Study on Degrading Phenol by Immobilized Ralstonia metallidurans CH34 / 微生物学通报

ABSTRACT

The subject of this study is to improve the ability of Ralstonia metallidurans CH34, a phenol-degrading strain with anti-heavy metal feature by immobilization.The optimal conditions for immobilizing bacterial cells were obtained with cross act experiment. The phenol-degrading efficiency of immobilized Ralstonia metallidurans CH34 was investigated. Results show that phenol-degrading efficiency of immobilized cells is obviously superior to that of the free cells; The ability of its resistance to heavy metal have been greatly improved; When additional carbon sources were added in the simulated waste water, the immobilized R. metallidurans CH34 were affected less than the free cells.
