Macrolide pollution has attracted a great deal of attention because its ecotoxic effects on microalgae, but the role phycospheric bacteria under antibiotic stress remains unclear. This study explored toxic erythromycin (ERY) growth and nitrogen metabolism Auxenochlorella pyrenoidosa; then, it analyzed predicted composition ecological function microalgae ERY stress. We found that 0.1, 1.0, 10 mg/L inhibited chlorophyll gradually showed enhanced abilities over course 21 days. As exposure time progressed, nitrate reductase activities increased, remained significantly lower than control group at d. NO3− concentrations in all treatment groups decreased were consistent with growth. NO2− three those during changed community diversity bacteria. The relative abundance bacteria, such as unclassified-f-Rhizobiaceae, Mesorhizobium, Sphingopyxis, Aquimonas, Blastomonas, varied to different degrees. Metabolic functions, ABC transporters, microbial diverse environments, biosynthesis amino acids, upregulated treatments higher (1.0 mg/L). Higher denitrification, nitrous oxide nitrite respiration. findings this suggest alleviate restore by regulating system.
