Aerobic Biodegradation Potential of a Constructed Biozone for Lasagna~TM Soil Remediation Technology

摘要

Thebiodegradation potential of an aerobic microbial process for p-nitrophenol (PNP) biodegrada- tion was evaluated for Lasagna~TM soil remediation technology. A unique, flow-through test cell was designed to pass controlled levels of PNP through an aerated biozone containing Pseudomonas putida PNP1 immobilized on a porous nylon biocarrier. Chemical-loading studies and kinetic analyses de- Termined a pseudo first-order rate constant of 0.036 min~-1 and a half-life of 19.1 min for PNP in The biozone.
