Abstract

The authors regret that on page 16, the last sentence in the 1st paragraph and the Equations 1-3 of Section 4.1, and on page S3 of the Supplementary Information, the authors have been made aware of an error in the free energy of formation for AsO43- and AsO2-. A mistake in the Gibbs energy values of AsO43- and AsO2- were -55 and -83.66 kJ/mol, which need to be corrected to be -155 and -83.66 kcal/mol, respectively. Unit conversions in the calculation of Equations 1-3 were not performed and produced wrong Δ [Formula presented]value. We present here corrected Δ [Formula presented]value of Equations 1-3 and attached a corrected Supplementary Information as below. Error: Accordingly, we predicted that anaerobic ammonium oxidation coupled to As(V) reduction would also generate N2, NO2-, or NO3- similar to Feammox but would yield more energy through the following reactions (Equations 1-3) (see Supplementary Material for the calculation of Δ [Formula presented]: [Formula presented] [Formula presented] [Formula presented]Corrected: Accordingly, we predicted that anaerobic ammonium oxidation coupled to As(V) reduction would also generate N2, NO2-, or NO3- similar to Feammox and would yield energy through the following reactions (Equations 1-3) (see Supplementary Material for the calculation of Δ [Formula presented]: [Formula presented] [Formula presented] [Formula presented]Though the Gibbs energy need to be corrected, our discussion and conclusion still works. All the three Asammox pathways were energetically favoured (Δ [Formula presented]< 0) and Asammox to N2 stoichiometrically obtained most energy (minimum Δ [Formula presented] among the three pathways.
