Dataset of Differences in nirS-Type Denitrifying Microbial Communities and Their Environmental Drivers in Sediments of Saline Lakes on the Qinghai–Tibetan Plateau

This dataset covers all experimental data supporting the article Differences in nirS-Type Denitrifying Microbial Communities and Their Environmental Drivers in Sediments of Saline Lakes on the Qinghai–Tibetan Plateau, systematically documenting sediment physicochemical parameters of five lakes with distinct salinity gradients on the Qinghai–Tibetan Plateau, measured denitrification kinetics from anaerobic microcosm incubation, nirS gene high-throughput sequencing data, as well as statistical datasets of microbial alpha/beta diversity, taxonomic composition, species co-occurrence network and correlation analysis between microbial community and environmental variables.
