Summary: This study presents two strains affiliated with the GKS98 cluster. Phylogenetic analysis suggests that these strains are closely related to the family Alcaligenaceae and previously described species Orrella amnicola and Orrella marina. Based on the phylogenomic trees and other characteristics, the authors propose the establishment of new genera Zwartia gen. nov. and Jezberella gen. nov., and the reclassification of Orrella amnicola into the new genus Sheuella gen. nov.

Summary: A lemon-chiffon strain named Parachryseolinea silvisoli sp. nov. was isolated from a soil sample collected from Qinghai Virgin Forests, Qinghai Province, PR China. This strain belongs to the family Fulvivirgaceae and represents a new species in a new genus. Additionally, the reclassification of Chryseolinea flava as Pseudochryseolinea flava gen. nov., comb. nov. is proposed.

Summary: Two new bacterial strains, Marseille-P2698(T) and Marseille-P2260(T), were isolated from human stools using the culturomic method. These two strains were fully described using the taxonogenomic approach. Marseille-P2698(T) was identified as a Gram-negative, motile, non-spore-forming, rod-shaped bacterium, while Marseille-P2260(T) was identified as a Gram-positive, motile, spore-forming rod-shaped bacterium.

Summary: The genus Nostoc contributes significantly to carbon and nitrogen availability in terrestrial ecosystems and forms symbiotic relationships with non-diazotrophic organisms. A study identified new Nostoc-like cyanobacterial genera and species in South American ecosystems, highlighting the importance of these regions for harboring unknown microbial diversity in the face of increasing anthropogenic threats.

Summary: A novel Gram-stain-positive coccus-shaped bacterium, designated as INB8(T), was isolated from hypersaline marine water sample collected at the Inland Sea of Qatar. Phylogenetic analysis indicated that the strain belongs to a new species within the genus Ruoffia. It is proposed to reclassify several other Facklamia species based on genetic and phenotypic information.

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: Examination of fungal specimens collected in the Atlantic rain forest ecosystems of Northeast Brazil revealed many potentially new species of Glomeromycota, with two closely related fungi forming glomerocarps. Phylogenetic analyses indicated that these two fungi represent two divergent undescribed species in the family Glomeraceae, with one placed in the genus Dominikia and the other in a sister clade to the genus Kamienskia.

Summary: The genus Clostridium is diverse and includes species like C. cocleatum, C. ramosum, C. spiroforme, and C. saccharogumia. These species form a distinct cluster within the family Coprobacillaceae in the order Erysipelotrichales. Based on phylogenetic, genomic, phenotypic, and chemotaxonomic information, it is proposed that these species be transferred to a new genus called Thomasclavelia.

Summary: The study isolated four Prolixibacter strains, belonging to the Bacteroidetes phylum, that were able to reduce nitrate under anaerobic conditions, leading to enhanced corrosion of Fe-0 and carbon steel. The corrosion was mainly attributed to biological reduction of nitrate to nitrite followed by chemical oxidation of Fe-0 to Fe2+ and Fe3+.

Summary: In this study, the de novo synthesis of triacylglycerol (TAG) in Coccomyxa sp. Obi strain under nitrogen (N)-replete and N-limiting conditions was analyzed. The results showed that TAG synthesis is limited by fatty acid supply under N-replete conditions, while it is enhanced under N-limiting conditions. The expression of the acyl-ACP thioesterase, FAT1, involved in releasing fatty acids from acyl-ACP, was induced under N-limiting conditions. Furthermore, the turnover of TAG was significant under N-replete conditions. The slow conversion of diacylglycerol to TAG partly explained the slower rate of TAG synthesis compared to polar lipid synthesis under N-limiting conditions.
