Summary: Thirteen Gram-positive, catalase-positive, rod-shaped colonies were isolated from a strawberry leaf and found to be closely related to each other based on gene sequence similarities. Two of the isolates (AMBP162T and AMBP252) were whole-genome sequenced and showed no distinguishable differences. Compared to reference genomes, the AMBP162T genome was most similar to Latilactobacillus curvatus, indicating a novel species. Based on genotypic and phenotypic data, a new Latilactobacillus species, Latilactobacillus fragifolii sp. nov., is proposed.

Summary: Two strains HN-1(T) and 39 isolated from different plant rhizospheres in China were found to have high nitrogenase activities and nearly identical 16S rRNA gene sequences, indicating they belong to the same species. They were identified as a novel species of the genus Paenibacillus, named Paenibacillus sinensis, based on distinct phenotypic and genomic characteristics, despite their close relationship to Paenibacillus stellifer.

Summary: Two strains of Actinobacteria, CRXT-Y-14(T) and CRXT-G-22(T), isolated from healthy leaves and seeds of Xanthium sibiricum, display characteristic morphological features consistent with the Streptomyces genus. Phylogenetic analyses suggest CRXT-Y-14(T) may represent a novel species, while CRXT-G-22(T) is closely related to Streptomyces acidiscabies. Proper classification as Streptomyces xanthii and Streptomyces roseirectus is proposed based on genetic and phenotypic characteristics.

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: In this study, the authors developed an improved method for the identification of Aspergillus species using MALDI-TOF MS. By cultivating the fungi on a polycarbonate filter, they were able to obtain reliable mass spectra and achieve higher accuracy in species identification compared to the recommended liquid cultivation method. This method showed promise for the identification of other filamentous fungi as well.

Summary: In the era of increasingly complex consumer lifestyles, the conventional baker's yeast is facing some issues, prompting the need to search for alternative yeasts. Through evolutionary engineering, potential alternative baker's yeasts were identified and their baking traits were improved. The evolved yeasts showed improved ability to withstand baking associated stresses and produced bread with higher loaf volume.

Summary: Candida parapsilosis is a common cause of candidemia in certain geographical areas and among children. However, the proportion of cases varies among children in different regions. This study found no evidence of clonal outbreaks in the pediatric ward in Iran, but highlighted the importance of using appropriate discriminatory methods for outbreak investigation.

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.
