^aTitanous chloride replaced sulfide as the reductant. 

^bPercentages were calculated based on the following equation (see text): C₂H₇O₃NS→0.5 C₂H₄O₂ + CO₂ + NH₄⁺ + HS⁻. 

^cValues were corrected for the initial sulfide concentration and the initial ammonia concentration used as the reductant and the nitrogen source, respectively. 

^dND, not detected.
