title: Pyrosequencing result of the actived sludge and river sediment sample
organism: activated sludge metagenome
description: 454 pyrosequencing of V1-V3 hypervariable regions in rRNA genes was used to explore microbial communities from 22 activated sludge samples and 13 river sediment samples. Totally, 470627 effective reads were generated from these 35 samples. These reads were assigned into different taxonomies by using RDP classifier. Besides, Cluster analysis, PCoA, correlation analysis was also used to assess the beta-diversity among all these samples.
