ABSTRACT=<p>Composting livestock manure using microorganisms is a safe and resourceful practice. The continual fluctuations in physicochemical parameters during composting are intricately linked to the composition of microbial communities. This study investigated the dynamics of microbial communities during the composting of cow manure and tobacco straw using amplicon sequencing and shotgun metagenomics. The sequencing results revealed major genera such as <italic>Sphaerobacter</italic>, <italic>Actinomadura</italic>, <italic>Thermomonospora</italic>, <italic>Flavobacterium</italic>, <italic>Bacillus</italic>, <italic>Hydrogenophaga</italic>, <italic>Pseudomonas</italic>, <italic>Lysinibacillus</italic>, <italic>Aneurinibacillus</italic>, and <italic>Azotobacter</italic>. Metagenomic analysis highlighted that the phylum Proteobacteria constituted the largest proportion. Furthermore, the presence of the genus <italic>Rhodococcus</italic>, known to cause human and animal diseases, gradually decreased over time. These findings offer initial insights into the microbial community composition and function during cow manure and tobacco straw composting.</p>
