Unique microbial community assembly in urban rivers
he microbially-mediated water blackening and odorization in polluted urban rivers is an emerging environmental problem in populated developing countries. Information on the microbial community assembly and the assembly driving process in the black-odorous urban rivers remain elusive. Here, in a field study based on water and sediment samples collected from 200 polluted urban rivers of 82 cities in China and Indonesia, combined with laboratory water-sediment column experiments, we demonstrated unique microbial community assembly in the black-odorous urban rivers
