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__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0002__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000__x0000__x0000__x0000__x0000__xFFFF__xFFFF__xFFFF__xFFFF__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0006__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000E__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000_ _x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000B__x0000__x0000__x0000__xDB00__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000__x0000__x0000__xDB00__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000__x0000__xDB00__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0003__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000_
