The effect of different antibiotics at several concentrations of ampicillin (0-250 mg/L), benzylpenicillin (0-250 mg/L), novobiocine (0-150 mg/L), oxytetracycline (0-250 mg/L), and chloramphenicol (0-50 mg/L) on a stabilized nitrifying sludge was evaluated under aerated and lithoautotrophic conditions. No effect resulting from the presence of antibiotics on the biomass and nitrate production was noticed. The specific growth rate and volumetric nitrification rate average values for the controls were 8.28 x 10-3/h-1 and 2.74 x 10-3 g/L.h, respectively. Similar rate values were found when different kinds of antibiotic and concentrations were tested. These results may be explained by the nature of the floc or the instability of the antibiotics.
在曝气和无机自养条件下，评估了不同抗生素（氨苄青霉素浓度为0 - 250mg/L、苄青霉素浓度为0 - 250mg/L、新生霉素浓度为0 - 150mg/L、土霉素浓度为0 - 250mg/L、氯霉素浓度为0 - 50mg/L）对稳定化硝化污泥的影响。未观察到抗生素的存在对生物量和硝酸盐产生有任何影响。对照的比生长速率和体积硝化速率平均值分别为8.28×10⁻³/h⁻¹和2.74×10⁻³g/L·h。在测试不同种类抗生素和浓度时发现了类似的速率值。这些结果可以用絮体的性质或抗生素的不稳定性来解释。
