title: SB26
design: MiSeq sequencing was performed  using 515F (5-GTGYCAGCMGCCGCGGTA-3) (Parada et al., 2016) and 928R (5- CCCCGYCAATTCMTTTRAGT-3) (Wang and Qian, 2009) primers for amplification of 16S rRNA gene. The resulting PCR products were purified and loaded onto the Illumina MiSeq cartridge according to the manufacturer instructions. The quality of the run was checked internally using PhiX, and then each pair-end sequences were assigned to its sample with the help of the previously integrated index
