| Résumé | This study presents a comparison of denitrification rates and denitrification stoichiometry when using different sources of carbon. Denitrification tests were carried out in test bottles containing water and soil samples acquired at a nitrate-contaminated site and supplemented with either sucrose, acetate or ethanol. The tests demonstrated nitrate removal in all carbon source supplemented bottles. The rate of denitrification and the required amount of a carbon source, however, depended on the choice of substrate. Ethanol and acetate were found to provide the highest denitrification rate, that of 1.4 - 1.6 mg-N I⁻¹ d⁻¹. Sucrose-supplemented bottles demonstrated a significantly slower denitrification rate, that of 0.6 - 0.9 mg-N I⁻¹ d⁻¹. In addition to slow denitrification rates, sucrose-supported denitrification required more carbon source. |
