Effect of increased Cu2+ and Zn2+ concentration on Nitrosomonas europaea growth and nitrification capacity determining NH4+ (a), NO2− (b), and bacterial density (OD600) (c) in the growth medium after 7 days of treatment application Cu2+ and Zn2+ concentrations used were 0.01 mg L−1 as control dose and 2.50 mg L−1 as a higher dose. AS means ammonium sulphate (AS) different letters indicate significant differences using one-way ANOVA followed by Duncan’s post hoc test (p < 0.01; n = 3)
