- Abstract
In this study, immobilization technique was employed to improve simultaneous algicidal and denitrification of immobilized Acinetobacter sp. J25 with magnetic FeO in eutrophic landscape water. After 7 days of operation, the maximum superoxide dismutase (SOD) activity (54.43 U mg), nitrate removal efficiency (100% (0.2127 mg L h)), and chlorophyll-a removal efficiency (89.71%) were obtained from the immobilized J25 with magnetic FeO. The results suggest that immobilized J25 with magnetic FeO had better nitrogen removal efficiency and algicidal activity in eutrophic landscape water. High-throughput sequencing data profiled the strain J25 that was immobilized with magnetic FeO which changed the composition of the microbial community. The results indicated a novel concept of enhancing the algicidal and denitrification property of immobilized bacteria with magnetic FeO in eutrophic landscape water.
