title: Control sample 2
design: In summary, the amplification of the V3V4 region of the bacterial 16s rRNA genes were performed with the primers 338F (5-barcode-ACTCCTRCGGGAGGCAGCAG)-3 and 806R (5-GGACTACCVGGGTATCTAAT-3), where the barcode is an 8-base sequence exclusive to each sample.  All amplicon libraries were purified and paid-end sequenced on an Illumina MiSeq platform (Illumina Inc., San Diego, CA). The  processing of the raw Illumina fastq files was performed with Quantitative Insights into Microbial Ecology (QIIME v1.9.0)
