Summary: A new yeast species belonging to the basidiomycetous yeast genus Cystofilobasidium was isolated from a marine sediment sample in Shandong province, China. Phylogenetic analysis based on gene sequences showed that this strain represents a novel species, named Cystofilobasidium josepaulonis sp. nov. This species differs from known species in the genus in terms of DNA sequence mismatches and teliospore germination behavior.

Summary: Through yeast isolation and meta-barcoding analysis, we found that there are various basidiomycetous yeasts, not just Microsporomyces species, associated with Cladonia rei lichen in Japan. The most frequently detected species belong to the Septobasidium genus, which is associated with scale insects, and Halobasidium xiangyangense is a potential generalist epiphytic fungus that can associate with C. rei lichen.

Summary: Gram-negative strains NS12-5T and RP8T were isolated from rice rhizosphere soil and fermented fruits of Liriope platyphylla in Korea, respectively. Phylogenetic analysis showed that NS12-5T was closely related to Ideonella aquatica 4Y11T, while RP8T was closely related to Spirosoma aureum BT328T. Based on phenotypic, genomic, and phylogenetic characteristics, NS12-5T and RP8T represent novel species in the genus Ideonella and Spirosoma, respectively, and are proposed as Ideonella oryzae sp. nov. and Spirosoma liriopis sp. nov.

Summary: Five novel halophilic archaeal strains were isolated from coastal saline sediments and sea salt in China. They demonstrated typical morphology and growth characteristics and showed high similarities with existing species. However, based on genetic and phylogenetic analyses, it is confirmed that these strains represent five new species. This is the first report of a novel haloarchaeon isolated from a marine intertidal zone.

Summary: Yeast, defined as unicellular fungi, are found in various fungal lineages and are not a taxonomic unit; it may take hundreds of years to fully document all yeast species. Many areas, including cold habitats and threatened environments, remain unsampled for yeasts. Studies have shown hybrid yeast species, prevalent yeast communities in natural habitats impacted by deforestation, and surprising global distributions of yeast species in soils and marine waters.

Summary: Malassezia furfur is a common commensal member of human/animal microbiota that is also associated with several pathogenic states. Recent studies report the involvement of Malassezia species in Crohn's disease, pancreatic cancer, and cystic fibrosis. A recent genomics analysis revealed the existence of hybrid isolates and identified their putative parental lineages, showing the occurrence of multiple hybridization events in the species' evolutionary trajectory.

Summary: Irritable bowel syndrome (IBS) is a common disorder characterized by chronic abdominal pain and changes in bowel movements. Visceral hypersensitivity may be caused by intestinal fungi, but the diversity of fungal communities does not differ between IBS subgroups. The study highlights the importance of conducting strain-specific cause-and-effect studies in IBS research.

Summary: Aspergillus species are the leading cause of invasive aspergillosis in immunocompromised hosts, and their susceptibility to antifungal agents might vary. This study aimed to investigate the frequency of Aspergillus species among Iranian patients and their susceptibility to seven antifungals. The results showed that Aspergillus section Flavi species were the most common and that luliconazole, caspofungin, and isavuconazole were the most effective antifungal agents for treating Aspergillus infections.

Summary: The study reveals the mechanism of self-compatibility in the fungal species Cryptococcus depauperatus, which is closely related to human fungal pathogens. Through comparative genomics and analysis of mutants, the researchers demonstrate that the sexual cycle of C. depauperatus involves meiosis and is orchestrated by a mating receptor and pheromone ligand pair. These findings provide insights into transitions between sexual reproduction modes in the fungal kingdom.

Summary: A new species of the yeast genus Blastobotrys was discovered in house dust, with similar species detected globally in various substrates. The new species, Blastobotrys davincii, was classified based on morphological, phylogenetic, and physiological characters. The preferred name for the new species is still under debate, but Blastobotrys is argued to be more suitable than Trichomonascus. A nomenclatural review and accepted species list for Blastobotrys/Trichomonascus clade were also provided.

Summary: The purpose of this study was to optimize fermentation parameters to create favorable conditions for bioethanol production from sugar-rich substrates. The response surface method based on central composite design was used to determine the optimal conditions. The results confirmed the feasibility of achieving high ethanol yield using these conditions. The study demonstrated that the response surface method with central composite design is an effective approach for bioethanol production from molasses.
