The adsorption of the veterinary medicinal products (VMP) tetracycline (TET), ciprofloxacin (CIP), sulfadiazine (SDZ) and sulfamethoxazole (SMX) onto a dried Scenedesmus almeriensis microalgae-bacteria consortium was studied at several equilibrium concentrations (20 to 1000 μg/L). Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) analysis were performed to investigate the surface morphology of the microalgae and to identify the effect of the antibiotics´ functional groups on the surface of the consortium of S. almeriensis and bacteria. Ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) was used to determine the feasibility of this consortium for the removal of antibiotics via biosorption. Freundlich and Langmuir adsorption models were used for the mathematical description of the adsorption equilibrium. Pseudo-first order and pseudo-second order kinetic models were applied to fit the biosorption experimental data. Relative antibiotic removal was higher at low equilibrium concentrations. In the range of the initial VMP concentration studied, ciprofloxacin and tetracycline exhibited the highest removal efficiency of 43–100% and 75–82%, respectively. Likewise, ciprofloxacin and tetraciclyne presented the highest adsorption rates of 0.11–26.66 and 1.78–27.09 mg·μg⁻¹·h⁻¹, respectively. This study revealed that the S. almeriensis-bacteria consortium has a high biosorption power and proved that biosorption is an important mechanism in the removal of ciprofloxacin and tetraciclyne using a microalgae-based water treatment process. However, sulfadiazine and sulfamethoxazole removals did not exceed 32%.

在兽药产品（VMP）四环素（TET），环丙沙星（CIP），磺胺嘧啶（SDZ）和磺胺甲恶唑（SMX）到干燥的吸附栅藻almeriensis微藻细菌财团研究在几个平衡浓度（20至1000微克/ L)。进行扫描电子显微镜 (SEM) 和傅里叶变换红外光谱 (FTIR) 分析以研究微藻的表面形态并确定抗生素官能团对S. almeriensis 聚生体表面的影响和细菌。超高效液相色谱串联质谱 (UHPLC-MS/MS) 用于确定该联合体通过生物吸附去除抗生素的可行性。Freundlich 和 Langmuir 吸附模型用于吸附平衡的数学描述。应用伪一级和伪二级动力学模型来拟合生物吸附实验数据。在低平衡浓度下，抗生素的相对去除率更高。在研究的初始 VMP 浓度范围内，环丙沙星和四环素的去除效率最高，分别为 43-100% 和 75-82%。同样，环丙沙星和四环素的吸附率最高，分别为 0.11-26.66 和 1.78-27.09 mg·μg ^-1 ·h ^-1， 分别。该研究揭示了S. almeriensis -bacteria consortium 具有很高的生物吸附能力，并证明生物吸附是使用微藻水处理工艺去除环丙沙星和四环素的重要机制。然而，磺胺嘧啶和磺胺甲恶唑的去除率不超过 32%。
