A biogas slurry composed of carbon, nitrogen, phosphorus, and antibiotics was generated. Investigations into the nutrient and tetracycline removal performance of four microalgae-based contaminant removal technologies, including Chlorella vulgaris, C. vulgaris co-cultured with endophytic bacteria, C. vulgaris co-cultured with Ganoderma lucidum, and C. vulgaris co-cultured with G. lucidum and endophytic bacteria, were conducted. The algal-bacterial-fungal consortium with 10 M strigolactone (GR24) yielded the maximum growth rate and average daily yield for algae at 0.325 ± 0.03 d and 0.192 ± 0.02 g L d, respectively. The highest nutrient/ tetracycline removal efficiencies were 83.28 ± 7.95 % for chemical oxygen demand (COD), 82.62 ± 7.97 % for total nitrogen (TN), 85.15 ± 8.26 % for total phosphorus (TP) and 83.92 ± 7.65 % for tetracycline. Adding an algal-bacterial-fungal consortium with an optimal synthetic analog GR24 concentration is seemingly an encouraging strategy for enhancing pollutant removal by algae, possibly overcoming the challenges of eutrophication and antibiotic pollution.
产生了一种由碳、氮、磷和抗生素组成的沼液。对四种基于微藻的污染物去除技术的营养物和四环素去除性能进行了研究，这四种技术包括普通小球藻、与内生细菌共培养的普通小球藻、与灵芝共培养的普通小球藻以及与灵芝和内生细菌共培养的普通小球藻。含有10 M独脚金内酯（GR24）的藻 - 细菌 - 真菌联合体使藻类的最大生长速率和平均日产量分别达到0.325±0.03 d和0.192±0.02 g L d。化学需氧量（COD）的最高营养物/四环素去除效率为83.28±7.95%，总氮（TN）为82.62±7.97%，总磷（TP）为85.15±8.26%，四环素为83.92±7.65%。添加具有最佳合成类似物GR24浓度的藻 - 细菌 - 真菌联合体似乎是一种促进藻类去除污染物的令人鼓舞的策略，可能克服富营养化和抗生素污染的挑战。
