Triple metal synergy
This study reported a new carbon metabolism management strategy for increased tricarboxylic acid (TCA) cycle anaplerosis to enhance denitrification of low C/N wastewater by the synergistic action of Mo(VI)-Fe(III)-Cu(II) ions. At C/N of 3, Mo(VI)-Fe(III)-Cu(II) regulated carbon partitioning into glyoxylate shunt (GS) with anaplerosis role, further promoting the metabolism of carbon sources by the TCA cycle.
