Abstract :
The contamination of ground and surface water with methyl tert-butyl ether (MTBE) has evoked substantial attention due to the frequent occurrence of storage tank leakage. Kinetic analysis of MTBE degradation by polyethyleneimine stabilized beads with alginate immobilized Methylibium petroleiphilum PM1 was investigated in this paper. The results showed that the stabilized beads could be used wider in respect to pH value, temperature and initial MTBE concentration than freely-suspended cells under the same conditions. The biochemical reaction rather than intraparticle diffusion resistance was considered as the key step by the kinetic analysis.
