16S rRNA gene-Seq: water samples
PCR amplification of the 16S rRNA gene was carried out with primers 515F (5-GTGCCAGCMGCCGCGGTAA-3) and 806R (5-GGACTACHVGGGTWTCTAAT-3). Barcoded amplicons were pair-end sequenced on Illumina MiSeq platform at Genome Quebec (Mcgill University, Montreal, Quebec, Canada).
