a Copies of 16S rRNA, narG, nirK, nirS, norB and nosZ genes per gram of sediment at DNA level, RNA level and their ratios (ratio of copies at RNA level to that at DNA level for each gene, RNA: DNA). b Copies of napA gene per gram of sediment, activities of electron transport system (ETS) and denitrifying enzymes at different layers of sediments. Error bars indicate standard errors of three replicates. NAR nitrate reductase, NIR nitrite reductase, NOS nitric oxide reductase, AEZ aerobic zone, HYZ hypoxic zone, ANZ-1 up-anoxic zone, ANZ-2 sub-anoxic zone
