摘  要:
To study the influence of differences in C2H2 concn on the production of CO2, N2O, NH4-N and volatile fatty acids (VFA), soil slurries (soil, rye straw and KNO3 solution) with a gradient in C2H2 concn were anaerobically incubated at 25 degC for 2 weeks. Acetate, butyrate and CO2 production and NH4-N accumulation were inhibited in the slurries in the presence of C2H2 and the inhibition effect increased with increasing C2H2 from 0 to 20 kPa in the headspace gas of the incubation bottle. However, N2O, isobutyrate and propionate production was not obviously different among the slurries amended with C2H2 from 2.5 to 20 kPa. The results showed that the C2H2 did not promote the inhibition but only increased the side effect on other microbial processes. C2H2 at 2.5 kPa was the optimum choice for the such denitrification studies.
