Stoichiometry of nitrogen and carbon during RDX degradation calculated based on percentage of reacted RDX using total theoretical numbers on N and C atoms

Element (total no. of atoms)	NO2−	N2O	NH3a	CO2	MW 119	% Recovered
Carbon (3)				30.0b (0.8)e	64.0c	94.0d
Nitrogen (6)	30.0 (1.7)e	1.5 (8.5)e	10.0		48.0f	89.5

^aNo ammonium salt was added to the resting-cell suspension.

^bBased on ¹⁴CO₂ measured using [U-¹⁴C]-RDX.

^cBased on HPLC/radioactivity measurement using [U-¹⁴C]-RDX.

^dTotal of the measured values was 97.6%, distributed as follows: 30% was CO₂ and 67.6% was in the liquid phase, leaving 3% unidentified.

^eValue in parentheses represents relative standard deviation of a triplicate.

^fCalculated based on the empirical formula C₂H₅N₃O₃ found by LC/MS (ES-) and high-resolution MS.
