Abstract
Rhizobium trifolii, R. leguminosarum, andR. “hedysarum”, grownex planta under anoxic conditions in a chemically defined medium, evolve N2O from NO3 −, NO2 −, and (NH4)2NO3. The amount of nitrous oxide formed after 96 hours is about 0.2μM×mg−1 cells d.w. Large availability of organic matter enhances the production of N2O from nitrate by free-livingR. trifolii in peat/sand mixtures. Denitrification of the above species andR. meliloti was detected also in planta. Nitrous oxide production increases almost linearly from 10–45μM×mg−1 nodules d.w. when nitrogen-fixing plants are exposed to increasing concentrations of nitrate (1–12μM).This publication has 13 references indexed in Scilit:
