AI Article Synopsis
- A new species of anamorphic ascomycetous yeast was identified from soil and mushroom samples in Taiwan, with four distinct strains isolated between 2006 and 2007.
- Genetic analysis revealed minor nucleotide differences among the strains, indicating they are closely related but distinct from other species, with noticeable divergences in rRNA and internal transcribed spacer sequences.
- The study concludes by naming the new species, providing the classification details, and noting that these strains show unique carbon and nitrogen assimilation patterns—suggesting they do not reproduce sexually.
Article Abstract
This study describes , a new anamorphic ascomycetous yeast species, four strains of which were isolated from soil and the fruiting body of a mushroom in Taiwan between 2006 and 2007. Analysis of the sequences of the large-subunit rRNA, small-subunit rRNA and elongation factor-1α identified this species as a member of the clade. The yeast strains of exhibited a 0-3 nucleotide difference in the sequences of the D1/D2 domain of the large subunit rRNA when compared to one another and a 10 and 11 nucleotide difference when compared to sp. BG99-11-14-10-4-1 and NRRL Y-7574, the closest undescribed species, respectively. The yeast strains differed by 77 and 78 nucleotides from s and , the close species, respectively. The internal transcribed spacer sequences of the four isolates exhibited a divergence of 106-108 substitutions from the recognized species . No sexual reproduction was observed. The strains differed from those of related species in terms of their carbon and nitrogen assimilation patterns. Therefore, this study proposes f.a., sp. nov. to accommodate these four strains, with BCRC 23185 (isotype CBS 11432; MycoBank number MB563484) as the holotype.

Aim: This study aimed to assess if the addition of origanum oil to denture materials could decrease microorganisms counts and biofilm formation without changing their mechanical/surface properties.
Materials And Methods: A total of 66 resilient denture liner discs (SoftConfort, Dencril Comércio de Plásticos Ltda, SP, Brazil) were prepared with fixed dimensions of 10 × 3 mm for biofilm assay ( = 36) and 12 × 2 mm for sorption-solubility tests ( = 30) containing three oil concentrations - 0, 2.5 and 5%, thereby = 12 per each group samples for biofilm assay and = 10 per each group for sorption-solubility test respectively.

Infections of intact and damaged skin barriers and keratin are frequently associated with complex biofilm communities containing bacteria and fungi, yet there are limited options for successful management. This study intended to focus on the utility of some novel proprietary lactam molecules, quorum sensing (QS)-derived halogenated furanones, which act to block the QS pathway, against key fungal pathogens of the skin (Candida albicans, Malassezia furfur and Microsporum gypseum). Moreover, we aimed to assess how these actives performed against complex interkingdom biofilms in a clinically relevant model.

Serine-arginine protein kinases (SRPKs) play important roles in diverse biological processes such as alternative splicing and cell cycle. However, the functions of SRPKs in DNA damage response remain unclear. Here we characterized the function of SRPKs homolog Dsk1 in regulating DNA repair in the fission yeast Schizosaccharomyces pombe.
