16S metagenome of marine denitrifying biofilm cultures

The biofilm of a continuous, methanol-fed, fluidized denitrification system that treated a marine effluent is composed of multi-species microorganisms. The original biofilm (OB) taken from the Biodome denitrification system was cultured under batch-mode, anoxic conditions at laboratory scale in an artificial seawater (ASW) and exposed to a range of specific physico-chemical parameters. We determined the composition of the bacterial community in the OB and the biofilm cultures by 16S metagenomic approach.
