Abstract:
In the present study, algicidal bacteria cultivated in an aqueous medium were utilized as a surface modification agent to develop an efficient adsorbent for the removal of Microcystis aeruginosa. The modification considerably enhanced M. aeruginosa cell removal efficiency. Moreover, the introduction of bio-compounds ensured specificity in the removal of M. aeruginosa. Additionally, the cyanotoxin release and acute toxicity tests demonstrated that the adsorption process using the developed adsorbent is environmentally safe. Furthermore, the practical feasibility of the adsorptive removal of M. aeruginosa was confirmed through cell removal tests performed using the developed adsorbent in a scaled-up reactor (50 L and 10 tons). In these tests, the effects of the adsorbent application type, water temperature, and initial cell concentration on the M. aeruginosa removal efficiency were evaluated. The results of this study provide novel insights into the valorization strategy of biological algicides repurposed as adsorbents, and provide practical operational data for effective M. aeruginosa removal in scaled-up conditions.
摘要:
在本研究中,在水性介质中培养的杀菌细菌被用作表面改性剂,以开发一种有效的吸附剂来去除铜绿微囊藻。该修饰显著提高了铜绿假单胞菌细胞去除效率。此外,生物化合物的引入确保了铜绿假单胞菌去除的特异性。此外,氰基毒素释放和急性毒性试验表明,使用开发的吸附剂的吸附过程是环境安全的。此外,通过使用开发的吸附剂在放大的反应器(50升和10吨)中进行的细胞去除测试,证实了吸附去除铜绿假单胞菌的实际可行性。在这些测试中,吸附剂应用类型的影响,水温,和初始细胞浓度对铜绿假单胞菌的去除效率进行了评价。这项研究的结果为重新用作吸附剂的生物灭藻剂的增值策略提供了新的见解,并为在放大条件下有效去除铜绿假单胞菌提供实际的操作数据。
