title: Dynamic of bacterial community in activated sludge of an anoxic-aerobic MBR under different operational regimes
design: Diversity profiling, 16S rRNA gene: 27F - 519R. MBR was run under four main operational regimes to evaluate the MBR performance and to determine the role of internal recirculation (IR) ratio and redox conditions on the nutrient and trace organic contaminant (TrOC) removal by the system. This sample was collected from anoxic reactor under SRT of 25 d, with IR of 3 and no TrOCs.
