Title:Nitrate addition is an effective strategy to control sulfide generation in wastewater bioreactors having high surface biofilm area to water volume. Nitrate addition stimultaed sulfide-oxidising Thiomicrospira denitrificans-related bacteria, which resulted in the elimination of most sulfide from the biofilms.
