Summary: During previous research, strain NEAU-J3T was classified as a new genus called 'Wangella', but unfortunately, the name was not accepted. In this study, a new genus called 'symbolscript' is described, and a polyphasic approach was used to support the classification. The genomic DNA of the type strain has a G+C content of 71.6%. Digital DNA-DNA hybridization and average nucleotide identity (ANI) were used to differentiate NEAU-J3T from related strains. Phenotypic, genetic, and chemotaxonomic data indicate that NEAU-J3T is distinct from known genera in the family 'symbolscript'. Therefore, NEAU-J3T represents a novel species of a novel genus, and the proposed name is 'symbolscript symbolscript gen. nov., sp. nov.'.

Summary: Two novel anaerobic strains, designated AF52-21(T) and CM04-06(T), were isolated from faeces of healthy Chinese donors using a pure culture strategy. Phylogenetic analysis revealed that these strains clustered with Faecalibacterium species, supporting their recognition as two new species within the genus. Genomic analysis showed differences below the proposed species threshold, confirming their uniqueness.

Summary: Two new species of Chlamydomonas-like algae, found in Swedish, English, and Norwegian waters, are described. These species have distinct morphological characteristics, and genetic analysis has led to their reclassification into a new genus Limnomonas. The study highlights the differences between the two species and confirms their sexual incompatibility.

Summary: Four novel strains of Myxobacteria were isolated from soil samples in Guangdong province and Qinghai province, China. Phylogenetic analysis and genomic sequencing revealed that these strains belong to the genera Myxococcus and Pyxidicoccus. Comparative genomics analysis showed extensive genetic diversity in the Myxococcus and Pyxidicoccus genera.

Summary: Five strains belonging to the genus Fructobacillus were isolated from paper mulberry in Taiwan. Phylogenetic analysis based on gene sequences showed that these strains represented four novel species. The proposed names for these species are Fructobacillus papyriferae sp. nov., Fructobacillus papyrifericola sp. nov., Fructobacillus broussonetiae sp. nov., and Fructobacillus parabroussonetiae sp. nov.

Summary: Investigation of various cheese rinds for Bisifusarium domesticum revealed unexpected diversity of Fusarium-like fungi, leading to the discovery of four novel cheese-associated species, including two new genera. A multi-gene phylogenetic analysis, morphological observations, and metabolite profiling were used to determine the phylogenetic position and characteristics of the isolates.

Summary: This study reports the discovery of epibiotic species associated with Neocaridina davidi shrimp collected from the wild, aquaculture ponds, and aquaria. Among 900 imported shrimp from Taiwan, three-quarters of them host at least one of the recorded epibionts. Two new species, Cladogonium kumaki sp. nov. and Monodiscus kumaki sp. nov., were found, along with the redescriptions of Holtodrilus truncatus and Scutariella japonica. The highest number of epibionts is found in shrimp from aquaculture ponds, while the lowest is found in individuals from aquaria. The occurrence of epibionts differs across designated microhabitats. Their presence may affect shrimp breeding rates, thus requiring more control measures.

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: Polyphasic taxonomic studies were conducted on seven strains isolated from sap extracted from Acer pictum in Mt. Halla in Jeju, Republic of Korea, leading to the proposal of a new species, Rouxiella aceris, within the genus Rouxiella. The strains exhibited distinct sublines within the family Yersiniaceae based on 16S rRNA gene phylogeny and core gene analysis.

Summary: Three novel species of the genus Microbacterium have been identified as potential producers of C50 carotenoids, with low sequence identity and physiological differences from closely related species. These strains exhibit unique isoprenoid biosynthetic pathways and further investigation of their genomes is warranted.

Summary: The study proposed a new classification for the Geobacterales order, suggesting new genera and species, and described two novel isolated soil bacteria strains. By using phylogenomic analysis and genomic comparisons, the boundaries for different genera were established, and new genera and species were proposed based on the results.

Summary: This study analyzed the phylogeny, ecology, and biogeography of the "marine Geitlerinema" cluster representatives and identified two subclusters with distinct distributions. The ecological and geographical diversity of the Sodalinema genus was expanded, leading to the proposal of three new species. Additionally, a new genus and species, Baaleninema simplex gen. et sp. nov., were described within the PCC7105 Glade, contributing to the clarification of the confusion surrounding the "marine Geitlerinema" group.
