library_construction_protocol: Total genomic DNA was extracted individually using the isopropanol method. Amplification of genomic DNA targeting the V3–V4 region of the 16S rRNA gene was conducted using the paired primers 341F (5′-CCTACGGGNGGCWGCAG-3′) and 805R (5′-GACTACHVGGGTATCTAATCC-3′). PCR products were sequenced using the Illumina Miseq sequencing system (Illumina Inc., USA) according to the manufacturer's instructions.
