Summary: A novel aerobic, Gram-staining-negative, non-motile, short-rod-shaped strain, named Orrella daihaiensis sp. nov., was isolated from Daihai Lake in Inner Mongolia, China. The strain showed high similarity to Orrella marina based on 16S rRNA gene sequences analysis. It exhibited specific growth characteristics and cellular structures under certain conditions of light, temperature, and salinity. The polyphasic analysis confirmed that the strain represents a new species within the genus Orrella.

Summary: A novel chemolithoautotrophic bacterium strain H1576(T) was isolated from water of a brackish lake. The bacterium can grow aerobically on inorganic sulfur compounds and does not rely on hydrogen gas for autotrophic growth. Phylogenetic analysis revealed that strain H1576(T) belongs to the genus Sulfurimonas but is distinct from existing species. Therefore, a new species named Sulfurimonas aquatica sp. nov. is proposed.

Summary: The study utilized a protein-encoding gene to reveal hidden ecological patterns within a single operational taxonomic unit, leading to the detection of 600 species-like taxa in 99 freshwater habitats. It showed how environmental conditions shape bacterial communities and identified a surprising compositional separation of Polynucleobacter communities in habitats with different levels of calcium ions. This new approach opens up a window to explore the incredible diversity of free-living bacteria and investigate the impact of environmental conditions on bacterial evolution.

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.
