require a correct specification of the cell type number, which is hard to determine in the practical exploratory data analysis.

A novel yeast species, isolated from the bark of pine trees in Gyeongju, South Korea, and designated as KCTC 37304 (ex-type KACC 410729), is characterized by its genetic, morphological and physiological properties. Molecular phylogenetic analysis involving the D1/D2 domain of the 26S LSU rRNA gene and the internal transcribed spacer (ITS) region confirms that it belongs to the genus . In comparison to CBS:10065, the type strain of its closest relative, KCTC 37304 exhibits 8 nucleotide substitutions (~2.

Six strains (DMKU-SG26, DMKU-SG42, DMKU-SYM22, DMKU-RG41, DMKU-RX317 and DMKU-RGM25) representing a novel basidiomycetous yeast species were isolated from leaf surfaces of mangrove plants collected in Thailand. Pairwise sequence analysis indicated that the six strains either had identical nucleotide substitution in the D1/D2 domains of the large subunit (LSU) rRNA gene sequences or differed by one to three nucleotide(s). They also had identical or differed by one to five nucleotide substitution(s) in the internal transcribed spacer (ITS) regions.
