With the growth of the aquaculture industry, antibiotic residues in treated wastewater have become a serious ecological threat. The effects of supplementation with diethyl aminoethyl hexanoate (DA-6) on the removal of tetracycline (TC), ciprofloxacin (CPFX), and sulfamonomethoxine (SMM) from aquaculture wastewater by different microalgae-based systems were examined and systematically analyzed. The results demonstrated that C. vulgaris -S395-2-C. rosea symbiont performed best under 0.2 mg L antibiotic treatment for antibiotic removal. At 10 M, DA-6 significantly enhanced C. vulgaris-S395-2-C. rosea symbiont removal of CPFX and SMM at 0.20 mg L. The removal of TC, CPFX and SMM by this strain under optimal conditions was 99.2 ± 0.4 %, 86.3 ± 6.3 %, and 91.3 ± 5.7 %, respectively. These results suggest that DA-6 may act on microalgae-bacteria-fungi three-phase symbionts for the removal of multiple antibiotics from aquaculture wastewater.
随着水产养殖业的发展，经处理废水中的抗生素残留已成为严重的生态威胁。本研究考察并系统分析了二乙氨基乙基己酸（DA-6）对不同微藻基系统去除水产养殖废水中四环素（TC）、环丙沙星（CPFX）和磺胺甲恶唑（SMM）的影响。结果表明，在 0.2mg L 抗生素处理下，小球藻 -S395-2-玫瑰螺旋藻共生体的表现最佳，抗生素去除效果最好。在 10μM 时，DA-6 可显著增强小球藻 -S395-2-玫瑰螺旋藻共生体对 0.20mg L CPFX 和 SMM 的去除效果。在最佳条件下，该菌株对 TC、CPFX 和 SMM 的去除率分别为 99.2±0.4%、86.3±6.3%和 91.3±5.7%。这些结果表明，DA-6 可能作用于微藻-细菌-真菌三相共生体，从而从水产养殖废水中去除多种抗生素。
