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__x0005_ _x0000_ _x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x000E__x0000__x0005__x000F__x0000__x000F__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0012__x0000__x0005__x0013__x0000__x0013__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0016__x0000__x0005__x0017__x0000__x0017__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x001A__x0000__x0005__x001B__x0000__x001B__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0002__x0000__x0000__x0000__x0000__x0000__x001E__x0000__x0005__x001F__x0000__x001F__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000__x0000__x0000__x0000_"_xFFFF__xFFFF__xFFFF__xFFFF__x0005_"_x0000_'_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0006__x0000__x0000__x0000__x0000__x0000__x0002__x0000__x0001__x0003__x0000__x0003__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0006__x0000__x0001__x0007__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0000__x0000__x0000__x0000__x0000_ _x0000__x0001__x000B__x0000__x000B__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000E__x0000__x0000__x0000__x0000__x0000__x0000__x0001__x0001__x0000__x0001__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0003__x0000__x0001__x0003__x0000__x0003__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000_ _x0000__x0005__x0000__x0005__x0005__x0000__x0005__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0007__x0000__x0005__x0007__x0000__x0007__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000__x0000__x0000__x0000__x0000_ _x0000__x0005_ _x0000_ _x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000B__x0000__x0000__x000B__x0000__x0005__x000B__x0000__x000B__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0004__x0000__x0000__x001C__x0000__x0001__x001D__x0000__x001D__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x000F__x0000__x0000__x0000_ _x0000__x0005_!_x0000_!_x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0000__x0003__x0000__x0000__x0000__x0000_'_x0000_ _x0000__x0000__x0000_
