CONTINUOUS AEROBIC DEGRADATION OF DINITROTOLUENES BY IMMOBILIZED MIXED MICROBIAL POPULATION

摘要

This study describes biodegradation characteristics of the individual 2,4-DNT and 2,6-DNT by a defined mixed culture in packed bed bioreactor. The reactor was packed with poraver. All continuous degradation procedures were carried out at excess of oxygen that enabled to achieve the complete pollutant mineralization. The loading characteristics proved higher biodegradation rate and efficiency of 2,4-DNT than for 2,6-DNT.
