Impacts of substrate properties and aquatic nutrient concentrations on the relative abundance of nitrifying/denitrifying genes and the associated microbes in epilithic biofilms
to reveal the Impacts of substrate properties and aquatic nutrient concentrations on the relative abundance of nitrifying/denitrifying genes and the associated microbes in epilithic biofilms. Our study highlights the influence of altering substrate heterogeneity in river projects on shaping the functional gene compositions and the related nitrifier/denitrifier communities.
