title: Raw sequence reads
design: The V3-V4 domains of the bacterial 16S rRNA gene were amplified with primers, 338F, and 806R. Illumina library built using the NEXTFLEX Rapid DNA-Seq Kit. The library was sequenced by 2300 bp paired-end sequencing using MiSeq Reagent Kit v3 on an Illumina MiSeq platform by Majorbio Bio-Pharm Technology Co. Ltd
