Summary: Polyphasic analysis was conducted on six isolates recovered from two different environments in Jeju, Republic of Korea, revealing them to belong to the genus Rahnella, with two strains representing new species within the genus. The isolates exhibited similarities in 16S rRNA gene sequences and unique physiological and chemotaxonomic characteristics, leading to the proposal of Rahnella laticis sp. nov. and Rahnella contaminans sp. nov. for two novel species. An updated description of the genus Rahnella was also provided based on the results of this study.

Summary: Ten acidophilic bacteria strains, which form a monophyletic clade within Firmicutes, were isolated from different environments. Comparison of their complete genomes revealed two proposed genera (Sulfoacidibacillus and Ferroacidibacillus) and three proposed species (Sulfoacidibacillus ferrooxidans, Sulfoacidibacillus thermotolerans, and Ferroacidibacillus organovorans). These bacteria strains share physiological traits such as iron oxidation and reduction, as well as being obligately heterotrophic. Additionally, they exhibit different degrees of acid tolerance and temperature preferences. The importance of these findings is rated as 8 out of 10.

Summary: The metagenome of fouling from a sulfidic spring in Russia was sequenced, and the dominant microbial community consisted of members of the phyla Gammaproteobacteria, Cyanobacteria, and Campilobacteriota. The complete genomes of two Thiothrix species, Thiothrix sulfatifontis and Thiothrix winogradskyi, were assembled and their taxonomic status was determined. The study also observed the anaerobic growth of Thiothrix in the presence of thiosulfate for the first time.

Summary: A new actinobacterium, Occultella aeris gen. nov., sp. nov., was isolated from surface soils of ancient copper mines and smelters in East Harz, Germany, exhibiting unique growth characteristics and chemical composition. The strain is closely related to the genera Ruania and Haloactinobacterium, leading to proposed reclassification and renaming within the family Ruaniaceae. The genomic and chemotaxonomic analyses support the establishment of Occultella aeris gen. nov., sp. nov. as a distinct genus and species.

Summary: A novel micro-organism named Salsipaludibacter albus was isolated from dry salt in Portugal. It is a Gram-stain-positive, rod-shaped bacterium that requires oxygen for growth. The strain exhibits pleomorphism, with long filaments of rod-shaped cells and coccoid cellular forms at the end of the filaments. It grows best at temperatures between 20-30 degrees C, NaCl concentrations of 2%, and pH values of 8.0-11.0. Based on genomic, phylogenetic, phenotypic, and chemotaxonomic studies, it is proposed that Salsipaludibacter albus represents a new genus, species, family, and order.

Summary: Hermetia illucens larvae, also known as black soldier fly larvae (BSFL), are efficient in converting organic waste into high-quality biomass. This study explored the role of gut microbes in this process by culturing members of the core gut microbiota. Two cultivation strategies were employed, dilution-to-extinction cultivation and direct plating, resulting in the isolation of a diverse range of bacterial strains. Phylogenetic analysis identified predominant genera, such as Providencia, Proteus, Morganella, Enterococcus, Bacillus, and members of the family Enterobacteriaceae, which have been previously associated with the BSFL gut microbiota. Genomic fingerprinting provided insights into the genetic diversity of the cultured bacteria that could not be obtained solely through 16S rRNA gene sequencing.

Summary: Integrating genomic information into microbial systematics allows for reliable prokaryotic classification. In silico chemotaxonomic analysis is being introduced to replace traditional laboratory methods for characterizing taxa, increasing speed and accuracy of taxonomic reports. Genomics has already played a role in taxonomic rearrangement, highlighting the need for revisiting taxonomy in light of new genomic data.
