STUDY ON EFFECTS OF MICROORGANISM IN DEPOLYMERIZATION PROCESS OF XENOBIOTIC POLYMERS BY MODELING AND SIMULATION

摘要

Effects of microorganism in biodegradation process of polyethylene glycol are studied by modeling and simulation. Dynamics of population of microorganism is taken into consideration in modeling of depolymerization process of exogenous type, and a mathematical model is described. A molecular factor of degradation rate is obtained by solving an inverse problem, and a time factor of degradation is obtained by analyzing the dynamics of population of microorganism. Once the time factor and the molecular factor of degradation rate are determined, a depolymerization process is simulated by solving an initial value problem.
