“…To date, prior studies on microorganisms in plateau regions have focused on the Tibetan, Loess, and Mongolian Plateaus. These studies have involved variations in soil enzyme activities and microbial communities along elevation gradients ( Fan et al, 2021 ), reflections of functional microorganisms in soil to natural factors such as nitrogen deposition and precipitation ( Xu et al, 2021 ; Li et al, 2023 ), or different responses of soil microorganisms from different plant communities to changes in environmental stresses ( Xu et al, 2023 ). Relatively few studies have been conducted on the distribution of bacterial communities in East Pamir.…”

Altitude and ultraviolet (UV) radiation may affect the community composition and distribution of microorganisms in soil ecosystems. In this study, 49 soil samples from 10 locations were collected from different elevations on the eastern Pamir Plateau and analyzed for soil microbial community structure and function using high-throughput sequencing. The results showed that soil samples from different elevations of the eastern Pamir Plateau contained 6834 OTUs in 26 phyla and 399 genera. The dominant phyla common to different elevations were Actinobacteria, Proteobacteria, Bacteroidota, Acidobacteriota, and Gemmatimonadota. The dominant genera were Rubrobacter, Sphingomonas, Nocardioides, and Solirubrobacter. Species richness increased slightly with elevation, and there were significant differences in community composition between the elevations. Elevation and UV exposure are important factors that drive changes in bacterial communities. The results of the KEGG pathway showed that drug resistance, antineoplastic, aging, replication, and repair were enhanced and then slightly decreased with increasing elevation. Bacterial communities at different elevations were rich in radiation-resistant microorganisms, and the main genera were Rubrobacter, Sphingomonas, Nocardioides, Pontibacter, and Streptomyces. The findings have shown the composition and distribution of bacterial communities at different elevations on the Eastern Pamir Plateau. Potentially radiation tolerant microbial species were also examined. The results are of considerable importance for the succession of bacterial microorganisms in the plateau region, the study of radiation tolerant bacterial germplasm resources, and the application of biofunctionality.

Nitrogen is a component of many fundamental biomolecules and also participates in environmental redox chemistry. Nitrogen pollution is a serious environmental problem. Biological nitrogen removal is one of the most significant issues in wastewater treatment. Microbial-driven nitrogen transformations are carried out through metabolic pathways. Wastewater treatment systems using microalgal-bacterial cocultures can improve nutrient removal efficiency through interspecies synergistic interactions. However, relevant studies on the nitrogen metabolism and microbial characteristics of microalgal-bacterial systems have not been systematically reviewed and discussed. This Review comprehensively analyzes nitrogen contaminants in various biological nitrogen removal microalgal-bacterial composite systems and summarizes the microbial characteristics and nitrogen-metabolizing enzymes present. Nitrogen metabolism regulation methods involving quorum sensing and genetic regulation are described, and methods of enhancing microbial nitrogen removal through microbial community interactions, enhancing enzyme activity, and promoting electron transfer are introduced in detail. This Review provides a perspective on the improvement and optimization of microalgalbacterial wastewater treatment technology through analyzing the nitrogen metabolism and increasing process performance.
