Abstract：
The formation of symbionts by using different combinations of endophytic bacteria, microalgae, and fungi to purify antibiotics-containing wastewater is an effective and promising biomaterial technology. As it enhances the mixed antibiotics removal performance of the bio-system, this technology is currently extensively studied. Using exogenous supplementation of various low concentrations of the phytohormone strigolactone analogue GR24, the removal of various antibiotics from simulated wastewater was examined. The performances of Chlorella vulgaris monoculture, activated sludge-C. vulgaris-Clonostachys rosea, Bacillus licheniformis-C. vulgaris-C. rosea, and endophytic bacteria (S395-2)-C. vulgaris-C. rosea co-culture systems were systematically compared. Their removal capacities for tetracycline, oxytetracycline, and chlortetracycline antibiotics from simulated wastewater were assessed. Chlorella vulgaris-endophytic bacteria-C. rosea co-cultures achieved the best performance under 0.25 mg L-1 antibiotics, which could be further enhanced by GR24 supplementation. This result demonstrates that the combination of endophytic bacteria with microalgae and fungi is superior to activated sludge-B. licheniformis-microalgae-fungi systems. Exogenous supplementation of GR24 is an effective strategy to improve the performance of antibiotics removal from wastewater.
摘要：
利用内生细菌的不同组合形成共生体，微藻,和真菌净化含抗生素废水是一种有效且有前途的生物材料技术。由于它增强了生物系统的混合抗生素去除性能，这项技术目前被广泛研究。使用外源补充各种低浓度的植物激素strgolactone类似物GR24，检查了从模拟废水中去除各种抗生素的情况。小球藻的表现，活性污泥C.vulgaris-ClonostachysRosea,地衣芽孢杆菌C.普通C.Rosea,和内生细菌（S395-2）-C。普通C.系统比较了罗西阿共培养系统。它们对四环素的去除能力，土霉素,并对模拟废水中的金霉素类抗生素进行了评价。小球藻-内生细菌-C.罗西共培养在0.25mgL-1抗生素下达到最佳性能，可以通过补充GR24进一步增强。该结果表明，内生细菌与微藻和真菌的组合优于活性污泥B。地衣-微藻-真菌系统。外源性补充GR24是提高废水中抗生素去除性能的有效策略。
