<i>Gracilimonas qinghaiensis</i> sp. nov., a halophilic bacterium from a high-altitude saline lake exhibiting diverse metabolic potential and ecological adaptation.

ABSTRACT: Saline lakes are extreme habitats that host unique microbial communities with high biotechnological potential. In this study, a novel strain, designated Q87^T, was isolated from Gaxiukule Lake, a high-altitude magnesium sulfate-type saline lake in the Qaidam Basin, China. A polyphasic taxonomic approach, including morphological, physiological, chemotaxonomic, phylogenetic, and genomic analyses, was applied to characterize the isolate. Strain Q87^T is a Gram-stain-negative, non-motile, rod-shaped bacterium showing high tolerance to salinity (0-15.0 %, w/v; optimum 5.0 %) and alkalinity (pH 6.0-10.5; optimum pH 7.0), with a temperature range for growth of 10-40 °C (optimum 32 °C). Phylogenetic and genomic analyses confirmed its affiliation with the genus Gracilimonas</
