sequences of microorganism
Quality control and filtering were performed on the raw reads obtained from sequencing to generate clean reads for subsequent bioinformatics analysis. The clean reads were then assembled, coding genes were predicted, and a nonredundant gene set was constructed. This gene set was subsequently subjected to functional annotation and taxonomic analysis using both general and specialized databases, and the species composition and abundance of the samples were determined. The final analysis report was completed using the BMKCloud platform (http://www.biocloud.net/).
