Abstrakt: Microbial communities under Alpine regions show significant regional variation. As a main factor affecting microbial communities and metabolic processes, temperature was used as a single-factor control condition for 16S rRNA high-throughput sequencing analysis of microbial communities in anaerobic treatment systems in Alpine regions based on the Illumina MiSeq sequencing platform, and functional prediction was explored using the PICRUSt2 database. The results show that the biotic environment in Alpine regions can reduce microbial diversity. The microbial community composition is partially similar, and the microbial metabolic processes are slightly different. Low temperatures favor the methanogenesis module reaction, and for energy metabolism, 25°C is the optimal temperature working condition. [ABSTRACT FROM AUTHOR]
