Summary:In this study, we aim to evaluate the degrading performance of organics and nutrients by a biological activated carbon (BAC), which was manufactured by immobilizing Pseudomonas putida having ability to degrade aromatic carbon compound on activated carbon, a material to use remediation of organic pollutants contaminated lake sediment. A culture with BAC showed higher degrading performance (93.1%, 54.4%, and 95.5% for removal of organics, total nitrogen, and total phosphorus, respectively) compared to those of suspended culture with only P. putida (68.0%, 33.9%, and 24.1% for removal of organics, total nitrogen, and total phosphorus, respectively). In order to show application ability for real domestic lake environment, culture experiments to remove organic compounds and nutrients were performed at temperature of 10, 18, and 26o C, respectively. Effective removal performance of organics and nutrients was confirmed at a culture temperature of 18o C and over. Also, feasibility of BAC to remediate persistent organics contaminated sediment was confirmed by the result of phenol degrading culture experiment (94.3% phenol removal after 12 h).
