This study aimed to achieve three primary objectives: (1) to isolate high-performance biofilm-forming microalgal strains through systematic phenotypic screening;(2) to characterize the structural and functional properties of their extracellular polymeric substances (EPS) using integrated spectroscopic techniques; and (3) to demonstrate the practical applications of these biopolymers in microalgal biomass harvesting and antibiotic removal. The experimental approach integrated microbial isolation methods with advanced material characterization and environmental biotechnology strategies. A high-performance biofilm-forming algal strain was isolated based on its wall-adhesion capacity and taxonomically identified. Various EPS extraction protocols were systematically evaluated to determine the most effective method, and structural analysis was conducted using Fourier-transform infrared spectroscopy (FTIR). The functional properties of the extracted EPS were assessed through flocculation assays, antibacterial zone tests, and high-performance liquid chromatography (HPLC). Results showed that the isolated strain FJPN1, identified as Chlorella sorokiniana, exhibited exceptional biofilm-forming capability with a wall-adhesion rate of 96.8%. The ion-exchange resin method yielded the highest EPS quantity (295 mg/g), and FTIR analysis revealed the presence of characteristic functional groups in the polysaccharide-protein complexes, including hydroxyl, amino, and glycosidic bonds. Functional studies demonstrated that EPS at a concentration of 0.5 g/L induced a flocculation efficiency of 90.5% in Chlorella vulgaris FACHB-8. Notably, FJPN1 achieved complete removal (100%) of gentamicin and kanamycin at a concentration of 0.5 g/L and retained full removal efficiency in 50% diluted industrial wastewater. Mechanistic analysis confirmed that biosorption mediated by EPS was the dominant removal mechanism. The dual functionality of C. sorokiniana FJPN1, enabling efficient heterospecific microalgal flocculation and selective removal of aminoglycoside antibiotics, highlights its potential as a novel functional bioresource for microalgal biomass harvesting and antibiotic pollution removal.

本研究旨在筛选具有高生物膜形成能力的微藻,解析微藻胞外聚合物(Extracellular Polymeric Substances, EPS)组分与功能特性,并评估其在微藻絮凝及抗生素去除中的应用潜能。通过微藻的贴壁成膜特性筛选目标藻株并进行鉴定;对提取EPS的不同方法进行对比,采用傅里叶变换红外光谱(FTIR)表征EPS结构;通过絮凝实验验证EPS絮凝活性,利用抑菌圈法与高效液相色谱(HPLC)评估微藻抗生素的去除能力。本研究获得一株高成膜性(贴壁率高达96.83%)微藻FJPN1,经鉴定为Chlorella sorokiniana。优选离子交换树脂法提取藻株FJPN1的EPS(产率295 mg/g),FTIR分析揭示其含多糖-蛋白复合物及羟基、氨基等功能基团。功能研究结果显示:0.5 g/L EPS可使普通小球藻絮凝率达90.51%;藻株FJPN1对庆大霉素和卡那霉素(0.5 g/L)的去除率达到100%,且在50%(稀释1倍)抗生素生产废水中的去除率仍达到100%,抗生素去除机制以EPS生物吸附为主。藻株FJPN1兼具异种微藻高效絮凝与氨基糖苷类抗生素特异性去除功能,为微藻采收及抗生素污染治理提供了新型功能性生物资源。

本研究旨在筛选具有高生物膜形成能力的微藻,解析微藻胞外聚合物(Extracellular Polymeric Substances, EPS)组分与功能特性,并评估其在微藻絮凝及抗生素去除中的应用潜能。通过微藻的贴壁成膜特性筛选目标藻株并进行鉴定;对提取EPS的不同方法进行对比,采用傅里叶变换红外光谱(FTIR)表征EPS结构;通过絮凝实验验证EPS絮凝活性,利用抑菌圈法与高效液相色谱(HPLC)评估微藻抗生素的去除能力。本研究获得一株高成膜性(贴壁率高达96.83%)微藻FJPN1,经鉴定为Chlorella sorokiniana。优选离子交换树脂法提取藻株FJPN1的EPS(产率295 mg/g),FTIR分析揭示其含多糖-蛋白复合物及羟基、氨基等功能基团。功能研究结果显示:0.5 g/L EPS可使普通小球藻絮凝率达90.51%;藻株FJPN1对庆大霉素和卡那霉素(0.5 g/L)的去除率达到100%,且在50%(稀释1倍)抗生素生产废水中的去除率仍达到100%,抗生素去除机制以EPS生物吸附为主。藻株FJPN1兼具异种微藻高效絮凝与氨基糖苷类抗生素特异性去除功能,为微藻采收及抗生素污染治理提供了新型功能性生物资源。

This study aimed to achieve three primary objectives: (1) to isolate high-performance biofilm-forming microalgal strains through systematic phenotypic screening;(2) to characterize the structural and functional properties of their extracellular polymeric substances (EPS) using integrated spectroscopic techniques; and (3) to demonstrate the practical applications of these biopolymers in microalgal biomass harvesting and antibiotic removal. The experimental approach integrated microbial isolation methods with advanced material characterization and environmental biotechnology strategies. A high-performance biofilm-forming algal strain was isolated based on its wall-adhesion capacity and taxonomically identified. Various EPS extraction protocols were systematically evaluated to determine the most effective method, and structural analysis was conducted using Fourier-transform infrared spectroscopy (FTIR). The functional properties of the extracted EPS were assessed through flocculation assays, antibacterial zone tests, and high-performance liquid chromatography (HPLC). Results showed that the isolated strain FJPN1, identified as Chlorella sorokiniana, exhibited exceptional biofilm-forming capability with a wall-adhesion rate of 96.8%. The ion-exchange resin method yielded the highest EPS quantity (295 mg/g), and FTIR analysis revealed the presence of characteristic functional groups in the polysaccharide-protein complexes, including hydroxyl, amino, and glycosidic bonds. Functional studies demonstrated that EPS at a concentration of 0.5 g/L induced a flocculation efficiency of 90.5% in Chlorella vulgaris FACHB-8. Notably, FJPN1 achieved complete removal (100%) of gentamicin and kanamycin at a concentration of 0.5 g/L and retained full removal efficiency in 50% diluted industrial wastewater. Mechanistic analysis confirmed that biosorption mediated by EPS was the dominant removal mechanism. The dual functionality of C. sorokiniana FJPN1, enabling efficient heterospecific microalgal flocculation and selective removal of aminoglycoside antibiotics, highlights its potential as a novel functional bioresource for microalgal biomass harvesting and antibiotic pollution removal.
