Outline of Final Research Achievements

Bacterial strains were isolated from various environmental samples and applied for aromatic compounds biosorption tests. An isolate showed high adsorption activity against bisphenol A and its biosorption reaction was stable under wide range of pH and temperature. It can be characterized by Freundlich isotherm. Both of duckweed rhizosphere system and calcium alginate immobilized carrier system co-inoculated with adsorbing bacteria combined with degrading bacteria showed efficient removal of BPA comparing with single-inoculated system. These results indicate that not only degrading bacteria but also adsorbing bacteria in the biological treatment system for aromatic compounds play important roles and are useful target of system development.
