V3-V4 region of 16S rRNA was amplified with PCR. The primers were 341F and 805R. PCR products were confirmed with electrophoresis and purified using QIAquick PCR purification kit (Qiagen, Valencia, CA, USA). The purified PCR products were tagged with Illu_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000_rs_x0000_m Ne_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000_ll_x0000_e, S_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000_or_x0000_E fr_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000_d _x0000_e Fa_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000_io_x0000_u (F_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0002__x0000__x0000__x0000__x0000_PC_x0000_ulic_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000__x0000__x0000_ Q_xFFFF__xFFFF__xFFFF__xFFFF_-iT_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0006__x0000__x0000__x0000__x0000_y _x0000_)The_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000_ W_x0000_igto_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000_li_x0000_a 30_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000E__x0000__x0000__x0000_CR_x0000_auct_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000_ F_x0000_Qrep_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000_ it_x0000_e qu_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000_on_x0000_etio_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000__x0000__x0000__x0000_ p_x0000_et s_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000B__x0000_ B_x0000_elyz_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000_ A_x0000_!CA,_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000__x0000__x0000_ c_xFFFF__xFFFF__xFFFF__xFFFF_et C_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0003__x0000__x0000__x0000_ou_x0000_irea_x0000__x0000__x0000_
