Fig. 1From: Evidences towards deciphering the mode of action of dimethylpyrazole-based nitrification inhibitors in soil and pure cultures of Nitrosomonas europaeaEffect of DMPP and DMPSA nitrification inhibitors on Nitrosomonas europaea pure cultures through monitoring the evolution of NH4+ (a) and NO2− (b) in the growth medium during 7 days. Bacterial density (OD600) was determined at the end of the experiment (c). For panel C different letters indicate significant differences using one-way ANOVA followed by Duncan’s post hoc test (p < 0.01; n = 3). AS means ammonium sulphateBack to article page
